GeoAnalysis Tools - ArcScene Extension for the Analysis of 3D Geological Outcrop Models

GeoAnalysis Tools is an ESRI ArcScene extension developed by Geological & Historical Virtual Models, LLC, based upon research performed in collaboration with the University of Texas at Dallas. GeoAnalysis Tools allows for the interactive analysis of orientation and deformation features of a 3D model of a geological outcrop. The model can be either a photorealistic solid model constructed by draping photographs on a triangulated irregular network (TIN) derived from a LIDAR point cloud or it can be the point cloud itself. Basic field measurements such as strike-dip, trend-plunge, and bedding thickness can be made on the 3D model. The program provides for the extrusion of features in a trend-plunge direction to facilitate the nature of the deformation. Down-plunge cross sections are rapidly created from traces of features such as bedding contacts and displayed in ArcMap.
