A Comparison of the performance of digital elevation model
pit filling algorithms for Hydrology.
Digital Elevation Models
(DEMs) are employed to reckon different geomorphological and morphometric parameters of watershed [4,5].
The development of geotechnology provides the procedures and techniques to assist in the analysis of landforms through modelling and interpretation of digital elevation models

On the right is a sub-meter digital elevation model
of the same area built out of documented satellite imagery and the Thales GeoMaker geospatial production suite incorporating accurate sensors models over verified map data.
Currently, a number of global DEM datasets are widely used, such as the global 30 arc s elevation dataset (GTOPO30), the Global Land One-km Base Elevation Project (GLOBE), the Shuttle Radar Topography Mission (SRTM3), the Altimeter Corrected Elevations 2 (ACE2), the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model
(GDEM), and the Global Multi-Resolution Terrain Elevation Data 2010 (GMTED2010).

The production of orthophoto and digital elevation models
(DEMs) became completely digital, mostly automatic and with short response of time.

Digital data of digital elevation models
(DEM) are needed to determine the slope stability factor (Acharya, et al., 2006).
The map, known as a global digital elevation model
, is an updated version of a map released in 2009.
