comment How to determine Parcel Neighbors?
This will need some topology-enabled GIS software for sure. So either PostGIS 2, GRASS (has topology, but not sure how to utilize it) or ArcGIS I suppose.

comment Count points inside polygons using PostGIS
As of PostGIS 1.3, ST_Intersection does implicit bounding box checks to utilize the GIST index. So I'm not sure how to enhance this...

comment Projection ETRS89 (Ellipsoid: GRS80) 6-Degree Zone 33 to UTM33N - WGS84
nhopton, your affine transformation basically was reprojecting them, so your solution is as valid as mine. Whatever works, I suppose? :)

Tried your code locally and it works. So, which version of GDAL do you have installed?

comment Postal areas for Germany? - Shape?
Arnulf did a nice job back then and as far as I can tell it's the only freely available dataset. But there are many changes , although minor, changes to the postal area geometries every year. But on a small scale you should be fine.

comment Can ArcGIS and OSGeo4W share the same python install?
I think I remember we had problems using the tools to generate topologies in geodatabases. But I am not sure anymore. Switching between arcgisscripting.create() and win32com.client.Dispatch("esriGeoprocessing.GpDispatch.1") made one tool work and another didn't anymore. Weird stuff.

comment What are some Free and Open Source GIS Desktop packages
qgis is nice, but the UI needs some more maturity... Using some of the plugins clutters the UI with tons of toolbars with icons I mostly don't understand easily. But then I am the GRASS GIS dude here in my department anyways...
