Can a land use map be related to a satellite image, a timely indicator of land use? Yes, but because digital data are collected and stored in different ways, the two data sources may not be entirely compatible.

SWAT simulations could be conducted based on two subwatershed configurations namely, dominant and virtual basin approach. The details of both approaches are given by Mamillapalli et al. (1996).
Image data from a satellite that has been interpreted by a computer to produce a land use map can be "read into" the GIS in raster format. Raster data files consist of rows of uniform cells coded according to data values.

combining a land use map with a map of flood prone areas to show potential residential areas at risk for flooding). Map analysis (often termed overlay or topological overlay) was one of the first real uses of GIS.
For example, the policy to "preserve farmland" used the town's land use map to identify farmland and then assign the areas as less suitable.
Raster map layers which contain very little information (such as boundary, geology, soils and land use maps) can be greatly reduced in size. Some raster map layers are shrunk to roughly 1% of their original sizes.
developed various different products to process satellite imagery from AVHRR, Landsat MSS, Landsat TM and SPOT imagery into land cover / land use maps, map deforestation, and assist in locating oil reserves.
