| City of San Antonio & Bexar County, Texas

Supporting Local Government AERO-METRIC Minneapolis Division produced 0.5-foot color digital orthophotography for the City of San Antonio and Bexar County, covering 1,440 square miles. 1"= 800' photography resulted in 5,000' x 5,000' tiled imagery. Enhanced overlap photography over downtown San Antonio minimized effects of “building lean.” The existing DEM, created two years prior for the Bexar County Appraisal District, was updated, and our proprietary orthorectification software and OrthoVista, were used to produce 1,550 ortho-tiles in TIF format as well as MrSID tiles based on a quarter-quad layout.

The city will use the deliverables to support their GIS program and to update their engineering database. The county Appraisal District will use the results for tax parcel assessments. AERO-METRIC’s "work considerably exceeded our expectations for the City and for our community. In fact, they did such a good job in raising the bar that users will expect to see the same level of quality in the future. They definitely went beyond the call of duty." —Joe Chapa, Assistant Director, City of San Antonio, Information Technology Services
