In this article, we report on the vertical accuracy assessment of the WorldDEM\u2122, the latest global DEM using the synthetic aperture radar interferometry (InSAR) method, based on the German TanDEM-X mission data. For reference data we use vertical profiles along the centerline of 47 paved runways located in different areas around the world. Our accuracy statement is based on the analysis of discrepancies between the reference data and the corresponding vertical profiles extracted from the WorldDEM\u2122 dataset. Since the runways are nearly flat and have homogenous surfaces, the observed discrepancies are mainly due to instrument-induced error. Therefore, the derived accuracy statement has a universal character, e.g., it is not biased by other error sources including target- or environment-induced errors. Our main conclusions are that the WorldDEM\u2122 is the most accurate global DEM to date in terms of its vertical accuracy; it appears that the accuracy is spatially independent.<\/jats:p>","DOI":"10.3390\/rs8110934","type":"journal-article","created":{"date-parts":[[2016,11,10]],"date-time":"2016-11-10T10:51:39Z","timestamp":1478775099000},"page":"934","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":38,"title":["Evaluation of Vertical Accuracy of the WorldDEM\u2122 Using the Runway Method"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1532-9725","authenticated-orcid":false,"given":"Kazimierz","family":"Becek","sequence":"first","affiliation":[{"name":"Department of Geomatics Engineering, B\u00fclent Ecevit University, Zonguldak 67100, Turkey"},{"name":"Faculty of Geoingeenering, Mine and Geology, Wroclaw University of Technology, Wroclaw 50-370, Poland"}]},{"given":"Wolfgang","family":"Koppe","sequence":"additional","affiliation":[{"name":"Airbus Defense and Space, Friedrichshafen 88039, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6587-3417","authenticated-orcid":false,"given":"\u015eenol","family":"Kuto\u011flu","sequence":"additional","affiliation":[{"name":"Department of Geomatics Engineering, B\u00fclent Ecevit University, Zonguldak 67100, Turkey"}]}],"member":"1968","published-online":{"date-parts":[[2016,11,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Becek, K.
