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
• Wetlands
• 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.
