ABSTRACT This paper describes the Active Response GIS (AR/GIS) for resource planning and land­ allocation deliberation. AR/GIS is an integrated system which combines GIS and electronic meeting software. This combination provides the voting, information organization, and brainstorming of an electronic meeting system, and supports interaction with geographic data sets. The AR/GIS system can impro...

This paper discussed the concepts and development of a multimedia geographic information system (GIS) for analyzing and visualizing both spatial and temporal geographic information in image/vector format as well as multimedia information in descriptive text, graphics, ground photographs and digital video clips. The multimedia GIS presents a new way to analyze and visualize geographic informatio...

We describe a uniied framework for representing and manipulating binary topological relationships between complex regions, which are arbitrary compositions of homogeneous 2-dimensional surfaces, possibly with holes. Previously, compositions of regions and regions with holes were treated separately and in a restrictive scenario, where it is required that the composing regions should be disconnec...

this paper addresses a multi-criteria decision based methodology to develop a road network cost function for route finding analysis in a geographic information system (gis). over the years, several studies relating to route planning process in gis and intelligent transportation systems (its) have been conducted, most of which rely on the use of one-dimensional variables like distance or time as...

Patterns have been used in software engineering to enable the reuse of successful solutions for recurrent problems in various steps of the software development process. In the development of geographic information systems (GIS), usually only geographic data are reused. This paper shows the adequacy of deriving as well as applying analysis patterns in the conceptual data modeling process of geog...

In an effort to contribute to the conceptualization of the burgeoning field of Volunteered Geographic Information (VGI), we propose to review selected definitions and debates around Geographic Information Systems (GIS). “Traditional” geographic information emerges from the interplay of the components of GIS: hardware, software, data, and application, and it is shaped by the processing of geogra...

Geographic information systems (GIS) are becoming more usual due to the improved performance of computer systems. The traditional three-tier architecture for information systems is being used for the software architecture of GIS, but geographic information has some special qualities that make the use of the traditional architecture inappropriate. We analyze in this paper the special characteris...
