Laser scanning is a very efficient way to generate realistic high resolution digital models of 3D geological outcrops. This paper discusses the methodologies involved in the creation and analysis of virtual outcrops based on laser scanner data. The visualisation of the laser scanner data as a photorealistic 3D object is described. Geological features picked(More)
A new 2-D traveltime tomography algorithm has been developed for use with long offset seismic streamer data. The forward problem is solved using initial value ray tracing in Delaunay triangulated grids. The traveltimes are calculated analytically. The linearised joint interface and velocity inversion is regularised via a geostatistical smoothing(More)
