The Geological Application of Remote Sensing (GARS-) Programme is an international co-operation programme jointly sponsored by UNESCO and IUGS. It had been initiated 1983 with the aims (1) to demonstrate the use of advanced remote sensing techniques for the solution of key geological questions, (2) to ensure the transfer of information and technology through co-operative research in the field in combination with educational programmes and (3) to ensure wide dissemination of results. The project is currently in its third phase. The objectives of Phase 1 were to develop new methods for the integration of multisensor data to improve lithologic mapping in tropical environments (East-Africa). The objectives of Phase 2 were landslide mapping using GIS technology based on satellite data and new radar information on test sites in Colombia. The objectives of Phase 3 are to demonstrate the use of remote sensing, SAR in particular, for the analysis of volcanic and associate hazards in the Philippines. IUGS science policy asks for the promotion of new techniques in the field of earth sciences and to involve scientists from developing countries by training and technology transfer. The research is carried out with partner organisations in the specific countries mutually selected. During the current Phase 3 it is the Philippine Institute for Volcanology and Seismology (PHIVOLCS).
