L8 & DMC collects May 5, 2014

The DMC scene location/size randomness makes for better looking classifications overall

Land cover mapping abroad to improve agricultural survey sampling efficiency

Landsat 8 could finally make agricultural related land cover work in the developing countries a pragmatic option
