USING DIGITAL TOOLS FOR THE ANALYSES OF 3D VIRTUAL MODELS IN THE CLASSROOM SUCH AS THE RAMSEY FOLD CLASSIFICATION

Graduate students are collaborating with undergraduates in designing interactive analyses tools operating on 3D photorealistic models to virtually mimic field exercises in the classroom for undergraduate courses they have taken. These tools would carry out various geometric analyses using software built around ESRI Arc GIS-Arc Scene and Arc Map as the platform, mainly UTD DISP (Digital Integrated Stratigraphic Project) Tools and the commercial GHVM GeoAnalysisTools (GAT). GIS type software can be intimidating so GUIs are used to provide more accessible versions of the tools. Using such 3D models and tools the geology of the outcrop can be viewed from any angle, and accurate geometric measurements made with the digital tools, such as required for the Ramsey fold classification. Virtual models are not intended to replace field geology but to allow a simulated interaction with an outcrop not readily accessible or if accessible perhaps before and/or after visiting the site. Since the exercises are digital all results can be archived for review by students and instructors. We will demonstrate this concept and the advantages of using high resolution 3D photorealistic models which are geo-referenced to teach geology. We have been building a series of virtual models to be available for instruction and training ultimately accessible through the INTERNET.
