Tools for conflating and importing the Microsoft building data available at https://wiki.openstreetmap.org/wiki/Microsoft_Building_Footprint_Data .

Requires Python 3 and python-gdal with GEOS support. The R script requires R!

fetch.py

Retrieves current OpenStreetMap buildings from Overpass API. Takes an Overpass QL style bounding box and output file name as input:

python fetch.py 42.312,-83.096,42.386,-83.007 detroit_buildings.osm

stats.py

Calculates overlap between existing OSM buildings and Bing buildings. Input, in order, the osm building file, the bing shapefile and the filename to store the output in

python stats.py osmxml MSBuildingshp outfile

histo.R

Calculate a simple histogram from overlaps.txt

match.py

Finds OSM buildings with a large overlap with a Microsoft building and appends a height tag to those buildings.

python match.py osmxml MSBuildingshp outfile

newbuildings.py

Finds buildings in a Microsoft shapefile that do not overlap with existing OSM buildings and outputs a shapefile with simplified building geometries and suitable OSM tags.

python newbuildings.py detroit_buildings.osm /MS_buildings_michigan/ newbuildings

Example Session

Starting with the Microsoft data for Michigan stored in /share/gis/MS_buildings_michigan/.
