The Comprehensive Planning Act of 1989 provided for the development of a landcover database to be used in planning at state, regional, and local levels. The Georgia Department of Natural Resources (DNR) is currently developing this database by analyzing satellite imagery. This analysis involves the grouping of all spectral information into a desired number of landcover classes. Remote sensing the environment is becoming increasingly useful in natural resource management (Robinson and Nagel, 1990). The resultant landcover information can be useful to water resource management in a number of ways. Landcover maps showing the location and extent of wetlands will assist planners at all levels in guiding development in ways that will minimize adverse impacts to these valuable natural resources. Watershed and stream protection efforts can benefit from up-to-date landcover information that quantifies the location and areal extent of various landcover classes within the target watershed and surrounding areas. The potential exists for modeling patterns of water use based on hydrologic data and landcover information.
