Geospatial data are usually featured with three-dimensions in space and fast evolvement with time. The delivery of a large volume of geospatial data requires a well built network environment. This fact also challenges the online visualization. In order to accelerate data transmission and rendering, progressive methods have been applied in this paper. A k-d tree structure is incorporated to construct...
The increasing utilization of geospatial information to facilitate emergency decisions requires a Geographic Information System (GIS) to process large amounts of geospatial data in a timely fashion. Real-time GIS applications require sub-second response time to analytical operations on large and highly dynamic datasets for timely decisions. Leveraging idle workstations is a feasible method to meet...
