Visualization of a Digital Elevation Model

open access: yesData Science Journal, 2007
In recent years, Geographic Information Systems (GIS) have gradually changed from using the traditional 2D map expression to 3D visualization. The combination of visual techniques and GIS is a multi discipline, leading edge field, the development of ...

Digital elevation model and orthophotographs of Greenland based on aerial photographs from 1978-1987. [PDF]

open access: yesSci Data, 2016
Digital Elevation Models (DEMs) play a prominent role in glaciological studies for the mass balance of glaciers and ice sheets. By providing a time snapshot of glacier geometry, DEMs are crucial for most glacier evolution modelling studies, but are also ...

PROTOTYPE OF NATIONAL DIGITAL ELEVATION MODEL IN INDONESIA [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Although medium scale mapping has been done for the entire territory of Indonesia, there has never been a DEM unification to produce seamless national DEM. The main problem to generate national DEM is multi-data-sources.

A new digital elevation model of Antarctica derived from CryoSat-2 altimetry [PDF]

open access: yes, 2017
We present a new digital elevation model (DEM) of the Antarctic ice sheet and ice shelves based on 2.5 × 108 observations recorded by the CryoSat-2 satellite radar altimeter between July 2010 and July 2016.
