ABSTRACT
Demand for the world’s increasingly water supply is rising rapidly, challenging its availability for food production and putting global food security at risk. This aspect combined with climate change determine people to focus on all possibilities to obtain and preserve fresh water resources. In this context, data regarding evapotranspiration on earth, as significant part of water cycle in nature, are extremely valuable and important to know. This paper presents a way to create evapotranspiration maps for large territories, using remote sensed data collected by satellite, analyzed and processed with an improved algorithm, by a specialized toolbox, capable to be integrated in ArcGIS. The theoretically approach and results of the methodology are illustrated using the generation of Bulgarian evapotranspiration map as example.

Keywords: evapotranspiration, remote sensing, MOODIS, ArcGIS.
