Building Precise Maps with Disser →

The folks at Conveyal have come up with Disser, a very useful command line tool written in Java that disaggregates numbers assigned to polygons based on more-fine grained geometries. The example they use in their blog post is disaggregating the number of people in a census tract using building geometries to get an estimate of the number of people living in a building. This can even be done based on combination of attributes of the buildings, such as the ration between total square footage and residential square footage (since people usually don’t live in offices or auto repair shops).
