Applying Aerial Photography to Map Marsh Species in the Wetland of Lake Okeechobee

WithCaiyun Zhang

In Comprehensive Everglades Restoration Plan, vegetation information is mainly produced using high spatial resolution aerial photography through manual photo-interpretation techniques to inform the progress and effects of restoration on plant communities as well as others. This chapter presents a framework was presented to apply 1-foot aerial photography for mapping freshwater marsh species in the wetlands of Lake Okeechobee. Lake Okeechobee and its wetlands are at the center of the Greater Everglades. Marsh maps in the lake area are mainly generated through manual interpretation of large-scale aerial photography using stereo techniques. The reference vegetation dataset was from manual interpretation of the aerial photography collected in the project, which collected stereo imagery for using photogrammetric techniques in the interpretation procedure. Object-based texture measures from fine spatial resolution imagery have proven valuable for vegetation classification. For the pixel-based analysis, conventional kernel-based texture methods often utilize a fixed-size moving window over which to calculate texture measures for each pixel.
