Virtual reality geological studio (VRGS)
Digital outcrop models are three-dimensional models of geological exposures created using technologies such as laser scanning and digital photogrammetry. These 3D models allow accurate representations of the geological exposure to be taken back into the office for further interpretation and analysis, thus making more efficient use of time in the field. VRGS provides the geological toolkit to process, analyse and interpret these data.
Digital outcrop data have applications in petroleum, mining and engineering geology, and indeed in any field where statistical information from geological exposures may be of use.
Virtual Reality Geological Studio (VRGS) is a 3D data visualisation and interpretation software tool, developed by Dr. David Hodgetts of the University of Manchester, for geoscientists working with 3D digital outcrop models (DOM).
Focusing mainly on point cloud and triangulated mesh data, multiple attributes can be calculated based on surface geometry and used to assist interpretation. Input data can be from LiDAR, Structure from Motion (SFM), DEM or any other point cloud type dataset. A wide variety of input data types are supported (including common formats such as PLY and OBJ), and further types can be added on request.
Interpretation tools include structural measurement (dip/azimuth) of faults and beds, polylines and geobodies, with associated analysis of these data types with stereonets and statistical output. Interpretation data can be exported to ascii text files if necessary.
