Foil 8 Satellite Imagery and Maps

From 3D Collaborative GIS in CIV Project Rome Laboratory CIV Final Review -- 9 April 98. by Marek Podgorny
1 Satellite imagery is 29 meters resolution multi-spectral coverage
  • We have purchased and processed 12 swaths covering entire New York state
  • The data contains 7 spectral bands, 3 visible, 4 infrared, that can be combined into color images
    • ER Mapper used to create color images for GIS viewer
    • "Special effects" can be obtained by mixing 7 bands in different proportions
2 Maps: problematic as there are no free data sources
  • DoD does not have good USA coverage (!)
  • Commercial raster maps acquired and processed
