A SOFTWARE SYSTEM FOR EFFICIENT DEM SEGMENTATION AND DTM ESTIMATION IN COMPLEX URBAN AREAS
segmentation urban semi-automatio three-dimensional
2015/6/1
Designing an automatic DEM segmentation method that is successful under
all circumstances can hardly be envisaged. To facilitate the segmentation process, a user-friendly, interactive software enviro...
EXTRACTION OF FEATURES FROM OBJECTS IN URBAN AREAS USING SPACETIME ANALYSIS OF RECORDED LASER PULSES
Urban Analysis Simulation Laser scanning LIDAR Measurement Feature
2015/6/1
In this paper we describe a simulation system and investigations for analysis of recorded laser pulses. A simulation setup that considers simulated signals of synthetic objects was developed for explo...
MONITORING URBAN AREAS FOR ENVIRONMENT AND SECURITY THROUGH REMOTE SENSING
Urban remote sensing GMES
2015/5/29
This paper aims at providing an introduction to the topic of urban area management through remote sensing. It builds over the experience of the GUS (GMES Urban Service) project, funded by ESA in the f...

3D Buildings Visualisation Photogrammetry VRM
2015/5/19
Developing realistic 3D models of cities provides designers, planners, the public, and the others with imagery closely coupled with the human expertise. This paper continues on the results of an earli...
SHADOW DETECTION IMPROVEMENT USING SPECTRAL INDICES AND MORPHOLOGICAL OPERATORS IN URBAN AREAS IN HIGH RESOLUTION IMAGES
Shadow detection high resolution
2015/5/6
While high-resolution remote sensing images have increased application possibilities for urban studies, the large number of shadow areas has created challenges to processing and extracting informati...
HIGH RESOLUTION AIRBORNE SAR IMAGE CHANGE DETECTION IN URBAN AREAS WITH SLIGHTLY DIFFERENT ACQUISITION GEOMETRIES
Change Detection SAR Remote Sensing Imaging Geometry Feature Building
2015/4/1
Before applying change detection, high resolution SAR (Synthetic Aperture Radar) imagery benefits from advanced denoising mechanisms to preserve details and minimize speckle. We propose a change detec...
