Abstract
Potential and limitations of satellite laser altimetry for monitoring water surface dynamics: ICESat for US lakes
Highlights
Lakes and reservoirs are key components of regional and global water cycles, serving important roles in water resources management over human-dominated landscapes.September, 2017 Liu S, et al Satellite laser altimetry for monitoring water surface dynamics: ICESat for US lakes Vol 10 No.5 155 and watershed management activities in many regions of the world[3,4,5]
The overall objective of this study is to examine to what extent ICESat or more generally, satellite laser altimetry can be successfully used to measure water-level dynamics over time
The maximum difference between the two occurred at the boundary of the test area. This may be attributed to the exclusion of the Lidar DEM pixels outside the test area but covered by ICESat footprints
Summary
Lakes and reservoirs are key components of regional and global water cycles, serving important roles in water resources management over human-dominated landscapes. 2017 Liu S, et al Satellite laser altimetry for monitoring water surface dynamics: ICESat for US lakes Vol 10 No. 155 and watershed management activities in many regions of the world[3,4,5]. Given the ecological and environmental roles of lakes and other surface water bodies, there has long been a recognized need for monitoring their temporal dynamics[6]. Monitoring water level fluctuations, will help to track lake dynamics and correspondingly aid in better managing and conserving water resources[10]. Similar to other ground-based environmental monitoring technologies, a wide deployment of gauge stations is infeasible and can be hindered by many practical factors
