Remote Sensing

The USGS EROS approach to ET estimation allows the quantification of ET at two important scales: (1) field and (2) hydrologic basin. Field-scale ET is used for water use estimation to understand and quantify where, by whom, and how much water is being used in the landscape. On the other hand, basin-scale ET assists in understanding basin water balance and water availability.

Using remote sensing data, especially Landsat data to map cropland extent, and crop types, to support managing water supplies for both energy and food production to ensure global food security.
