DEM Application Analysis in the Aeronautical
Survey Program is an ongoing process. Research is currently being done
in the following areas:
-
Development of high-accuracy digital surface
models (DSMs) from NGS aerial photography or other remote sensing technologies.
-
Investigation of techniques for utilizing
obstruction data collected in the field to update elevations in the DSMs.
- Comparison of digital
photogrammetry, hyperspectral, and
LIDAR data for airport obstruction analysis.
-
Creation of simulated runway approaches ("fly-throughs")
as an aid to planning and field survey personnel.
