Global Rangelands - Grassy Knowledge

This repository consists of two applications:

  • The calibration ipython notebook, that:
    • Takes a database of fractional cover field sites and extracts the reflectance data for the closest image acquisition in space and time
    • Follows the endmember extration method outlined in Scarth 2010 to build an optimal set of endmembers for image unmixing
  • The Earth Engine based appspot app
