Effect of lossy data compression techniques on geometry and information content of satellite imagery
Data compression Satellite imagery JPEG Wavelets
2016/5/23
The recording and transfer rates of digital imaging systems can not keep abreast of the actual captured amount of data.Because the compression rates of standard loss-less techniques are still too low,...
EXPERIMENTS WITH UAS IMAGERY FOR AUTOMATIC MODELING OF POWER LINE 3D GEOMETRY
UAS Dense Matching Transmission Lines Modeling
2015/9/10
The ideal mapping technology for transmission line inspection is the airborne LiDAR executed from helicopter platforms. It allows for full 3D geometry extraction in highly automated manner. Large scal...
DETECTION AND RECOGNITION OF CHANGES IN BUILDING GEOMETRY DERIVED FROM MULTITEMPORAL LASERSCANNING DATA
Change detection Urban Laser scanning DEM/DTM Segmentation Comparison Classification Recognition
2015/6/1
The work presented is part of a project that aims at change detection in urban areas after strong earthquakes. Detection and classification of these changes are used to recognise building damages as a...

Synthetic aperture radar technology has revolutionized earth observation with very high resolutions of below 5m, making it possible to distinguish individual urban features like buildings and even car...
Exploiting Satellite Focal Plane Geometry for Automatic Extraction of Traffic Flow from Single Optical Satellite Imagery
Optical Satellite Data Focal plane assembly Traffic detection Moving objects detection
2014/12/4
The focal plane assembly of most pushbroom scanner satellites is built up in a way that different multispectral or multispectral and panchromatic bands are not all acquired exactly at the same time. T...
AN IMPROVEMENT ON GEOMETRY-BASED METHODS FOR GENERATION OF NETWORK PATHS FROM POINTS
Network path Geometry-based VGI
2014/12/1
Determining network path is important for different purposes such as determination of road traffic, the average speed of vehicles, and other network analysis. One of the required input data is informa...
