Interwar Poland Political Districts Available

During the course of writing my thesis on interwar Polish census taking, I developed a number of geospatial basefile sets from scratch.  Considering how little of this work actually got into my thesis, I guess I'd have to call this a hobby.  The source map for everything was Mapa Rzeczypospolitej Polski (Map of the Second Republic of Poland). Warsaw: Wojskowy Instytut Geograficzny. 1934.  Anyhow years have passed and I see little point in just sitting on these things if anyone else has a use for them.  Drop me a line at paul@dziemiela.com if you are interested.  They are free for noncommercial uses. Most were developed for use in specific cartographic products so their usefulness will vary. 

I recently cleaned them up a bit for some folks and created a KML version you can view in Google Earth.

Here is an example of some of the 1931 census data
