How to install and configure PostGIS Raster on Windows

March 10, 2011

A lot of people ask me about how to use PostGIS Raster and the GDAL PostGIS Raster driver in Windows systems. And most of them are, comprehensibly, using the last stable releases of both libraries (PostGIS and GDAL). The problem is PostGIS Raster and GDAL driver are being developed in these moments. There’s no stable release, so far.

PostGIS Raster was included as official part of PostGIS in October 2010. The old version, formerly named WKT Raster has been abandoned. So, if you want to use PostGIS Raster, with new functionalities and many bugs fixed, you’ll have to use the latest PostGIS development snapshot. The use of the old WKT Raster extension is strongly unrecommended, and there’s no support for it.

About GDAL, there was an important change in the driver on October 20st, 2010. A new version was committed, and this is the only version that works with PostGIS Raster. This new driver version was included in the release 1.8.0, currently the stable release. So, the use of an older release to connect with PostGIS Raster is also unrecommended.

With these facts in mind, I understand the Windows users who want to use PostGIS Raster and the GDAL driver are a bit unprotected. I’m not a Windows user, but I consider it my fault. For this reason, I’ve decided to create this howto. I’m going to install and configure PostGIS Raster and GDAL in Windows. And fortunately, you don’t need to compile anything. Let’s go for it:

Enviroment: Windows 7 32 bits

Step 1: Installing Python and Numpy

PostGIS Raster loader uses GDAL Python bindings and numpy. So, we’ll first install Python and numpy. Several options here:

  • Python 2.5, unofficial numpy 1.5.1 (download numpy-1.5.1.win32-py2.5.‌exe from here)
  • Python 2.6, unofficial numpy 1.5.1 (download numpy-1.5.1.win32-py2.6.‌exe from here)
  • Python 2.7, unofficial numpy 1.5.1 (download numpy-1.5.1.win32-py2.7.‌exe from here)

I’m using:

  • Python 2.6.6
  • Numpy 1.5.1 (numpy-1.5.1.win32-py2.6.‌exe)

Step 2: Installing GDAL

I think the easiest way to have a complete GDAL installation (library + binaries + Python bindings) working on Windows is using the GDAL binaries mantained by Tamas Szekeres, here. Last GDAL versions from trunk are compiled daily with MSVC 2003, MSVC 2005 and MSVC 2008. Pick one. For example, the version compiled with MSVC 2003, here.

The  faster way now would be to download the generic installer for the GDAL core components, and choose the complete installation

GDAL 1.8.0 core installer for Windows

GDAL 1.8.0 core installer for Windows

After the installation, you will need to add C:\Program Files\GDAL\ to the PATH enviroment var. And create this new var:

GDAL_DATA=C:\Program Files\GDAL\gdal-data

UPDATE 2011-10-07: About the GDAL Python bindings

After installing GDAL core components, you must install the Python bindings separately. You can use this installer (for Python 2.7 and GDAL 1.8.0), or grab one of the executables existent at

Depending on your Python installation, you can choose GDAL-1.8.1.win32-py2.6.‌exe, GDAL-1.8.1.win32-py2.7.‌exe, GDAL-1.8.1.win32-py3.1.‌exe or GDAL-1.8.1.win32-py3.2.‌exe

UPDATE 2011-03-25: Alicia Duarte, from IDESF, told me she was to additionally set the next enviroment vars to make it work:

GDAL_DRIVER_PATH=C:\Program Files\GDAL\gdalplugins
PROJ_LIB=C:\Program Files\GDAL\projlib

WARNING: This directory (GDAL Python bindings location) may not exist in your GDAL installation. In my case, the bindings are in C:\Python27\Lib\site-packages\osgeo, and I didn’t need to define this variable.

