Evapotranspiration Mapping
Definition
Evapotranspiration Mapping uses GIS and remote sensing to quantify water loss through evaporation and plant transpiration. It is crucial in agriculture, hydrology, and climate modeling.
Application
Farmers monitor irrigation needs. Water managers balance supply and demand. Climate scientists model water cycles. GIS visualizes ET rates using MODIS, Landsat, or meteorological models like SEBAL or METRIC.
FAQ
1. Why is ET important?
It influences crop yield, drought prediction, and water resource planning.
2. Why is ET important?
From temperature, vegetation, radiation, and wind data, often via satellite models.
3. Why is ET important?
Google Earth Engine, ArcGIS, SNAP, and Python scripts with remote sensing libraries.
4. Why is ET important?
Agronomists, hydrologists, climatologists, and irrigation authorities.
