Digital elevation model (DEM) generation from stereo images is an effective and economical method in topography mapping. This paper used the stereo pair methodology to generate the digital elevation model (DEM) from PRISM (Panchromatic Remote-Sensing Instrument Satellite) sensor which is onboard of ALOS (Advanced Land Observing Satellite). The pair of forward-backward is used as stereoscopic im...

With the LIDAR data more wide use in DEM products, especially in urban area DEM modeling, the research on Grid DEM with LIDAR data is more and more urgent. Also users are more desired to acquaint themselves with LIDAR data, especially to know more about the accuracy of Grid DEM based on LIDAR data. Therefore, it is rather necessary to explore the matter of accuracy of DEM based on LIDAR data. I...

Cellular stress response proteins like Hsp70 may be affected by exposure to static magnetic fields (SMF). We examined whether exposure to a 100 mT SMF and GSH-depleting diethymaleate (DEM) would affect the levels of Hsp70 mRNA in HL-60 cells. Cells were exposed to SMF, DEM, a combination of DEM and SMF as well as 42oC. We found that only exposure to 42oC significantly affected the levels of Hsp...

discrete element method (dem) is extensively used for mathematical modeling and simulating the behavior of discrete discs and discrete spheres in two and three dimensional space, respectively. prediction of particles flow regime, power draw and kinetic energy for a laboratory or an industrial mill is possible by dem simulation. in this article, a new approach was used to assess the main paramet...

The DEM generalization is the basis of multi-dimensional observation, the basis of expressing and analyzing the terrain. DEM is also the core of building the Multi-Scale Geographic Database. Thus, many researchers have studied both the theory and the method of DEM generalization. This paper proposed a new method of generalizing terrain, which extracts feature points based on the tree model cons...

Im folgenden Beitrag wird die Zielsetzung des Projekts beschrieben. Es folgt ein Überblick über ausgewählte Rechtsprobleme aus dem Urheber-, Hochschulsowie Datenschutzrecht...

Image Registration implies mapping images having varying orientation, multi-modal or multi-temporal images to map to one coordinate system. Digital Elevation models (DEM) are images having terrain information embedded into them. DEM-to-DEM registration incorporate registration of DEMs having different orientation, may have been mapped at different times, or may have been processed using differe...

This study is focused on the evaluation of a Digital Elevation Model (DEM) for Tokyo, Japan from data collected by the recently launched TerraSAR add-on for Digital Elevation Measurements (TanDEM-X), satellite of the German Aerospace Center (DLR). The aim of the TanDEM-X mission is to use Interferometric SAR techniques to generate a consistent high resolution global DEM dataset. In order to gen...

Eine der Aufgaben eines ME-Systems (Manufacturing Execution Systems) stellt die Feinplanung und –steuerung der Produktion dar. ME-Systeme werden in der IT-Infrastruktur eines Unternehmens zwischen dem ERP-System und dem Shop-Floor angesiedelt und bilden hier einen geschlossenen Regelkreis. Die Feinplanungsaufgabe besteht darin, den Produktionsplan permanent an die Veränderungen aus dem ERP-Syst...

A typical way to build surface numerical models or Digital Elevation Models (DEMs) for Geographical Information Systems (GIS) is by processing the stereo images obtained from, for example, aerial photography or SPOT satellite data. These GIS can perform many computations involving their geographic databases. The quality control of a geographic database, and in particular the topological and geo...