PYTHONPATH=C:\Program Files\GDAL\python

UPDATE 2011-07-19:  I think I introduced some confusion in the comments. I apologize for that. Several people are having problems with GDAL Python bindings. I’ll  try to make it clearer:

  • On one hand, there’s a sure thing: you need GDAL library + GDAL Python bindings installed in your system. There’s an easy way of doing it, by executing the generic installer: gdal-18-1310-core.msi. This installer includes the Python bindings, and they’re installed at C:\Program Files\GDAL\python directory by default. This should be enough.
  • If you previously have a Python interpreter and a GDAL version installed on your system (check it from a console, executing gdalinfo –formats), you may want to simply install the proper GDAL Python bindings. Let’s assume your GDAL version is 1.8 (lower versions won’t work with PostGIS Raster), and your Python version is 2.7. Then, you simply need to install GDAL-1.8.0.win32-py2.7.msi. This installer will put GDAL Python bindings at C:\Python27\Lib\site-packages by default. This is a different location than above, but at the end, you should have a working version of GDAL Python bindings on your system.
  • Finally,  the PostGIS Windows experimental binaries with PostGIS Raster support (step 4) are packed with their own version of GDAL library, used only by the raster2pgsql loader.

GDAL installed. Now, let’s go with step 3

Step 3: Installing PostgreSQL

I recommend Postgresql 8.4.x or higher. You can download the 1-click-installer from here, and install it in the common Windows’ way.

During the installation, you’ll be asked to install some nice additional stuff using the Application Stack Builder, like PostGIS 1.5.x or PostGIS 1.4.x. Don’t install anything. The PostGIS versions that can be installed doesn’t include PostGIS Raster. And you can’t install it separately, because, remember, now is part of PostGIS. We’re going to install last PostGIS version by hand. Don’t be afraid, it’ll be easy.

Step 4: Installing PostGIS

We’re going to use the PostGIS Windows experimental binaries. We need the binaries compiled for PostgreSQL 8.4, these ones

Once uncompressed, you can see this

postgis20 windows

Contents of binary package PostGIS 2.0 for Windows

Following the instructions of README.txt file, let’s edit makepostgisdb.bat to adapt the vars to our enviroment. We may want to change these vars:

set PGPORT=5432
set PGHOST=localhost
set PGUSER=postgres
set PGPASSWORD=password_of_postgres_user
set THEDB=template_postgis20
set PGBIN=C:\Program Files\PostgreSQL\8.4\bin\
set PGLIB=C:\Program Files\PostgreSQL\8.4\lib\

After that, we make a backup of our PostgreSQL bin and lib directories (PGBIN and PGLIB). Just in case.

We now execute makepostgisdb.bat. Take into account you may want to execute the script as administrator, in case your Windows user doesn’t have needed privileges (it was my case).

UPDATE 2011-06-08: For all Windows XP Professional SP2 users:

when you run makepostgisdb.bat from the binaries of POSTGIS SVN2.0, please rename the libiconv-2.dll in bin folder of Postgresql/8.4/bin folder to any other name. Now run the makepostgisdb.bat file. You will not get any error of “operation aborted …. transaction block” (Thanks to C Patnaik)

Once executed, we have PostGIS 2.0 + PostGIS Raster installed and configured. A new database called template_postgis20 is created, enabled with PostGIS and PostGIS Raster. Easy! Let’s test it with the next query:

select postgis_full_version(), postgis_raster_lib_build_date(), postgis_raster_lib_version()

And the result:

PostGIS version installed

PostGIS version installed

Of course, you can create your own database using template_postgis20 as template. From the command line:

createdb -U postgres -T template_postgis20 your_database

Or from pgAdmin III:

Creating new database from template in pgAdmin III

Creating new database from template in pgAdmin III

If you want to use the SHP2PGSQL GUI, you must copy the postguisgui folder (inside bin folder in the downloaded PostGIS experimental binaries file) into pgAdmin III folder (mine is C:\Program Files\pgAdmin III\1.12) and add the next lines to plugins.ini file, inside pgAdmin III folder too:

;PostGIS shp2pgsql-gui (Windows):
Title=PostGIS Shapefile and DBF loader
Command="$$PGBINDIR\postgisgui\shp2pgsql-gui.exe" -h "$$HOSTNAME" -p $$PORT -U "$$USERNAME" -d "$$DATABASE" -W "$$PASSWORD"
Description=Open a PostGIS ESRI Shapefile or Plain dbf loader console to the current database.

After that, you can use the GUI inside pgAdmin III:

SHP2PGSQL GUI installed under pgAdmin III

SHP2PGSQL GUI installed under pgAdmin III

Now you can load raster data into your database in 2 steps. In the first step, you will generate a SQL file. Open a command line and execute this:

python C:\Program Files\Postgresql\8.4\bin\ -r image.tif -t tablename -o image.sql

As result of this step, a SQL file named image.sql will be created in the directory where you executed the Python line above.

