� Clark Labs (Clark University) since 1987 (Prof.Ron Eastman)
� Idrisi is used for GIS lessons at the Faculty ofForestry since 1996 (Prof. Vladimír Židek)
� Idrisi Resource Center since 1997 (together withthe FF of the Technical Univ. Zvolen, Slovakia)
� 32-bit mainly raster oriented system, howeversupporting vector data format
� Image processing – mosaic, transformation,classification (including hyperspectral images)
� GIS analysis – distance and context operators, decision, statisticalmodules (neural network), time series, DMT → complex environmentalmodules
� Abu Abd Allah Muhammed al-Idrisi (1100 – 1166 n.l.)
