Mapping DFAD FID Codes (2 of 2)
Spatial representation must be considered
Affects choice of EC
- FID = 180: Industrial Assoc. Structures (General)
- Point or Line =>
- EC BUILDING with EA BUILDING_FUNCTION = INDUSTRIAL
- Area =>
- EC BUILT_UP_REGION with EA USAGE = INDUSTRY
- Mapping is necessarily source-scale dependent (DFAD = 1:250k)
Affects appropriate use of EA(s)
- Point
- HEIGHT, WIDTH, LENGTH, ORIENTATION_ANGLE
- If the FID is round (e.g., a Flare Pipe) then WIDTH = LENGTH
- Line
- HEIGHT, WIDTH, DIRECTIVITY (to radar)
- Area
- HEIGHT, various density measures (roofs, trees, structures)