In the second step, you’ll need to load the SQL file in your_database, by using your favourite PostgreSQL client. For example, pgAdmin. If your use the psql command line client, the line to execute is:

psql -h localhost -U postgres -d your_database -f image.sql

If you want to translate your raster data from the database to image files at disk again, execute gdal_translate.

gdal_translate PG:"dbname=your_database user=postgres table=your_table mode=2" your_file.tif

Basically, this is all what you need to work with PostGIS Raster in Windows. Anyway, take into account the next additional notes:

Additional notes:

In step 2, I installed the whole GDAL library, including binaries and Python bindings. In step 4, I installed PostGIS 2.0 with all its pre-requisites. One of them is GDAL. The optimal way would be to use the existent GDAL library, but we’re working with pre-compiled binaries and DLLs. So, we have 2 copies of GDAL library:

  • C:\Program Files\GDAL\gdal18.dll: Installed with generic installer for GDAL, in step 2. Used by gdal_translate, when reading data from database, and in any operation involving GDAL, except the raster loading with script
  • C:\Program Files\PostgreSQL\8.4\bin\libgdal.dll: Installed with PostGIS Windows experimental binaries, in step 4. Used by script, to load raster data into PostgreSQL.

Both library files were compiled from GDAL 1.8.0 from trunk. But they will be slightly different, for sure. This is a suboptimal solution, of course, but it shouldn’t cause problems, because libgdal.dll is only used when loading raster data into the database. The rest of operations involving GDAL will be executed linking with gdal18.dll

If you want to translate the raster data to any image format different from TIFF, you can use the -of option in gdal_translate. For example:

gdal_translate -of "PNG" PG:"dbname=your_database user=your_user password=your_password table=your_table mode=2" your_file.png

To get available raster formats:

gdalinfo --formats

UPDATE 2011-06-11: I changed the gdal_translate line. I’m using the ‘postgres’ user and the ‘trust’ method to authenticate this user (so, no password is needed), but it’s only a simplification. In general, you should use a different user and a password-enabled authentication method, like md5. Thanks to C.Patnaik again, because his comment remainded me this issue


It’s possible to work with the last version of PostGIS Raster and GDAL PostGIS Raster driver in Windows, but assuming that:

  • You’re using experimental build. Not recommended for production enviroments.
  • The previous versions of PostGIS Raster (WKT Raster) and GDAL PostGIS Raster driver (before GDAL 1.8.0) are discontinued. Don’t use them.
  • It’s a suboptimal solution, because you install 2 copies of GDAL library. But I think this is the best available solution right now.

Do you have problems, something to add, modify or correct? Let me know it in the comments

    it give me that error

    “ImportError: No module named osgeo”

    when i run

    please help

    • March 28, 2011 12:32 pm

      That error is caused because the GDAL Python bindings are not properly installed. Execute python from a console and try this:

      >>> from osgeo import gdal

      If you get an error like:

      Traceback (most recent call last):
      File “”, line 1, in
      ImportError: cannot import name gdal

      You have to install GDAL Python bindings. Do it following instructions in step 2, by using the GDAL generic installer for core components. Choose the “complete” installation or the custom installation, if you want to manually choose the components to install. In that case, be sure the last option (Python bindings) is selected.

      Let me know if you continue having problems.

    Sounds like your console is using a locale unsupported by Python. To help you, I should know the python version you’re running and the locale of your console. If you’re using Python 3.x, you should try executing this:

      You probably introduced a space before starting writing in python console. Simply call python interpreter from console and write this, with no spaces at all before or after the text:

    and thank you for your replay

  7. March 28, 2011 3:47 pm

    Ok, try with:

    import gdal

    instead of:

    from osgeo import gdal

    Maybe you’ve installed old-gen python bindings, because you chose an old binary version of GDAL.

    Did you install GDAL 1.8? It’s the only GDAL version that will properly work with PostGIS Raster

    Check if the template_postgis database has a table named “raster_columns”. This message seems to appear because the PostGIS Raster extension wasn’t properly installed in template_postgis. Strange.

    when i make new database and it’s tamplate is postgis20 it create
    2 schemas the first one “public”
    contain one table “raster_overviews”
    and the second schema called “topology”
    which contain two tables “layer and topology”
    and no tables called “raster_columns”.

