Spatial outbreak detection analysis tool : a system to create sets of semi-synthetic geo-spatial clusters
… Because of this shortage, creating suitable geotemporal test clusters for surveillance algorithm validation is essential. Described is an automated tool that creates artificial patient clusters by varying a large variety of realistic outbreak parameters. The cluster creation tool is an …

Cluster detection and analysis with geo-spatial datasets using a hybrid statistical and neural networks hierarchical approach
Spatial datasets contain information relating to the locations of incidents of phenomena for example, crime and disease. Areas that contain a higher than expected incidence of the phenomena, given background population and census datasets, are of particular interest. By analysing the locations of …

Hydrogeo-Eco-Systems in Aquaba/Jordan - Coasts and Region
… region (Jordan) were investigated on their hydrogeo-ecosystem. The results of the research were translated into digits to build a geo-spatial data base. The fillings of the graben aquifer receive indirect type of recharge through the side wadis which drain the highlands. Surface water balance was …

Participatory GIS for growth management in the Cheat Lake planning district of Monongalia County, West Virginia
Participatory Geographic Information Systems (PGIS) can be an effective methodology for collecting public input in local land use planning and smart growth management. PGIS-based approaches provide residents with an opportunity to discuss and map their priority land use issues and to identify land …

The Impact of Climate Variability and Conflict on Childhood Diarrhea and Malnutrition in West Africa
… population ranking. The first two studies use geo-spatial techniques to 1) determine if there are areas of elevated risk after controlling for climatic and other covariates and 2) determine whether there is spatial variation in the associations between diarrheal disease and climatic and other …

Development of a Multicriteria Spatial Decision Support System with Application to the Economic Optimization of Aircraft Based Weather Data Collection
… the TAMDAR system requires a multicriteria spatial decision support system (MC-SDSS) that facilitates the efficient selection of the most desirable data points to collect based on a limited budget. To optimize the data collection each data point must be assigned a value by the TAMDAR DSS and …
