We map and survey caves to understand the resource. Cavewhere can help you understand that resource, by modeled, drawn, and mapping in 3D. Cavewhere is yet another way to visualize caves, and it takes this slightly different 3D approach, differing from other software such as Therion, WinKarst, Walls, and Tunnels. Cavewhere is a free, open-source, cross-platform, and hopefully caver friendly 3D GIS program.
