Remote sensed data from airborne an

Remote sensed data from airborne and space borne sensors provide a
significant source of spatial information for the national medium/large scale
topographic and land cover maps. Despite the obvious benefits and seeming
ease of mapping using these techniques, they remain underutilized by the small
islands due to mainly the high costs and the required specialized personnel and
equipment. Unmanned Air Vehicle (UAV) provide a viable and affordable
alternative, especially for small area coverage. When compared to conventional
satellite and airborne imaging, unmanned air systems have the advantages of
providing more flexible, rapid, efficient, and weather independent data
acquisition.
