Presentation Transcript

  1. Presentation for ECE539 Jason Mielens (mielens@wisc.edu) 12/12/08 Self-Organizing Maps for Land Cover Classification

  2. 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

  3. Landsat Band Examples

  4. Self-Organizing Map • The map is a standard 2D SOM, in a hexagonal configuration, 5x5

  5. Inputs • Landsat Bands • Cartographic info • Elevation • Slope • Aspect (direction slope faces) • Distance from water (river / lake / ocean) • Distance from road

  6. 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.
