Mosaicking of Digital Elevation Models derived by SAR interferometry
Mosaicking Digital Elevation Models derived SAR interferometry
2016/5/20
In the framework of the Shuttle Radar Topography Mapper (SRTM) Mission the generation of high-quality Digital Elevation Models (DEMs) with global coverage of the earth's surface is envisaged. In this ...
Development & assessment of the global land one-km base elevation Digital Elevation Model (GLOBE)
Environmental variables Global Database Topography
2016/5/20
The Global Land One-kilometer Base Elevation (GLOBE) digital elevation model is the most thoroughly designed, reviewed, and documented global digital elevation dataset to date. GLOBE was developed by ...

Elevation Digital Elevation Model Topography Global Generalization
2015/12/18
Global digital elevation models are routinely used in a variety of earth science applications. GTOPO30, a widely used global elevation model produced by the U.S. Geological Survey, was produced in the...
A Framework for the Fusion of Digital Elevation Models
Multi-source data Fusion Integration Quality Control Spatio-temporal Digital Elevation Model
2015/12/3
In recent years, collection and processing techniques for Digital Elevation Models (DEMs) generation have improved rapidly, allowing surfaces to be represented with more detail and accuracy. Fusion of...
Elevation-Controlled Block Adjustment for Weakly Convergent Satellite Images
Orientation orthorectification georeferencing bundle adjustment rational function model
2015/11/23
In order to acquire the largest possible coverage for environmental monitoring, small overlapping for satellite images is often the case. Hence, the traditional 3-D bundle adjustment as used in photog...
CATCHMENT PROPERTIES IN THE KRUGER NATIONAL PARK DERIVED FROM THE NEW TANDEM-X INTERMEDIATE DIGITAL ELEVATION MODEL (IDEM)
TanDEM-X ASTER GDEM2 SRTM
2015/5/6
Digital Elevation Models (DEM) represent fundamental data for a wide range of Earth surface process studies. Over the past years the German TanDEM-X mission acquired data for a new, truly global Dig...
BUILDING DETECTION FROM HIGH RESOLUTION DIGITAL ELEVATION MODELS IN URBAN AREAS
DEM DTM frequency model estimation
2015/3/24
This paper describes an algorithm which aims at deriving digital terrain models (DTM) from dense digital elevation
models (DEM). This algorithm takes place in a processing chain for building detectio...
AUTOMATIC EXTRACTION OF TERRAIN SKELETON LINES FROM DIGITAL ELEVATION MODELS
Cartography Geomorphology Extraction
2015/6/1
Terrain skeleton lines, among the most significant elements of topographical maps, are the valley lines that connect the deepest
points of valleys, and the ridge lines that connect the highest point...
