Self-Organizing Maps for Land Cover Classification


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


Landsat band examples

Landsat Band Examples


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.
