Addresses for geographical Data, ESRI-Shapefiles and other SQL Server geographical related stuff
Jun 10th
SQL Server 2008 R2 Reporting Services supports the visualization of geographical data in 3 ways.
- Datasets, based on the built-in .Net System-datatypes “geography” and “geometry”, which have been around since SQL Server 2008
- via built-in maps – but only for the United States
- via ESRI-Shapefiles, which one has to provide on his own
Now, where can you get those Shape-files?
Other, than in the USA where gathered data belongs to the people, with no cost (Census Bureau Geography), in other countries, such as in Germany, it is by far not easy, to even get such datat all.
In the following, I am collecting internet-sites, where one can find geographical data. I'd be happy to include more URLs, if you found a good one, to share.

Geocoding
The other option to show geospatial data in Reports, is to just use plain geometry/geography data. Here are some resources that help in getting access to such and/or converting/”geocoding” data:
The Google Geocoding API

Rob Farley shows how you can geocode you address-data using bing-maps and powershell:
