City data analysis

Hi,

I need to read the data for a city (Berlin) and to calculate average
building data.

The city is to be divided into several rectangles. I need the
distribution of building heights in every of these
rectangle. Furthermore, I want to calculate the average street and roof
width and the ratio of buildings to the rest (eg parks).

I may get EBDS (a German file format), a shapefile or DXF. What would
you prefer to work with? Do you know any software that would help me?
I am aware of the fact that I probably have to write the software
myself. I prefer C or Fortran 95.

Thanks
Sebastian

This can be done in ArcGIS as far I see . First you may import the
shapefile, or DXF data into ArcGIS.
Get a new polygon layer and draw the rectangles over the city of your
desired measurement.
Then you can use intersect tool to get the rectangles (polygons)
separately .

Once you have them you can work in each rectangle , by using SQL
query to get the distribution of heights ,
avg street and roof width etc.

Good luck

better suited for spatial analysis...