  11. March 28, 2011 5:00 pm

    If you use as PostGIS binaries, the database template_postgis should be created with all the PostGIS and PostGIS Raster stuff, in only 1 schema (public schema). If it wasn’t created (I don’t know the reason), you can create it manually:

    Inside that zip file, there are several SQL files with all the functions and tables you need to activate a new or existent PostgreSQL database with PostGIS and PostGIS Raster. These SQL files are inside \share\contrib\postgis-2.0 folder.

    So, do these steps, from console:

    createdb -U postgres
    createlang -U postgres plpgsql
    psql -U postgres -f postgis.sql -d
    psql -U postgres -f spatial_ref_sys.sql -d
    psql -U postgres -f rtpostgis.sql -d

    Then, you’ll can load raster files in by using

    • March 31, 2011 9:20 pm

      Your PATH var should include more things. For example, if you open a console and put “dir” on it, you’ll get a directory listing. This is because the path to “dir” binary is part of PATH enviroment var.

      Open a console and put:


      You’ll get all your enviroment vars. PATH between them. You’ll have to see the complete path to GDAL binaries (I guess C:\Program Files\GDAL\bin), and the path to your gdal18.dll file (I guess C:\Program Files/opengeo/opengeo suite/).

      You can test if GDAL is correctly added to your PATH var by executing

      gdalinfo –formats

      in a console.

    the jpg size 1.45 MB it is converted in to one table with only one row is this correct?
    but i can’t see it on the map and there is no erorrs
    i changed the extent of the map but still nothing seen although it is added as a layer in the legend map!

    • March 30, 2011 6:53 pm

      The image is small, and one row is enough. No problem there.

      About the rest… Sorry, but I don’t understand you. You could execute raster2pgsql with no problems, and you’re trying to see the image in any kind of visualizator (web based?, geoserver?). Am I right?

      In that case, the problem probably is in another part, not in PostGIS Raster (the GDAL driver, if you’re using it, for example).

      You can borrow the OCI.dll file from any software installed on any Windows machine or get from a reliable site. Put this OCI.dll in the GDAL folder [I have also put in the PostgresQL folder] It works and it stops the gdal_GEOR.dll error too.

        Which of these do I need? I have python 2.6 so I thought it made sense to install “GDAL-1.8.0.win32-py2.6.exe” and “gdal-18-1500-core.msi”, but you mentioned GDAL would install to just “C:\GDAL” but it installed in “C:\Program Files\GDAL”. So now I’m not sure which PATH to set, etc.

        Thanks for the help,

      • June 13, 2011 5:39 pm

        Stevie, you should simply install “GDAL-1.8.0.win32-py2.6.exe”. This file installs GDAL at C:\Program Files\GDAL by default. As result of that installation, you’ll get C:\Program Files\GDAL\gdal18.dll. This is the GDAL library used in your system.

        Apart from this, when you install PostGIS 2.0 using PostGIS Windows experimental binaries, you get C:\Program Files\PostgreSQL\8.4\bin\libgdal.dll. This version of GDAL library is only used by the loader, to read raster data from disk. The rest of the operations involving GDAL use the previous GDAL library, installed in step 2 at C:\Program Files\GDAL

      Hello, sorry for taking so much time to response. I had some hard days.

      1.- You may try the “CREATE TABLE AS” command, to store the query results as a new table (check

      2.- The PostGIS Raster data visualization with graphical clients is still immature. See, “Displaying PostGIS Raster” section

      3.- Which kind of queries are you running? If you could provide an example directly to postgis-user list ( I think you would get some help.

      4.- See point 1. I think it applies here.

      5.- Mmmm… I’m not sure. You may use GDAL to abstract your algorithm from the raster source used. Anyway, I recommend you to ask this question in postgis-user list.

      Best regards

      Did you install the Python interpreter from What happens if you open a command line (cmd.exe), write python and hit enter key? It should show you the python interpreter.

      If you get an error instead, maybe you installed python only for a user of your machine, and you’re in another user’ session. I’m not a Windows user, but I think you should be able to install Python interpreter for all your machine’s users. I did it with Windows 7 for this tutorial.

