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

comment Doubts about how pgRouting topology is built and how flexible it is
You're right. I've already changed, keeping the original questions at the end.

comment min function not found compiling osrm
I've installed boost 1.49 and later boost 1.55, but looks that boost 1.49 is first detected. And I didn't pass any argument to CMake

comment min function not found compiling osrm
That change caused a lot of "undefined reference to boost..." errors. I guess boost is not properly found (strange, because I ran a simple C++ code to show boost version and worked). Anyway, changing the sources in order to compile sounds odd for me. Thanks anyway.

comment How to export raster from PostGIS enabled DB as GTiff with gdal_translate
Ok. So, you stick with ogr2ogr. If you installed GDAL properly (and looks that you did, because PostGIS found it), ogr2ogr is installed. Probably at /usr/local/bin. Check if that path is added to your system's path. And ensure where ogr2ogr is with: sudo find / -name ogr2ogr

You don't need FWTools to use ogr2ogr if you compiled GDAL. It's included. You may need to add the path where the new GDAL installed the binaries (gdalinfo, gdal_translate, ogr2ogr...) to system path, if your problem is those commands are not found. About pgsql2shp, is not related with GDAL, and as long as I know, it's not packed with FWTools. It's a PostGIS tool. Which version of PostGIS are you using?

'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...

Thanks! I've updated the question. I'm closer now.

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

comment Create a band mask based on pixel locations, not in pixel values
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!

I was not familiar with it, but I'll check the link. Many thanks!
