Experiences of application of satellite remote sensing in Sri Lanka during the last decade

Satellite remote sensing was first introduced to Sri Lanka in the late 1970s with the launch of the Landsat satellites. The author discusses the use of remote sensing for this country. Some of the topics discussed are: (a) in a well-mapped country is satellite imagery required? (b) cost of data (c) resolution of the data (d) timely availability of data (e) availability of cloud free data in the equator (f) digital equipment required and the maintenance of such equipment (g) the software required and the maintenance of it.
