The building-footprint dataset behind a building count on a Location (building-count extension). Counts from different datasets are not comparable — each dataset has its own date, detection method and confidence threshold — so every count names its source.

This Code system is referenced in the content logical definition of the following value sets:

This case-sensitive code system https://icr.healthcampaigns.org/CodeSystem/icr-building-source-cs defines the following codes:
