Remaining pervious features are created from heads up digitizing using 2012/2013 Orthoimagery and 2012 Lidar where Orthoimagery is not available. 2012/2013 Orthoimagery collected by Sanborn Mapping Company for the GeoMap consortium. The source imagery used was 6-inch, natural color with an accuracy statement of horizontal positional displacement within +/-3.33 feet of well-defined ground features; accuracy is based on ground control and DEM data. The accuracy statement does not apply to vertical surface features, such as structures, appearing in the digital orthophotography due to inherent lean. This product has been produced by the Communications and Technology Department for the sole purpose of geographic reference. No warranty is made by the City of Austin regarding specific accuracy or completeness.
