Coverage: Indonesia, 2000 - near-real time

Method:

State of planting and harvesting estimates were determined by importing MODIS Vegetation data into TIMESAT (http://web.nateko.lu.se/timesat/timesat.asp) – a program for analyzing time-series satellite sensor data. TIMESAT conducts pixel-by-pixel classification of satellite images to determine whether or not planting has yet begun. This process was followed for all of Indonesia over multiple years in order to evaluate current planting vis-à-vis historical years from 2001 - 2016. Check this blog post for more information.
