摘要：Land use land cover maps developed for a particular region are very useful in estimating the surface characteristics and the various uses that are being carried out over the particular region. Geographic Information System (GIS) may be used to develop maps of such types with relative ease without actually conducting a large scale on site survey. Still GIS offers a relatively precise land use map for the required site. In case of a watershed, these maps may be used to assess the various crop patterns that are in use.
