for planning purposes. Examples of the environmental 
conditions that can be studied include landcover (vegetation 
type, amount, and condition), terrain elevation and related 
drainage patterns, and soil conditions (including near-surface 
soil moisture). 
The USDOE has made use of similar remote sensing surveys 
for the detection and potential identification of historically 
contaminated sites at nuclear materials production and 
processing sites (Blohm, 1994). Remote sensing has proven 
especially useful for the detection of undocumented buried 
waste sites (Brewster, et.al., 1994), hazardous material spills, 
and vegetation and habitat damage related to previous or 
ongoing operations. 
To take advantage of multisensor surveys, many analyses 
involve the use of a group of experts from several disciplines 
who collaborate to provide a more comprehensive 
understanding of a site's environmental conditions. Remote 
sensing expertise, specific application disciplines (e.g., 
hydrology, botany, or geology) and site knowledge all 
contribute to make a multidisciplinary analysis more 
meaningful. The combination of expert collaborations and 
the use of multisensor survey data has proven useful for 
several environmental restoration and monitoring programs. 
Another key element of the RSL multisensor survey program 
is the use of spatial data handling and analysis tools. Sensor 
data is collected and tagged with positional data provided by 
the Global Positioning System (GPS), which is used for both 
navigation and flight path recovery to index the remote 
sensing data. Image processing tools are also important to 
image registration and rectification, critical steps for 
multisensor data integration. Once integrated, spatial 
statistics, Geographic Information Systems (Christel et.al., 
1994), and 3D visualization tools are used to analyze and 
view the composite data.
