Hi, Can anyone suggest me how to estimate Evapotranspiration from Remote Sensing data using GIS and ERDAS softwares. And Which methodology is simple and accurate for Evapotranspiration estimation?
This will get you to the many papers by Richard G Allen and the METRIC model. It is the business. It has been updated as well, so some investigation will be necessary. For recent papers building on this see Justin L. Huntington . Can also look for a Google Earth Engine option there.
