dc.description.abstract | Creating consistent supervised vegetation classifications in different countries where training data are of different levels of quality and detail is challenging but important. For example, mapping steppe types and degradation of Mongolia and Inner Mongolia Autonomous Region (IMAR), China, using the same classification scheme would be helpful for doing comparative studies between the two regions and acquiring a better understanding of how country level differences affect vegetation on the Mongolian Plateau. Steppe and degradation maps, created through on-screen digitizing that combined image and ground information as input, were available in IMAR but not in Mongolia. We explored supervised classification using Random Forests (RF) to identify a reasonable sampling and training strategy and applied identical methods to classify remotely sensed images (Landsat Thematic Mapper 5) in IMAR and Mongolia using the same classification systems for the two countries in three ecological regions (meadow steppe, typical steppe and desert steppe). A number of challenges limit our ability to extend classifications trained in IMAR to Mongolia for creating consistent vegetation maps. | en_US |
