Due to the driving forces of the Internet and network communication technology, the paradigm of Geographic Information Systems (GIS) is shifting [16, 19]. Moreover, with the advances in computer technology and GIS science, distributed GIS become practical and widely acceptable. Traditional GIS plays an extremely valuable role in GIS applications by providing a wide variety of tools to handle ge...

This paper presents research in Geographic Information Systems interoperability. Also, paper describes our work in development, introduces interoperability framework called GeoNis, which uses proposed technologies to perform integration task between GIS applications and legacy data sources over the Internet. Our approach provides integration of distributed GIS data sources and legacy informatio...

LINK TO PAPER The Challenges of Implementing Enterprise GIS at the City of Fort Worth Track: State and Local Government Author(s): Len MacKenzie During the past year, the City of Fort Worth, Texas has been implementing an enterprise GIS based on ESRI's suite of software products. This paper will give an overview of the technical and administrative challenges involved in coordinating enterprise ...

The current applications of geographic information systems (GIS) applications to non-point-source pollution modeling for agricultural area are reviewed with respect to the requirements for GIS, the hydrological/water quality modeling processes, and integration between GIS and Non-Point-Source Pollution (NPSP) models. Some necessary considerations for future studies are also discussed by summari...

Modern geographical information systems make it possible to integrate information from multiple sources in different forms for querying and analysing information. So the importance of geospatial databases is growing from day to day, and their applications extend beyond the traditional applications of geospatial databases and GIS. One of the most recent challenges is integrating geospatial data ...

Geographical Information Systems (GIS) are increasingly used to appreciate how past people experienced their world. Two key approaches, visibility and cost surface studies, have been the dominant form of analysis to help archaeologists to reconstruct and visualize space, in other words to help archaeologists understand what it was like to be ‘there’ in the past. This paper seeks to question the...
