The collaborative project to translate the QGIS 1.5 User Guide into Russian is nearing completion. I’m busy with the final editing and formatting.

Recently, I had to look into the OGC CSW (Catalogue Service Web) standard. It’s an interesting and useful thing, but most of the public servers I managed to find implement various aspects of it in a strange way :-(. So I have to add a monstrous construction to the code to catch exceptions and give the user a more or less understandable error message.

I am also slowly writing Pascal wrappers for the GDAL/OGR and Proj libraries. I couldn’t find any Pascal bindings for GDAL/OGR, so I’m making my own. I already have a more or less working module for OGR and some examples of its use. A module for OSR is also ready, but has not been tested yet. Next in line is a module for GDAL.

The situation with the Proj wrapper was a bit more interesting: first, I found a Pascal module for Proj 4.4.3 (the current Proj version is 4.7.0), and this wrapper required changes to the source code of the Proj library. I didn’t like this approach and started to make my own module, partly based on the one I found. Later, when updating the FPC compiler, I accidentally noticed that the available packages included modules for Proj 4.6.1. Now I’m not sure what to do: should I continue developing my own wrapper or not?

I plan to push the results of my work upstream, and if that doesn’t work, I’ll just publish them somewhere.
