Paper will show an implementation of TVDI (Temperature-Vegetation-Dryness Index) algorithm on GPU (Graphics Processing Unit). Calculation of this index is based on LST (Land Surface Temperature) and NDVI (Normalized Difference Vegetation Index). Discussed results are based on multi-spectral imagery retrieved from AVHRR3 sensors for area of Poland, especially from region of Gdańsk coastal zone. All phases of TVDI implementation are modified in respect to GPU platform. Specific aspects of on GPU implementation will be compared with CPU implementation. At the end, time measurements of images processing will be shown and analysed. Also all technical means used to achieve mentioned result will be briefly presented.
