Within the PROgramme for a Meteorological Information System (PROMIS) project in Sweden a method of multi-spectral analysis and classification of Advanced Very High Resolution Radiometer (AVHRR) data is developed. The model will be based on a statistical database of object classes and ruled by information about prevailing Sun elevations and air mass temperatures. A new system provides the image processing and data handling capacity necessary for an operational classification of AVHRR data. Operational tests will start during the beginning of 1988.
