I have now reprocessed the building outlines using a method to simplify them
while preserving their topology, an important consideration due to the large
number of row houses in Baltimore. This has produced much better results than my
previous simplification methods. After simplifying the data, the

Thank you everyone for the suggestions.
I had originally tried using QGIS's simplify function, but it simplified things
far too much, even with the minimum tolerance, and I had given up on
simplification. I tried ogr2ogr's simplify function due to the suggestion, and
it worked much better. This re

Hello,
The City of Baltimore provides a large amount of public domain GIS data through
their data portal [1]. Included are city wide building footprints [2], which I
would like to import into OpenStreetMap. Other users have already started
importing this data in a less automated way. I confirmed w
