c. Archive Imagery. This can be accessed and purchased at a reduced rate. Some im-
aging systems can acquire new imagery at reasonable rates as well. It is now possible to
tailor acquisitions to meet the specific needs of Corps projects. Costs presented in this
manual will fluctuate, but generally become more affordable over time. The downward
trend in cost applies to all aspects of remote sensing - data acquisition and the required
software and hardware.
3-2 Corps 9--Civil Works Business Practice Areas. The spatial, spectral, and
temporal requirements set by the goals in a Corps business practice area should be bal-
anced with the economic limits of the project. To achieve this result, it is helpful to con-
sider a few preliminary steps when planning an image data acquisition. Below is a review
of the Corps 9 Civil Works Business Practice Areas. The steps that should be taken to
determine the specific data requirements follow each business practice. A list of vendor
services is presented along with details on the various platforms (airborne, satellite, and
ground penetrating radar). The nine business practice areas in Civil Works of the Corps
of Engineers and a listing of their operations follows:
Responsible for navigation channels.

Shore protection--protection from hurricane and coastal storms.
Construction of jetties, seawalls, and beach sand renourishment.
Responsibility for dam safety--inspection of Corps and other's dams
c. Environmental Missions.

larger Florida Everglades hydrologic restoration project.
