Online maps for Oklahoma and Tulsa Counties are developed using ArcGIS Server for users to view road-centerline adjusted layers. These layers provide more accurate depictions of the real world based on spatially accurate (± 5 meters) aerial orthophotography.

All shapefile data provided by CSA is unprojected (Geographic coordinates NAD83) unless otherwise specified. For ArcMap 9.X users, download the projection file (.prj).
