This study develops a geographical information system (GIS) approach for automated processing of the Next Generation Weather Radar (NEXRAD) Stage III precipitation data. The automated processing system, implemented by using commercial GIS and a number of Perl scripts and C/C++ programs, allows for rapid data display, requires less storage capacity, and provides the analytical and data visualiza...

Since 1996 Pierce County has utilized an ArcView application, called CountyView, as the county's enterprise GIS. After six years of use the application continues to draw more and more users, most of them grateful to be able to access the system from their desktop. This paper will attempt to describe what has made CountyView a successful enterprise GIS and categorize the elements needed in creat...

A framework is presented which may be used to analyze and evaluate intermodal networks. An intermodal network can be defined as an integrated transportation system consisting of two or more modes. Modes on intermodal networks are connected through facilities which allow travelers and/or freight to transfer from one mode to another during a trip from an origin to a destination. The model may be ...

Mapping of diseases has, since John Snow produced his famous cholera maps of London in 1854, been recognised as an essential tool in public health. A Geographical Information System (GIS) is more than mapping diseases: it manages, analyses and presents data that are linked to geographical locations. GIS enables creation of maps and can present data on national and regional level, but also on ve...

BACKGROUND Geographic information systems (GIS) are increasingly recognized tools in maternal health. OBJECTIVES To evaluate the use of GIS in maternal health and to identify knowledge gaps and opportunities. SEARCH STRATEGY Keywords broadly related to maternal health and GIS were used to search for academic articles and gray literature. SELECTION CRITERIA Reviewed articles focused on mat...

The field of GIS (S for Systems, Sciences, Services, and Studies) is at a cross-road in the early 2010s. Aiming to link the multiple visions for the next phase of GIS development, this article suggests that the emerging open GIS should serve as a guiding concept. Contextualized in the broader literature of open science, this article proposes open GIS should include eight dimensions related to d...
