TREE SPECIES CLASSIFICATION USING ERS SAR AND MODIS NDVI IMAGES
Forestry Land Cover Classification Fusion Optical SAR Multitemporal
2015/7/30
A set of ERS SAR and optical MODIS-images were classified to land cover and tree species classes. Different methods for pixel and
decision based data fusion were tested. Classifications of featurese...
THE CORRELATION BETWEEN NDVI VALUE AND SURFACE TEMPERATURE MEASURED BY ASTER
Atmospheric correction Land cover Vegetation Temperature Correlation
2015/7/29
The thermal environment in urban areas is characterized by the heat island phenomenon. To estimate the thermal conditions of land
surfaces by satellite, it is necessary to find the relationship betw...
