The management of National Forest land requires current and accurate natural resource information. The
USDA Forest Service uses a variety of remote sensing systems to provide resource managers the information
required to address National Forest management issues. Conventional 9"x9" large scale photography continues
to be the most common type of photography used in the field. Small scale high altitude aerial photography
is being used to prepare orthophoto maps, and to create and update topographic maps. The NASA ER-2 high
altitude aircraft and sensors such as the Large Format Camera, Optical Bar and Metric Mapping cameras are
used for forest pest management projects, and creating and updating resource inventories. In addition, the
Forest Service utilizes small format cameras (35 mm and 70 mm) and airborne video systems to provide low
cost, near real time imagery for monitoring applications.
The Forest Service also utilizes airborne electro-optical sensors such as Multispectral Scanners, Thermal
Scanners and SPOT and LANDSAT satellite imagery to provide large scale coverage for a number of resource
monitoring and inventory applications. The Forest Service has recently initiated a program to develop
procedures and methods for incorporating remote sensing information into GIS data bases.
