DGampe/TriangleMethod: Calculation of NDVI, LST and finally provide an estimation for actual evapotranspiration patterns using remote sensing data (default LANDSAT TM and ETM+ scenes).
The Triangle Method (Jiang & Islam, 1999) approach provides estimations for actual evapotranspiration using remotely sensed information as the Normalized Differnce Vegetation Index (NDVI) and Land Surface Temperature (LST). This package provides functions to derive those information from common LANDSAT TM and ETM+ scenes (might be modified by the user to work also for other sensors). The function 'triangle' then reads in these two grid-files (NDVI & LST) and allows to estimate actual evpotranspiration. Furthermore, the functions grid.plot provides a way to plot gridded data (as the final ETact, or NDVI etc.), based on the spplot-function and the package sp.
