Why not ask your question on the new OpenStreetMap Community Forum?


When is it appropriate for two buildings to share the same edge.

I am currently tracing building footprints from satellite imagery. If two buildings share a wall -- as in a row of townhouses -- would they share an edge on the traced footprint? What are some ways to distinguish whether buildings are actually connected or discrete units next to each other?

Thanks, Alyssa.

Most mappers will make building edges share nodes if they share a wall in reality, no matter whether these are structurally two independent walls touching each other, or a single wall. (Most mappers are not civil engineers.)

There's a plugin for the JOSM editor called "Terracer" that lets you draw the outline of a regular block of houses and then subdivide that into individual buildings.
