WaterMe was part of the June 2012 Humanitarian Accelerator group. Their project takes freely available satellite data and extracts information about the water in vegetation in order to track drought.
The NDWI, or Normalized Difference Water Index is a satellite index derived from Near-Infrared (NIR) and Short Wave Infrared (SWIR) channels. MODIS data from NASA provides information about NIR and SWIR levels, allowing WaterMe to describe the water content in plants. By plotting ten years of data onto an open mapping interface and creating a mobile API and SMS gateway, the team hopes to help farmers choose the best location for their crops, make decisions about irrigation, and adjust to the changing climates more easily. The tool will also help aid agencies predict and plan for longer term drought conditions.
