Spatial planning measures on state level rely on up-to-date and accurate geospatial
data and statistics. Aerial photography serves for regular revisions of existing
land use/ cover maps in order to provide localised and topical information on
recent territorial developments.
This geospatial information allows for GIS-based
cross-analyses with other geographic data, e.g. for the accounting of building
land, and helps to overcome well-known limitations of aggregated areal statistics.
