Public Participatory Geographical Information Systems (PP GIS) is a field of research that focuses on the use of GIS by the general public and aims at involving citizens in a decision-making processes. PP GIS applications increasingly use the Internet as a platform for communication and dissemination of information. They link community participation and geographic information in a diversity of ...

The notion of “real world” geographic information systems (GIS) technology can be examined through reviewing how one of Brazil’s largest non-governmental organizations (NGOs), Fundação SOS Mata Atlântica, has evolved in an iterative process with the development and use of GIS technology. Examining the actual ways in which GIS is incorporated into the activities and actions of NGOs, such as Fund...

The principles and technologies of computer supported cooperative work (CSCW) are increasingly integrated in many areas to support distributed collaborative production, especially with the rapid growth of the Internet and broadband network technologies. To achieve the improved efficiency and productivity, group processes and interaction must be properly addressed and the design of supporting co...

The purpose of this paper is to provide an introduction to geographic information systems (GIS) and a research framework for information systems researchers. The paper summarizes the main GIS features, functions, and capabilities, including a research framework for GIS. In addition, several opportunities for research are suggested including those related to GIS management, organizational impact...

Figure 20: Sample (a) region, (b) its binary array, (c) its maximal blocks, and (d) the corresponding quadtree (after SAMET 1990a). IX he first textbook on GIS was published in 1986. Today, we can find dozens of books dealing with GIS. Yet, it is dif...

The diversity of spatial information systems promotes the need to integrate heterogeneous spatial or geographic information systems (GIS) in a cooperative environment. This paper describes the research project ISIS (Interoperable Spatial Information System) which is a semantic mediation approach to support GIS interoperability. Its key characteristic is a dynamic resolution of semantic conflict...

This study describes the origins, boundaries, and structures of collaborative geographic information systems (CGIS). A working definition is proposed, together with a discussion about the subtle collaborative vs. cooperative distinction, and culminating in a philosophical description of the research area. The literatures on planning and policy analysis, decision support IDEA GROUP PUBLISHING Th...
