With the fast development of cities in China, more and more geographic information systems (GIS) that have been combined with remote sensing information are applied to help decision-maker or company to manage and make macroscopic decisions. But the accuracy of integrated GIS was ignored by both user and producer. It followed that the uncertainty of GIS may result in wrong decision. For these re...

The study aims at developing a GIS based contamination Risk Assessment procedure in water distribution systems. Water distribution network analysis model EPANET 2.0 was integrated with ArcGIS 8.3 for the water quality analysis retrieving data from the GIS database. Water supply system of Zone VIII of Guntur, India was selected for the case study. The results of water quality simulation were dis...

Like in most other countries, influenza surveillance in The Netherlands is based upon influenza-like illness (ILI) consultations reported by sentinel general practitioners (GP). In addition, an internet-based monitoring of ILI in the general population started in 2003/2004 (Great Influenza Survey (GIS)). We compared GIS results over 5 influenza seasons with results from the GP system. Weekly IL...

BACKGROUND Data analysis in community health assessment (CHA) involves the collection, integration, and analysis of large numerical and spatial data sets in order to identify health priorities. Geographic Information Systems (GIS) enable for management and analysis using spatial data, but have limitations in performing analysis of numerical data because of its traditional database architecture....

This paper describes the 3D GIS research efforts done by the GIS research groups as well as by major GIS software vendors world wide, namely Environmental System Research Institute (ESRI) Inc., ERDAS Inc., Integraph Inc., and PCI Geomatics Inc. Research works done by the authors of this paper formed major discussion of this paper including a discussion on why the 3D GIS software is difficult to...

The functionality of spatial process analysis is the foundation of GIS’s comprehensive application . To realize such a goal. it is desirable that not only the data model of GIS can represent the datasets needed by spatial process models, but also GIS is able to do multitemporal spatial analysis. But most of current GISs are static in essence, they cannot represent temporal information and tempo...

An organization’s strategies for managing Geographic Information Systems (GIS) play a crucial role in the success of the technology within the organization. As with any technological innovation, the key factor in GIS success is how it is applied to solve the organization’s business problems. Corporatewide strategies to introduce, implement, and operate the GIS determine how well it serves busin...

Gross chromosomal rearrangements (GCRs) play an important role in human diseases, including cancer. The identity of all Genome Instability Suppressing (GIS) genes is not currently known. Here multiple Saccharomyces cerevisiae GCR assays and query mutations were crossed into arrays of mutants to identify progeny with increased GCR rates. One hundred eighty two GIS genes were identified that supp...
