Satellite synthetic aperture radar data-capability and prospects

Satellite-based radar systems have been collecting data of the Earth´s surface for some time. Prominent in this area are the ERS series of satellites, operated by the European Space Agency (ESA), which have been imaging the world for over five years. Within this period, many potential applications of the data have been found but the full economic benefits of the sensor are still being realised. This paper explores a number of applications, with a particular focus on the mapping and monitoring of land features, where satellite radar systems have a future, both in terms of offering a unique source of information and a back-up where other, more appropriate, sources of data are available. In particular the author discusses agriculture, forestry, oil and gas exploration, urban mapping and development
