| contents | In this article, we rationalize the need to develop a geomorphometric atlas of ice-free Antarctic areas. Geomorphometric mapping of such landscapes is necessary to obtain new knowledge about quantitative topographic characteristics of these unique objects and the further use of morphometric information in the geosciences. First, we present a concept, structure, and content of the atlas including a list of 194 areas to be modeled and mapped. For each area, the atlas will include the following materials: (a) a hypsometric map; (b) a map series of the eleven morphometric variables: slope, aspect, horizontal curvature, vertical curvature, minimal curvature, maximal curvature, catchment area, topographic wetness index, stream power index, total insolation, and wind exposition index; and (c) reference texts and tables. Second, we describe data and methods of geomorphometric modeling and mapping to be utilized for creating the atlas. Fragments of the Reference Elevation Model of Antarctica will be used as input data for geomorphometric calculations and modeling. Next, we discuss specificity of the ice-free areas posing challenges in the atlas development. Finally, we consider possible applications of the derived maps. The principal feature and novelty of the atlas will be the system view on maps of key fundamental morphometric attributes associated with the theory of the topographic surface and the concept of general geomorphometry. The atlas will concentrate multi-scale, multi-aspect quantitative information on the ice-free Antarctic topography, will present it in a systematized, organized, and easy-to-read form as well as will provide scientific and information support for research in Antarctica. |
