SP-399 SKYLAB EREP Investigations Summary

FIGURE 2-4.

 

FIGURE 2-4.-A comparison of Landsat-, Skylab- (S190A and S190B), and aircraft-derived land use maps. This figure represents Level I and Level II categories mapped in the vicinity of Newburyport, Massachusetts. The land use maps illustrate the type of mappable units that can be derived from imagery obtained by using three different platforms and four different sensing systems. The land use classification system used was modified from reference 2-1. Specific colors represent Level I categories. Numbers represent subcategories, or Level II Informations, within the Level I categories. Hachuring is used in a few areas where positive identification could not be made for a single Level I category. The close correlation between specific-category patterns and areal extent on the Skylab S190B and aircraft maps should be noted. (a) Political map. (b) Landsat color-composite land use map. (c) Skylab S190A color-infrared land use map. (d) Skylab S190B color-infrared land use map. (e) Aircraft color-infrared land use map.
