I'm a software developer, focused on GIS. PostGIS and GDAL committer. I'd love to add 'where' to people's lives.

comment How to export raster from PostGIS enabled DB as GTiff with gdal_translate
'gdal-config --prefix' tells you the PATH where default GDAL library (1.6 in your case) is installed. Probably, $HOME/FWTools. You can get rid of that folder. Once done, the default GDAL should be 1.9. You may need to update your PATH variable, to ensure it doesn't contain references to the deleted FWTools folder.

OMG, absolutely. I've just fixed it. That was a silly and annoying mistake. Sorry for that.

As afalciano said, you can't use QGIS 2.0 yet. I didn't port the plugin to QGIS 2.0. I want to do it before the end of this year. And yes, you should use the last version of GDAL from trunk. It contains some improvements to PostGIS Raster driver.

Mmm... same problems. I've added my real data and the queries I've executed. So, if you want to try...

comment Create a band mask based on pixel locations, not in pixel values
Well, I guess it's time to learn how to use GRASS. BTW, many thanks!

I'm a novice in GRASS, but this looks like similar: grass.osgeo.org/grass64/manuals/r.clump.html

Wow! That looks exactly what I'm looking for. With which tool are you able to do it? QGIS? I assume that, but I can't see the option in QGIS 2.0.

comment What is a good way to retrieve geographic data along with imgs and mp3 files?
Ok, probably the mobile devices can handle a 100MB file as SQLite blob. My problem, as the backend guy, is that I don't want a 'dirty' solution. Currently, I create a json with relative links to mp3 and imgs, and this json, along with them, is zipped and sent to the user. It works, but I don't like it. I was thinking about an elegant format to store and retrieve img/audio/video files to a mobile client (MBTiles sounds elegant, for example)

comment Good algorithm to detect “wrong” features in a vectorial coverage
Sounds promising. Actually, next step of my work was to rasterize the vector data. I thought it would be easier to face this problem using the vector data, but I understand the logic of this solution. I just need to wait the funding to continue with this. Many thanks!
