Digital Elevation Models (DEMs) are required for several tasks like generation of orthoimages, flood planning, erosion control, agriculture, generation of contour lines, visibility check, 3D-views and others. Mainly in developed countries DEMs are available, but not in any case like required. DEMs can be generated by traditional photogrammetry based on aerial photos if they are available and not classified, but also very often more economic by means of space images. Another possibility is the… 

DEM generation based on optical space images

Digital elevation models (DEMs) are a basic component for any GIS; in addition they are required for the generation of the most often generated photogrammetric product, the orthoimages. With the

Analysis of Digital Elevation Models Based on Space Information

Digital Elevation Models (DEMs) are a standard requirement for several applications. They are important as one source for the description of the terrain, but they are also required for the correct

Comparison of DEM Generation and Combination Methods Using High Resolution Optical Stereo Imagery and Interferometric SAR Data

Digital elevation models (DEM) from satellite data are generated mainly from two types of datasets using completely different methods: photogrammetry for optical stereo images (e.g. SPOT5, IKONOS)

DSM Generation from High Resolution Satellite Imagery Using Additional Information Contained in Existing DSM

Information about the shape of the Earth's surface are required for several tasks like the creation of orthoimages or flood control. The generation of digital elevation models (DEM) with stereo

Geometric Accuracy Evaluation , DEM Generation and Validation for SPOT-5 Level 1 B Stereo Scene

Against the preceding SPOT satellites SPOT 5 is generating images with a physical pixel size of 5m on the ground. This has improved the geometric and semantic possibilities by the factor 2. A SPOT

DEM GENERATION BY ASTER AND TK 350

Digital elevation models (DEM) have been generated by means of ASTERand TK350-images in the mountainous area of Zonguldak, Turkey. The automatic image matching of the ASTER-data did not cause any

DSM-to-LoD2: Spaceborne Stereo Digital Surface Model Refinement

A conditional generative adversarial network (cGAN) with an objective function based on least square residuals is trained to generate an accurate LoD2-like DSM with enhanced 3D object shapes directly from the noisy stereo DSM input.

Digital Height Models Generation by Means of Optical Stereoscopy and Interferometry – Case Study

Presently, Digital Height Models (DHMs) are used in a wide range of applications in many different domains: civil and industrial engineering, military, communications, navigation, environmental

DTMs generation from satellite stereo images: accuracy tests in mountain region

Quality tests results about DEMs obtained from ASTER data (15m geometric resolution) are shown, elaborated through commercial software, to understand which kind of applications can reasonably use these data.

Comparison of digital elevation models based on high resolution satellite stereo imagery

In this paper, we analysed and compared the digital elevation model (DEM) based on high resolution QuickBird and Pleiades satellite stereo images. 3D maps were generated for objects like trees near
