ABSTRACT
Emerging geospatial technologies such as unmanned aerial systems (UAS*) and light detection and ranging (LiDAR) coupled with structure-from-motion (SfM) photogrammetric processing present both opportunities and challenges for wetlands mapping. In spite of the plethora of aerial and satellite imagery that are readily available at a variety of scales and formats for wetlands mapping, the potential for UAS and other technologies to revolutionize mapping is gaining recognition from resource managers, scientists, surveyors, engineers, foresters, farmers, private practitioners, and policy makers (Anderson and Gaston 2013; Colomina and Molina 2014). This chapter explores these emerging and revolutionizing technologies.
