Generalised building footprints at local resolution. The buildings have a unique identifier which can be used to style features distinctly. The identifier will not be persistent between product versions and therefore there will be no change history information for a feature.
Schema
The schema of the feature type describes the "returnables" and "receivables". "Returnables" are feature properties that are returned in responses to a query. "Receivables" are feature properties are feature properties that have to or can be provided by the client in mutation operations (create, replace, or update). Unless otherwise specified, a property is both a returnable and a receivable.