      If you’re sure you installed Python properly and still get that error, you should try adding the path to Python interpeter (C:\Python26\python.exe in my case) to the PATH enviroment variable. You have instructions on how to do this:

    I’ve used your helpful steps to install python 2.2.2, numpy1.6,gdal18,postgres and postgis svn 2.0

    It worked as you said except for 2 cases: one was minor: in step 4, the bat file needs to be edited so that the xcopy commands are copying the files form postgis2.0 to postgres bin folders.

    but i havent quite gotten the raster support to work. when i try
    python “C:\Program Files\Postgresql\8.4\bin\” –help

    i get ‘no module named osgeo’

    should i try editing the and remove the osge reference? i do have various Paths defined as in your post, except
    – in step 2:PYTHONPATH=C:\Program Files\GDAL\python : i dont python under the GDAL folder
    -and mmy path to Python is set as C:\Python27 (not C:\Python27\python.exe)

        Don’t modify raster2pgsql. The ‘osgeo’ include is necessary to work. The problem is your system can’t find the GDAL Python bindings. The PYTHONPATH enviroment var must point to the directory containing these bindings (osgeo directory,,,, If you installed GDAL properly in step 2, you should see C:\Program Files\GDAL\Python directory.

        Anyway, if you installed GDAL in a different location, please check it. Run a search in your system for, or The directory containing these files is the directory that should be pointed by PYTHONPATH.

        As a quick test, execute the python console and simply write this:

        import osgeo

        What do you see? An error message? nothing?

    I installed GDAL from your link ‘generic installed for gdal core components’ which was gdal-18-1310-core.msi
    This installer installed GDAL under C:\Program Files (x86)\GDAL
    But it did not install a python folder under the above.

    And ‘import osgeo’ in a Python installer gives me an error like ‘…import error: no module named osgeo’

    Also, i searched for and on my machine- i found them under a different application on my machine (QGIS) under gdal-17 (which i guess is not what we want anyway for this exercise).

    Last, in your additional notes you refer to
    “C:\Program Files\PostgreSQL\8.4\bin\libgdal.dll: Installed with PostGIS Windows experimental binaries, in step 4. Used by script, to load raster data into PostgreSQL”
    In my case, I have
    C:\Program Files (x86)\PostgreSQL\9.0\bin\libgdal-1.dll

    I’m wondering if maybe i also have to install one of the other gdal?, namely
    GDAL-1.8.0.win32-py2.7.msi from the other link in step 2 i.e

    I have tried to follow the June 13th conversations but am still confused. Do i need to install BOTH gdal-18-1310-core.msi as well as GDAL-1.8.0.win32-py2.7.msi

      You may want to include the complete path to postgis.sql before.

        Silly question, but did you enter the Python console or are you writing that directly in the command line (cmd.exe)?

        Follow these steps:

        1.- Start –> Run –> cmd.exe
        2.- From command like (NOT entering python console) write this (or the equivalent with your paths):

        python C:\Program Files\Postgresql\8.4\bin\ -r torno.tif -t tablename -o image.sql

        (You may get an error because python.exe is not part of the PATH enviroment variable. Add the path to python.exe to PATH in that case)

        And don’t worry, I’m not a native english spoker 🙂

    Now succeded in binding GDAL on python, but i dont think this PostGIS Windows experimental binaries is running properly becuase it was saying some file can not be found while i ran it.
    The template_postgis2.0 it created does not have a raster column.
    I did not see any file like libgdal.dll in the postgres bin folder
    I only saw 2 schemas the first one “public”
    contain one table “raster_overviews”
    and the second schema called “topology”

    Please Jorge, how can i get this postgis2.0 working in my machine.
    Does it has have both vector geometry functions as well as raster?

    Thanks in advance.

    • August 29, 2011 4:49 pm

      About your question: yes, PostGIS 2.0 have both, vector and raster functions.

      About your problem, I assume you followed my instructions. So, let’s see how all pieces work. First of all, which version of GDAL, Python, PostgreSQL and PostGIS are you using? I mean the concrete exe name tou used to install each program.

      Now, perform these tests:

      GDAL: execute gdalinfo –formats or gdalinfo –version in cmd. If there’re no errors, we can assume GDAL is properly installed (check version is 1.8.x)

      Python: from cmd, execute python interpreter (simply write python and hit ENTER). If you see the Python command line, we can assume Python is properly installed

      GDAL python bindings: from Python command line, write: import gdal. And hit ENTER. If you get an error “ImportError: No module named gdal”, the bindings are not installed.

