20210831 12020900 1.0 TRUE Land Use Inventory The land inventory is based on several sources. Information is collected only in the City of Austin’s Full, Limited Purpose, and Extra-territorial jurisdictions, and not entire counties. The polygon geography is taken from appraisal district parcel layers. A land use inventory is performed by classifying land according to a coding system that reflects the primary improvements (buildings or structures) on each parcel. Most of the land use information is attached through a GIS Union from past land use inventories. Undeveloped parcels are checked against building permit, aerials, and appraisal records, generally collected during the fall of the previous year, or when data was made available.
