Multisensor Classification of Wetland Environments using Airborne Multispectral and SAR Data
Area Description
Bolivar Peninsula is part of the low relief barrier islands of the Texas coast located at the mouth of Galveston Bay. The test site chosen for this study consists of a salt marsh located at a washover fan on southern Bolivar Peninsula.
For classification purposes, this salt marsh study area is characterized in terms of sub-environments defined by Bureau of Economic Geology Wetland maps. The various landcover types present in these environments include
- low proximal marsh,
- high proximal marsh,
- high distal marsh,
- spoil/barren flats,
- water, and
- trees

The low proximal marsh corresponds to tidal flats comprised of
Spartina alterniflora which experience frequent flooding. High proximal marsh is defined as more
continuous areas of Spartina alterniflora and Salicornia virginica and are less frequently flooded. High distal marsh is comprised of Spartina patens, Salicornia virginica, Juncus roemerianus and lies adjacent to barren sand flats. This area is flooded less frequently than proximal marshes.
