3D GIS is becoming increasingly important, especially for practices such as the analysis of Geophysical data (such as GPR, gravimetric studies and even borehole data). Virtual Reality provides an exciting space to perform this analysis by allowing the practitioner to "enter into the data" and walk around it. ViRGiS is a FOSS project to develop this idea. ViRGiS (www.virgis.org) is a FOSS project to create a GIS in Virtual Reality. This allows the GIS practitioner to actively engage with 3D GIS data in native formats in a realistic 3D space. 3D GIS is becoming increasingly important, especially for practices such as the analysis of Geophysical data (such as GPR, gravimetric studies and even borehole data). Virtual Reality provides an exciting space to perform this analysis by allowing the practitioner to "enter into the data" and walk around it. They can actively interact with the data and change and mould the data in a naturalistic and simple manner. This talk will describe the solution and will use a Geophysics Case Study and a Point Cloud Mapping case study to show the abilities of the platform.
