Abstract: The digital elevation model (DEM) provides important data support for geographic information analysis. However, due to the limitation of measurement cost and complex terrain, the collected ...
Digital elevation model validation with no ground control: application to the topodata dem in Brazil
Digital Elevation Model (DEM) validation is often carried out by comparing the data with a set of ground control points. However, the quality of a DEM can also be considered in terms of shape realism.
Abstract: SAR Interferometry (InSAR) has developed as a key method to derive Digital Elevation Models (DEMs). The large ICEYE fleet provides a unique source of data for the interferometric generation ...
