Identification of the key variables that can be estimated using remote sensing data and needed for Water Footprint (WF) assessment
Romaguera, M.; Toulios, L.; Stancalie, G.; Nertan, A.; Spiliotopoulos, M.; Struzik, P.; Calleja, E. J.; Papadavid, G. (2014)Accurate assessment of water use is an important issue in a globally changing climate and environment, where water is becoming a scarce but essential resource. The concept "?Water Footprint (WF) of a crop is defined as the ... -
Investigation of spatial relationships between crop coefficients and specific ground based vegetation indices for Karla watershed, Greece
Spiliotopoulos, M.; Loukas, A.; Mylopoulos, N.; Toulios, L.; Stancalie, G. (2014)The objective of this work is the investigation of the specific relationships between actual evapotranspiration based crop coefficients and vegetation indices adapted to Karla Watershed, central Greece. Surface Energy ... -
Potential of using satellite based vegetation indices and biophysical variables for the assessment of the water footprint of crops
Stancalie, G.; Nertan, A. T.; Toulios, L.; Spiliotopoulos, M. (2014)Satellite remote sensing techniques play an important role in crop identification, acreage and production estimation, disease and stress detection, and soil and water resources characterization because they provide spatially ... -
A spatial downscaling procedure of MODIS derived actual evapotranspiration using Landsat images at central Greece
Spiliotopoulos, M.; Adaktylou, N.; Loukas, A.; Michalopoulou, H.; Mylopoulos, N.; Toulios, L. (2013)In this study, the Surface Energy Balance Algorithm for Land (SEBAL) was used to derive daily actual evapotranspiration (ETa) distributions from Landsat and MODIS images separately. The study area is the Lake Karla basin ...