      PostgreSQL + PostGIS 2.0: Execute a PostgreSQL client (pgAdmin or psql) and connect to your template_postgis20 database (and tell me how many tables this schema has, and their names). Then, execute this query:

      select postgis_full_version()

      And paste here the information you get.

      If any of these steps cause an error, paste it here, as detailed as possible.

  36. Iyke permalink
    August 29, 2011 5:06 pm

    both gdalinfo-format or version and python are said not recognised as an internal or external operable programs or batch files.
    Could this be the problem?, but i called up python command line or the python GUI and typed ‘import gdal’ and it worked.
    Is really tiring!

    You must add the GDAL installation path (C:\Program Files\GDAL, I guess) to your enviroment variable PATH. Check the PostgreSQL bin path (C:\Program Files\PostgreSQL\9.0\bin) is in PATH too.

    And about PostGIS, the error tells me your database has not been spatially enabled. Delete the database “template_postgis20” and manually create it. Then, connect with it and execute, in order, the files:

    1.- postgis.sql
    2.- spatial_ref_sys.sql
    3.- rtpostgis.sql

    Thy should be in the directory created when you unzipped PostGIS Windows experimental binaries.

    After this, your template_postgis20 database should have the tables:

    – geometry_columns
    – spatial_ref_sys
    – raster_columns
    – raster_overviews

    becuase I discovered that when i run the ‘makepostgisdb’ file, nothing is copied from this postgis-pg90-binaries-2.0.0svn folder.
    Becuase it says File not found, 0 File copied.
    That means all the neccesary files that should be copied from that folder to postgres directory are not copied. Which are supposed to be copied in by this statements
    xcopy bin\*.* “%PGBIN%”
    xcopy /I /S bin\postgisgui\* “%PGBIN%\postgisgui”
    xcopy lib\*.* “%PGLIB%”

  42. August 29, 2011 9:08 pm

    Ok. So, the problem is your “PostGIS enviroment” hasn’t been set, and the DLL files are not found. Execute the BAT file from the command line, to see the output (not from the Windows explorer).

    Unzip the file wherever you want. The important thing is to execute the BAT file. Once unzipped, the files under ‘bin’ directory are copied to PGBIN, and ‘lib’ files are copied to PGLIB. Ensure these enviroment variables point to the right directories: the ‘bin’ and ‘lib’ directories of your PostgreSQL installation. Probably:

    – C:\Program Files\PostgreSQL\9.0\bin\
    – C:\Program Files\PostgreSQL\9.0\lib\

    And your welcome 🙂

    Jorge, please can you give me a little bit detail on this command line execution?.
    Because when i click Run as Administrator, it automatically executes it on the ‘black’ command line. Am really not too sure of what to do right now.

    • August 29, 2011 11:31 pm

      You need to run cmd.exe (the ‘black’ command line) in Administrator mode. So:

      – If you’re running Windows 2000/XP, open the file explorer and go to C:\Windows\System32. Locate cmd.exe, right click on it and select “Run as administrator”.

      – If you’re running Windows Vista/7, follow these instructions

      Once a command line is opened, go to the directory where the bat file is located. So, if you unzipped the PostGIS binaries at C:\postgis-pg90-binaries-2.0.0svn, write in command line:

      cd C:\postgis-pg90-binaries-2.0.0svn

      Then, execute the bat file, writing in the command line:


      You will see the bat execution option. If there’s a problem, an error will be raised. I recommend you to make a screenshot of the command line and paste it here.

    I have followed all your step to install postresql in my machine having OS windows 7 home premium.As such I installed python 2.7, related numpy extension(i.e.numpy-1.5.1-win32-superpack-python2.7), GDAL core and binding( GDAL-1.8.0.win32-py2.7)as well. I create the environment for GDALtoo. After that I install PostgreSQL 9.1 and PostGIS 2.0. Up to this everything is ok. I can create a table with a data type raster as well as geometry. Now the Problem in loading *.tif file using with command line. Error is as :

    Traceback (most recent call last):
    File “C:\Program Files\Postgresql\9.1\bin\”, line 34, in
    from osgeo import gdal
    File “C:\Python27\lib\site-packages\osgeo\”, line 21, in
    _gdal = swig_import_helper()
    File “C:\Python27\lib\site-packages\osgeo\”, line 17, in swig_impor
    _mod = imp.load_module(‘_gdal’, fp, pathname, description)
    ImportError: DLL load failed: The specified module could not be found.


