Title:
Artefact detection in global digital elevation models (DEMs): The maximum slope approach and its application for complete screening of the SRTM v4.1 and MERIT DEMs 
Abstract:
Despite post-processing efforts by space agencies and research institutions, contemporary global digital elevation models (DEMs) may contain artefacts, i.e., erroneous features that do not exist in the actual terrain, such as spikes, holes and line errors. The goal of the present paper is to illuminate the artefact issue of current global DEM data sets that might be an obstacle for any geoscience study using terrain information. We introduce the Maximum Slope Approach (MSA) as a technique that u...    »
