Despite the growth of visualization, rendering, and interaction techniques in the visualization community, researchers are often left with few efficient options for using other common types of data in visualization systems. In this work we illustrate a new data structure for spatial-temporal data that is designed for the needs of the information visualization and visual analytics communities. We ... read morealso discuss why using existing work in graphics and scientific visualization, rather than using the work in the geographic information systems community, is a better choice for building spatial structures for information visualization and visual analytics software. In addition to proposing a standard storage system for visualization researchers to use for geospatial data, because of our structure's runtime performance, our contributions also allow researchers to use larger data sets in interactive visualization systems.read less
