Presentation Transcript
land cover overview
Land Cover Overview
  • Map of surface type
    • Open Water
    • Grassland
    • Bare / Rocky
    • Forest
    • Urban / Developed
  • LandSat Satellite
    • Captures reflectance in 7 wavelengths
      • 0.45 – 2.35 µm
    • Main data source
self organizing map
Self-Organizing Map
  • The map is a standard 2D SOM, in a hexagonal configuration, 5x5
inputs
Inputs
  • Landsat Bands
  • Cartographic info
    • Elevation
    • Slope
    • Aspect (direction slope faces)
    • Distance from water (river / lake / ocean)
    • Distance from road
progress results
Progress / Results
  • Reflectance only
    • Average around 60%
  • Ancillary data
    • Average around 70%
    • Considering additional datasets which could be useful
  • Currently working on preprocessing the Landsat data more to improve accuracy.
