Quantitative Analysis of Anthropogenic Morphologies Based on Multi-Temporal High-Resolution Topography

Remote Sensing, 2019
Human activities have reshaped the geomorphology of landscapes and created vast anthropogenic geomorphic features, which have distinct characteristics compared with landforms produced by natural processes. High-resolution topography from LiDAR has opened

Improving the Accuracy of Global DEM of Differences (DoD) in Google Earth Engine for 3-D Change Detection Analysis [PDF]

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Digital elevation models (DEMs) represent the geospatial dataset core needed to model 3-D changes. The optimal dataset must be selected according to the environmental phenomenon under investigation as the offered resolution strongly affects the information level.

Volumetric change analysis of the Cauvery delta topography using radar remote sensing

Egyptian Journal of Remote Sensing and Space Sciences, 2022
Geomorphology refers to the study of the Earth’s physical land surface features. Digital Elevation Model (DEM) is a digital imagery where each pixel represents elevation value above or below mean sea level.
