Updating GDAL PostGIS Raster driver

August 25, 2012
tags: ,

Those past days, I’ve been working on the GDAL PostGIS Raster driver. I commited a version with relevant changes some days ago. It works with irregular blocking (tiles of different size), different pixel sizes in tiles and is pretty much faster than the previous version. Currently, I’m debugging to solve some errors, but I plan to have a stable version for next week. Of course, any feedback is welcome.

So, you can download the last GDAL nightly snapshot or checkout the code from svn repository. Also, I keep a github repository just for the driver’s code. Feel free to clone it, comment, collaborate or just say “Hi”

Apart from that, as this blog is now part of the OSGeo Planet, I’m going to update it way more frequently. For the time being, I can commit with one post per month. Probably more.

    Hey! Thanks for your efforts. I tried the gdal-svn-stable from 31.8.2012. Yet i still see no improvement from postgis raster driver in QGIS. Is this version the improved one, or im using the wrong one?

    Hmm, okay im fairly sure i used the correct gdal this time. The performance unfortunately is still unchanged. I cant even get it to work now (rasters load infinitely from postgis into qgis)

      Yes, you can send me the data to jorgearevalo at I suggest you to use a service like, or share a Dropbox folder with me (same e-mail address). And about using PostGIS Raster 2.0.1, no problem with that.

    Could you tell me if the gdal 9.2 released in October has the good and last (with updates)version of “Gdal postgis raster” ?

    In advance, thank you to throw light for me.

      No. The first stable version to include the last changes will be GDAL
      1.10, due to 2012/12/31.
