Theory and applications of object-based image analysis and emerging methods in wetland mapping

This chapter addresses object-based image analysis (OBIA) and other emerging methods for mapping wetlands using remotely sensed and ancillary data. This treatment includes an introduction to OBIA and decision tree techniques, a history of the development of OBIA methods in wetland mapping, and four case studies describing recent wetland mapping research conducted in the Remote Sensing and Geospatial Analysis Laboratory at the University of Minnesota. The chapter ends with a discussion of lessons learned and possibilities for future applications.