    So here is the error in the first line of the file while importing gdal.

    Can you please give me idea regarding this problem.

      Your system can’t find the GDAL dll. It should be placed at C:\Program Files\PostgreSQL\9.1\bin\libgdal.dll

      Please check that file exists, and add C:\Program Files\PostgreSQL\9.1\bin to your system path (PATH enviroment var). Then check raster2pgsql again.

        Hello jorgearevalo,
        Thanks for your reply.
        In the place C:\Program Files\PostgreSQL\9.1\bin\ there is libgdal-1.dll instead of libgdal.dll. However I set the system path for C:\Program Files\PostgreSQL\9.1\bin and still not working. Shall I have to change libgdal-1.dll to libgdal.dll or not?

        with best regards,

      • October 10, 2011 11:06 pm


        Yes, change the name to libgdal.dll and test again.

        Best regards,

      Hi Jorge,
      Though I have install PostGIS 2.0, I think there was a problem in the installation of it thats why I am facing the problem mentioned above. Actually when I first run the makepostgisdb.bat it gave error even in copying file from Postgis unzipped folder to postgresql folder. Later I did first four step of makepostgisdb.bat file manually i.e. copied my self in the respective folder of postgresql. These are the following four steps

      xcopy bin\*.* “%PGBIN%”
      xcopy /I /S bin\postgisgui\* “%PGBIN%\postgisgui”
      xcopy /I plugins.d “%PGADMIN%\plugins.d”
      xcopy lib\*.* “%PGLIB%”

      And then I removed these four line and run the batch file with administrator and it runs with some error. When I connected the database with pgadmin I found only three table in postgis 2.0 templete and are:

      – spatial_ref_sys
      – raster_columns
      – raster_overviews

      where as geometry_column and geography_column appear in a views folder.

      So now I can create the raster and vector table using script by create command but facing problem in loading thats why my intuition is that there is problem in running the batch file.
      I though it might be security issue of windows 7 and even disable the firewall and antivirus and run the batch file from command prompt but still not working .

      Hope you can give me best solution.


      best regards,

        Mmm… not sure. I’m not a Windows user. Try starting a Python console and simply importing gdal module:

        from osgeo import gdal;

        Are you getting the same error?

    Maybe there are some changes in the latest Postgis 2.0.0 binaries, because it worked before, but now I’m getting the same error. I tried this with Postges 8.4 and 9.0, Python 2.6.6 and 2.7.1. No change. I’m getting the same error from Python console.

    • October 12, 2011 12:15 am

      Are you getting the GDAL error too?

      • Dimitar permalink
        October 12, 2011 12:18 am

        Yes, the same error like Deepak discribed it.

      • October 12, 2011 12:57 pm

        Try the same solution I’ve proposed to him: open a Python console and load the gdal module, if possible:

        from osgeo import gdal

        Hi Jorge,

        Earlier there was an error when I executed from osgeo import gdal from Python conlsole. I forgot to set C:\Program Files (x86)\GDAL\ to my PATH environment variable (I’m on 64 bit Windows 7). Now it works. Thanks!

    Hi Jorge,
    Yes earlier there was error on running the from osgeo import gdal . Then I again install binding and set again path variable now I can load raster via loader.

    But I would like share the problem in running makepostgisdb.bat file in windows .As mentioned in my earlier post while running batch file it still unable to copy the files from postgis bin, lib etc to postgresql bin , lib etc. I did manually these things and run the batch file by removing these lines.
    Yes I able to run now the batch but it runs with error and finally I obtained three table in templete_postgis20 folder as
    – spatial_ref_sys
    – raster_columns
    – raster_overviews

    where as geometry_column and geography_column appear in a views folder.

    Anyway,so far I have access some functions related to raster and they work well if I get error in some case of-course I remember you on that time. Thanks

    Another things I would like to know about the source code for raster datatype especially “geomval” how it construct. Do you have idea about it if yes can you please provide me the link for it . Thanks a lot.

