Three-dimensional Mobile Mapping of Caves
Existing methods of cave survey are time consuming and require significantly more time than naturally moving through the cave. The efficiency of these methods, even in the case of state-of-the-art laser-scanning technology, is fundamentally limited by the requirement that measurements be taken at static locations. We present a mobile approach to cave mapping, in which a lightweight 3D laser sca...
متن کاملIntegrating geomorphological mapping , trenching , InSAR and GPR for the 1
13 This contribution illustrates the advantages of integrating conventional 14 geomorphological methods with InSAR, ground penetrating radar and trenching for 15 sinkhole mapping and characterization in a mantled evaporite karst area, where a 16 significant proportion of the karstic depressions have been obliterated by artificial fills. 17 The main practical aim of the investigation was to eluc...
متن کاملSurveying and Mapping Caves by Using 3D Digital Technologies
In this paper, we propose an original three-dimensional (3D) computer-aided approach for surveying and mapping caves to get line drawings. By introducing 3D digital technologies into the line drawing, our approach has advantages in improving the drawing accuracy while cutting a lot of time costs. The 3D digital technologies are used to reconstruct accurate 3D models of real scenes. Then, the li...
متن کاملGeomorphological mapping and geophysical profiling for the evaluation of natural hazards in an alpine catchment
Liechtenstein has faced an increasing number of natural hazards over recent decades: debris flows, slides, snow avalanches and floods repeatedly endanger the local infrastructure. Geomorphological field mapping and geoelectrical profiling was used to assess hazards near Malbun, a village potentially endangered by landslides, and especially debris flows. The area is located on the tectonic conta...
متن کاملGeomorphological Mapping with Respect to Amplitude, Coherenceand Phase Information of Ers Sar Tandem Pair
Radar interferometry is a technique which makes use of interfered signal of two radar echoes for topographic elevation and terrain element mapping. ERS Synthetic Aperture Radar (SAR) tandem pair with minimum possible temporal baseline of 1-day and with precise orbit control to obtain suitable interferometric spatial baseline is appropriate for interferometric study in terrain analysis. In this ...
