Multidirectional hillshade derived from the GIMP Digital Elevation Model, Greenland

This dataset comprises a multidirectional hillshade raster derived from the Greenland Mapping Project (GIMP) Digital Elevation Model. The hillshade was produced to serve as a semi-transparent overlay for cartographic applications, enhancing terrain depth and surface detail while preserving the original colour characteristics of underlying map layers.

The multidirectional illumination method reveals terrain variation from multiple light directions, providing improved representation of landforms compared to traditional single-direction hillshading. The dataset is intended for visualisation purposes in web maps and other cartographic products.

This data set consists of an enhanced resolution digital elevation model (DEM) for the Greenland Ice Sheet. It was constructed by combining ASTER and SPOT 5 DEMs over the ice sheet periphery and margin with AVHRR photoclinometry for the interior and far north, and calibrating the data to approximate mean ICESat/GLAS elevations from 2003 to 2009.

Statement

The multidirectional hillshade was derived from the Greenland Mapping Project (GIMP) Digital Elevation Model (Howat et al., 2014). The GIMP DEM provides surface elevation data for Greenland and forms the topographic basis for this visualisation product.

The hillshade was generated using a multidirectional illumination technique inspired by the cartographic principles of Eduard Imhof. Adjusted scaling suitable for large map extents was applied to enhance terrain variation across multiple scales. A colour ramp with intermediate transparency levels was combined with image processing techniques to preserve both terrain detail and underlying map colours, producing a semi-transparent cartographic overlay.
