DETERMINATION OF LAND-USE DYNAMICS IN A LAGOON WATERSHED BY REMOTELY SENSED DATA

Abstract

Extensive use of land and water resources results in changes in land-use and properties; wetlands are drained, reservoirs are built, settlements extend, and forests are converted to farmlands. Such changes affect the hydrology and ecology of a watershed. Further effects are pollution of the environment and deterioration of habitats. To follow the temporal change of land-use and corresponding properties, extensive laborious studies include data gathering from various state offices and field surveys. Remote sensing (RS) supported analyses, on the other hand, reduce the necessary manpower.
