Voyager: An Interactive Software for Visualizing Large, Geospatial Data Sets

摘要

This paper describes the development and main operational capabilities of Voyager, a PC-based, geospatially-enabled piece of software that can fuse and visualize large, multi-variable data sets that change in space (XYZ) and time (T). The new software has the ability to simultaneously visualize imagery, bathymetry/terrain, true volumetric (voxel), and flow field data in a fully interactive geo-referenced mode. In addition to providing global coverage, a key feature of this software is the capability to interactively visualize large data sets while operating on a desktop PC. This is achieved by using tiling and level-of-detail (LOD) technology for terrain, imagery, and volumetric data, as well as compression techniques and the multi-threading capabilities of modern PCs.
