Detecting Small-scale Topographic Changes and Relict Geomorphic Features on Barrier Islands using SAR
The shapes and elevations of barrier islands may change dramatically over a short period of time during a storm. Coastal scientists and engineers, however, are currently unable to measure these changes occurring over an entire barrier island at once. The Bureau of Economic Geology and the Center for Space Research is hoping to overcome this problem by developing the use of interferometry from airborne synthetic aperture radar (AIRSAR) to measure coastal topography and to detect storm-induce changes in topography.Multisensor Classification of Wetland Environments using Airborne Multispectral and SAR Data
Several approaches which utilize information from both multispectral and SAR sensors are investigated for classifying the landcover in these data sets. Differences in statistical characteristics of the data necessitate individual parametric models for observations from each sensor, so data are initially classified separately, then a final classification is obtained by combining results from the statistical models using different multisensor integration techniques. These integrated results are compared to single-sensor classification results, as well as to a multisensor classification based on artificial neural networks.