    Hello dear Jorge,

    -I have a error message when i try to generate this SQL file (command line C:\Program Files\Postgresql\9.0\bin\ -r image.tif -t tablename -o image.sql ) :

    python : can’t open file ‘C:\Program’: [Errno2] No such file or directory

    -However, when i try to load sql file in my data base via command line (psql -h localhost
    -U postgres -d template_postgis20 -f image.sql), all seems ok and i have not error message.

    .According to my configuration and installation is ok?
    .How to load a sql file via pgadmin 3?

    Could you throw light for me please?

    Have a good sunday?

    Laurent Celati.

      Hello Laurent,

      You should add C:\Program Files\Postgresql\9.0\bin to your PATH enviroment variable. Other way, you could change to that directory in your command line:

      cd “C:\Program Files\Postgresql\9.0\bin”

      And then execute raster2pgsql without the path -r /path/to/image.tif -t tablename -o image.sql

      But I’d chose the first option (add the path to PostgreSQL bin directory to PATH variable)

      To load a SQL file via pgAdmin III, you need to:
      1.- Open pgAdmin III and open a connection to your database
      2.- Click in the SQL button in the menu bar
      3.- In the new Window, choose “Open” and select your SQL file
      4.- Once the file is open, Click on the “play” button (or hit F5 in your keyboard). This will execute the sql file against your database, like psql does.

      Best regards,

        Thank you for your reply. i have suceed in generating and loading sql file in my databse.

        What is the next step ? How import raster file (tiff for instance) in my databse? Sorry if my question seems idiotic but i’m a thematic geograph and i ‘ m starting out with data base and postgis…

        Thank you to throw light for me.

      If you’ve loaded the SQL file generated by into your PostGIS Raster-activated database, you actually got it. The raster file you specified with ‘-r’ parameter is imported in your database.

      If you wanna see your data, check

      Anyway, the PostGIS Raster visualization is related with the GDAL PostGIS Raster driver. You can use it (GDAL 1.8.0 or superior. Check, but It’s under development. I’d love to devote more time to this task, and I’m actually working on it (until end of 2011, I couldn’t work on it harder). Stay tuned, because I’ll notifiy here when I finish a complete and stable version.

      And don’t worry about questions. I’m the first one with a looooooot of things to learn. I still consider myself as a ‘GIS n00b’ 🙂

    Dear Jorge,

    Everything seems fine with my install after I followed your tutorial. My setup is:

    Windows 7 64-bit
    Python 3.2.2 (64-bit)
    PostgreSQL 9.0 (32-bit)
    GDAL 1.8.1 (64-bit)

    I can successfully import shapefiles into my DB and view them in QGIS. My problem is with the function (I replaced the calls to “print” with “print()”, following python 3). When I run (with no line break):

    >python “C:\Program Files (x86)\PostgresPlus\9.0SS\bin\” -r “E:\temp\p019r25_5t890906_nn4.tif” -t public.landsat -o “E:\temp\landsat.sql”

    I get this message:

    Traceback (most recent call last):
    File “C:\Program Files (x86)\PostgresPlus\9.0SS\bin\”, line 104
    0, in
    File “C:\Program Files (x86)\PostgresPlus\9.0SS\bin\”, line 100
    3, in main
    gt = wkblify_raster(opts, filename.replace( ‘\\’, ‘/’) , i, gt)
    File “C:\Program Files (x86)\PostgresPlus\9.0SS\bin\”, line 945
    , in wkblify_raster
    summary = wkblify_raster_level(options, ds, options.overview_level, band_ran
    ge, infile, i)
    File “C:\Program Files (x86)\PostgresPlus\9.0SS\bin\”, line 897
    , in wkblify_raster_level
    hexwkb += wkblify_raster_header(options, ds, level, (xoff, yoff))
    File “C:\Program Files (x86)\PostgresPlus\9.0SS\bin\”, line 694
    , in wkblify_raster_header
    hexwkb += wkblify(‘B’, options.endian)
    TypeError: Can’t convert ‘bytes’ object to str implicitly

    Can this be due to the fact I’m using Windows 7 64-bit or is it something else I can’t think of?

    Thanks for helping me!

    Not so far I have found new cool tool to work with postgresql on win- Valentina Studio. Its free edition can do things more than many commercial tools!!
    I very recommend check it.
