Multispectral Change Detection Techniques Using Landsat Thematic Mapper Data and Airborne Data Acquisition and Registration (ADAR) Data Report, March 2002

To effectively manage conserved biological preserve lands, a land manager must map important biogeographic features such as vegetation structure and landform change over time and space, e.g., urban growth patterns and habitat disturbance. This type of mapping/analysis is traditionally done with frequent field visitations covering limited spatial and temporal extents. However, for San Diego County’s Multiple Species Conservation Program (MSCP) projected 98,379 acres of preserve in the initial sub area plan, the staff and time requirements, to perform comprehensive field visits is considered to be logistically impractical and economically unfeasible. An alternative approach to conducting large-scale landscape monitoring and change analysis is the use of remote sensing. With this approach a researcher can remotely detect and map surface variability temporally, spatially, and spectrally through the use of airplane or satellite based sensors.

The County of San Diego was awarded a Natural Community Conservation Planning (NCCP) Local Assistance Grant in the amount of $46,335 from the State of California Department of Fish and Game to look at how aerial digital imaging technologies, including ADAR, can enhance field mapping and monitoring in MSCP reserves in the County of San Diego. The County of San Diego partnered with Doug Stow of San Diego State University to evaluate the application of high-resolution digital imagery for comprehensively monitoring the status of habitat within the Lusardi Creek and 4S Ranch portions of the MSCP preserve.
