A wide variety of disciplines fall under the general category of earth and natural resource management. Geographical regions may cover both public and private lands in the form of:
- Forest holdings
- Oil and gas producing lands
- County, state and national parklands
- Wildlife preserves and refuges
- Riparian boundaries
- Coastal interfaces
It is often necessary to respond quickly to both natural and man-made events such as floods, tornadoes, hurricanes and wildfires, among others, to rapidly and accurately assess the extent of changes brought about by these events.
