Multisensor Classification of Wetland Environments using Airborne Multispectral and SAR Data
Multisensor Data Description
Two near concurrent airborne data sets were acquired over the study site for the purpose of mapping wetland vegetation. Both 20 MHz and 40 MHz AIRSAR data were acquired by NASA/JPL on June 28, 1996 with a ground resolution of approximately 8m and 4m respectively. Additionally, Calibrated Airborne Multispectral Scanner (CAMS) was flown by NASA/Stennis Space Center on July 3, 1996 with approximately 4m spatial resolution. The CAMS data and the 40 MHz AIRSAR data were selected for multisensor classification due to their common coverage and comparable spatial resolution.
The multisensor classification system analyzed data from three sensors: optical, thermal, and radar. The 'optical sensor' consisted of the six Landsat bands of the CAMS instrument (Blue-NIR) plus a vegetation index, the thermal sensor recorded the ninth band of the CAMS data, and the NASA AIRSAR system acquired two frequency bands (C,L) of fully polarimetric radar data (six channels total).
