The document discusses the process used by Planet 9 Studios to create 3D models of ports and harbors for the US Navy. It involves collecting on-site photos and geospatial data, importing the data and terrain into Global Mapper, setting the projection, importing imagery, exporting to 3ds Max for texturing and modeling, then exporting to X3D format for use in simulations and training. The goal is to accurately represent facilities in a geo-registered 3D format.
