3D Geological Modeling and Visualization of Rock Masses Based on Google Earth: A Case Study

摘要

Google Earth (GE) has become a powerful tool for geological modeling andvisualization. An interesting and useful feature of GE, Google Street View, canallow the GE users to view geological structure such as layers of rock massesat a field site. In this paper, we introduce a practical solution for building3D geological models for rock masses based on the data acquired by use with GE.A real study case at Haut-Barr, France is presented to demonstrate oursolution. We first locate the position of Haut-Barr in GE, and then determinethe shape and scale of the rock masses in the study area, and thirdly acquirethe layout of layers of rock masses in the Google Street View, and finallycreate the approximate 3D geological models by extruding and intersecting. Thegenerated 3D geological models can simply reflect the basic structure of therock masses at Haut-Barr, and can be used for visualizing the rock bodiesinteractively.
