Abstract

Quantification of the distribution and activity of shallow water vegetation is important given that such vegetation provide a variety of ecosystem functions and services. We estimated the distribution and coverage of seagrass patches using both GIS and high-resolution multi-band satellite imagery. The estimation accuracy of the distribution was greatly improved when field observation data were incorporated into the image analyses. However, supervised classification is greatly affected by "training data". Thus, it is still necessary to develop a valid method for the choice of "training data" in order to improve the analysis results.
