f. Conclusions. HSI's advantages over aerial panchromatic
and color infrared include its
ability to automate data processing rapidly; this will be highly useful for change detection if
the hyperspectral data are collected over time. This data can then be easily coupled with
other useful GIS data when researchers attempt to combine hydrographic and wildlife data.
Wetland hyperspectral imaging paired with advanced data processing and analysis capabili-
ties were shown to be a valuable tool in supporting large-scale programs, such as the Com-
prehensive Everglades Restoration Program (CERP). For continued successful management
of the Kissimmee Restoration Project, the Corps' Jacksonville District and the South Florida
Water Management District will have to decide on a mapping method that provides the de-
tail needed to monitor plant community evolution while balancing this need with budget

6-4 Case Study 2: Evaluation of New Sensors for Emergency Management
Subject Area: Emergency Management.
Purpose: To test the resolvability of high-resolution imaging to evaluate roof
Data Set: Visible and infrared.
(1) Emergency response and management efforts are best facilitated with timely and
accurate information. Typically, these data include an enormous amount of geo-spatial in-
formation detailing the extent and condition of damage, access to emergency areas or sup-
port services, and condition of urban infrastructure. Remotely sensed imagery has the capa-
bility of delivering this type of information, but it is best combined with geo-spatial data
when they are rectified and pre-processed in a way that allows for easy visual and algorithm
analysis. The amalgamation of geo-spatial data into one comprehensive map will aid emer-
gency management organizations in their effort to coordinate and streamline their response.
(2) Understanding the utility and limitations of a sensor is highly valuable to emer-
gency response workers. This study evaluated the effectiveness of Emerge, a new airborne
sensor that collects visible and infrared radiation. Emerge was tested in relation to four pri-
mary requirements, listed below.
Ground sampling distance (GSD).
Capability for storing large volumes of digital data.
Pre-processing and the vendors ability to orthorectify up to "500 single frames of
imagery in 12 hours or less" and save these data onto a CD-ROM or ftp for fast
Indexing system for all resolutions collected, allowing for easy determination of
