Process description:
The mass point data were compiled using photogrammetric stereo-compilation techniques from aerial photography acquired in January 1996. This coverage is one of the topographic data sets compiled as part of the Tallahassee-Leon County GIS Inter-local 1996 Landbase Update Project.
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). The mass point data for the mspnt2 coverage was collected using the 1:8,400 scale photography. The base scale at which the data was captured was 1:1200. Mass points were located interactively by stereo compilers using DTM compilation standards sufficient for collecting continuous terrain data suitable for 2 foot contour mapping. Points were distributed as
necessary to accurately model variation in the terrain. The elevations in the digital data are stored to 3 decimal places and conform to National Map Accuracy Standards.
Modifications to Data Layer: None
Supplemental_Information
1. The dem96 topographic 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 where the ground was not visible to the stereo compiler, the mass point elevations should be treated with caution.
