Process step:
Process description:
Bridges were compiled using Photogrammetric stereo-compilation techniques and Aerial Photography acquired in January 1996. This coverage is one of the planimetric data sets compiled as part of the Tallahassee-Leon County GIS Inter-local 1996 Landbase Update Project. The primary contractor for this project was ADR Associates of Pittsburgh, Pennsylvania. The project was conducted in two phases. The phase 1 area is an irregular shaped area which includes the Tallahassee City Limits south to Woodville and the southern boundary of Leon County. The Phase 2 area includes the remaining portion of Leon County. The limits of the Phase 1 area are shown in the Arc/Info Coverage "Adrproject" under the system directory ":/edb/adrproject". The Phase 1 area was flown at an altitude of 4200 feet producing a nominal photo scale of 1:8400 (1" = 700 feet). The Phase 2 area was flown at a higher altitude of 8400 feet producing a nominal photo scale of 1:16,800 (1" = 1400 feet). Modifications to Data Layer: None Supplemental_Information 1. The base96 planimetric data sets should be used for applications compatible with 1:1,200 (1" = 100 ft)and 1:2,400 (1" = 200 ft) map scales. 2. In areas of dense tree cover, roads, buildings and other features will not be visible to the stereo compilers. Only those features visible in the aerial photography were mapped. Features obscured by tree cover or in heavy shadows may have not been mapped. 3. Roadway segments supported by pipes, box culverts, or cross drains were not mapped as bridges.
