Detection of Transition in Wetland Environment using GeoEye-1 Satellite Imagery

Abstract

Wetland monitoring with remote-sensed data is a key issue for planning appropriate wetland managements. We utilized an optical-satellite imagery with high-resolution to recognize where the transitions of dominant plants are appearing associated with the drying of the Senjyogahara-wetland. To infer the development of drying areas in the wetland, we adopted such an interpretation key as the growth in number of young trees and its direction of distributions on the satellite imagery, and obtained ground truth data in the study site relevant to the satellite imagery. The comparison between the satellite imagery approach and the ground truth investigations supported the effectiveness of using the interpretation key on the high-resolution satellite imagery to identify drying symptoms in the wetland.
