Claim 0:
1. A method comprising, by a processing system:
extracting a timeseries of building representations for a geographic region from a timeseries of measurements of the geographic region;
determining relationships between the building representations;
determining a timeseries of building versions based on the relationships between the building representations, wherein each building version is defined by a set of temporally adjacent and substantially similar building representations; and
determining, a timeseries of changes between the building versions based on the respective building representation sets, wherein the change between a prior and subsequent building version is labeled as:
modified when the first building version shares building segments with the second building version;
replaced when the first building version shares no building segments with the second building version;
added when a prior building representation set represented no building and a subsequent building representation represents a building; or
removed when the prior building representation represents a building and the subsequent building representation represents no building.
