Abstract
Classification of agricultural land use is necessary to prepare the land use plans of a country, a district or a village. For this purpose, exploratory, reconnaissance, semi-detailed and detailed surveys are undertaken. Remote sensing techniques like aerial photographs and satellite imageries provide useful information on different scales and assist in monitoring the present land conditions. A case study of Nera watershed presented shows the utility of aerial photographs in the preparation of land husbandry units map on 1:50,000 scale.
LANDSAT data have been used in the delineation and mapping of soil salinity. Two degrees of soil salinity can be differentiated using computer-aided multispectral data analysis system. A study of landsat scene 158-040 shows the areas affected by the various soil degradation processes.
