Digital Elevation Models (DEMs) are a valuable resource in geoscience and remote sensing. However, not all DEMs demonstrate the same level of accuracy, resolution and precision.

Abstract

Digital Elevation Models (DEMs) are a valuable resource in geoscience and remote sensing. However, not all DEMs demonstrate the same level of accuracy, resolution and precision. Moreover, in some regions of the globe coverage is either sparse or non-existent, for example at the poles where ice also hampers accurate readings. In this paper, we propose to use collective archives of geo-located landscape photos acquired at ground-level to correct, validate and possibly reconstruct DEMs.
