Saves time and money. Covers large areas at a low cost per acre. Existing wealth of spatial data collected from aircraft and satellite imagery can be integrated into a GIS and automated cartography. Can be used as a tool for more effective inventory and management of resources. Assists in field work by providing critical data for planning, sampling, and accurately locating field sites.
Multispectral capabilities provide information unattainable from any other source.
Provides cost effective methods for monitoring, change detection, and resource inventory. The type of imagery to use depends on the application. Satellite imagery has a lower resolution, but has multispectral capabilities and is ideal for studying large areas.
