Introduction According to the National Research Council (2010), a significant challenge in the GISciences is the creation and development of tools that enable the results of scientific modeling to be easily understood. For science-informed decision making as well as for the purposes of informing and engaging ordinary citizens in discussions regarding geographical technologies, the National Rese...

Geographic information systems provide a high level of functionality for spatial analyses but are not yet able to provide extended functionality needed to create a truly "scientific GIS". Functionality that is lacking include time series analyses, calculation of the volume of the overlap between two volumes or calculation of the intersection of a vector path with a volume. Other functions inclu...

Using ArcGIS Topology Rules for Improving Data Maintenance for Navy PWCs Track: Defense and Intelligence Author(s): Dale Dunham The Public Works Centers in Navy Regions Japan and Hawaii had converted their GIS data maintenance process to the SDE Geodatabase environment realizing significant efficiencies. With the release of Topology rule-based editing in ArcGIS 8.3, significant process improvem...

Many decision tasks in disaster management are concerned with spatial patterns and spatial decision problems often require that a large number of feasible alternatives be evaluated based on multiple criteria. Although Geographical Information Systems (GIS) provide extensive spatial analysis and data visualization power to users, such systems offer a limited capacity for tackling complex spatial...
