The Integration of Imagery, Elevation Models and Polygon Coordinate Files through a Common Map Base,
SCIENCE APPLICATIONS INC TORRANCE CA
Pagination or Media Count:
The purpose of this study was the integration of remotely-sensed imagery and cartographic data by reprojecting them to match a common map base with a Universal Transverse Mercator projection. The three data types were aircraft multispectral NS001 scanner imagery simulating the spectral channels of the Landsat-4 Thematic Mapper from visible to thermal infrared Digital Land Mass Simulator or Arc-Second digital terrain models and, land use polygon coordinate files created by Environmental Sciences Research Institute. Each of the data types had inherent resolutions and projections that were changed somewhat during the reprojection process. Techniques included control point selection from imagery and reference maps map base calculations based on the cataloguing and manipulating of control points with the Image Based Information System IBIS and spatial and each of spectral rectifications of the imagery and cartographic data using algorithms of the VICAR Video Image Communication and Retrieval image processing system.
