The potential of Landsat images for studying sand dunes’ topography Academic Article uri icon

abstract

  • ABSTRACT We show that shading effects assessed by Landsat can be treated as a signal that stores important topographic information, especially when the spectral characteristics of a surface are homogenous. The coastal transverse dunes of the Ashdod area, and the desert linear dunes of Nizzana (both located in Israel), were selected to investigate the abovementioned idea. An innovative method for extracting slope, aspect, and height data for sand dunes using Landsat TM and ETM+ images was developed, based on the regularity …
