Introduction Previous research provides only partial evidence about the trends in interorganizational development and sharing of geographic information systems (GIS) and databases, the obstacles and facilitators of interorganizational activities, and the benefits derived from the joint activities. Anecdotal evidence is provided primarily through conference presentations, usually as a discussion...

The purpose of this paper is to discuss research directions in GIS. In doing so I will deliberately broaden the meaning of "GIS" to include a wide range of activities within the broad rubric of digital geographic information, since it seems to me that "GIS" is now generally used in that broad sense, rather than in the narrower sense of a software system designed specifically to store, retrieve,...

An increasing number of institutions are challenged with implementing robust geographic information system (GIS) capabilities for a large number of individuals through informationsharing and interconnected networks. In the past, numerous technological roadblocks hampered the successful implementation of enterprise GIS (EGIS). With the advent of high-speed networks; increasingly fast computers; ...

The geographic context is essential both for environmental research, and for policyoriented environmental management. Geographic information systems are as a result increasingly important computing applications in this domain, and an understanding of the underlying principles of geographic information science is increasingly essential to sound scientific practice. The review begins by defining ...

Geographical Information Systems (GIS) are powerful tools in the field of invasive species management. GIS can be used to create potential distribution maps for all manner of taxa, including plants, animals, and diseases. GIS also performs well in the early detection and rapid assessment of invasive species. Here, we used GIS applications to investigate species richness and invasion patterns in...

The increasing popularity of the Internet has led to the development of Web applications, known as Web GIS. A geographic information system (called GIS from now) is a software system that manages geo-referenced information. GIS systems are an automated system used for storing, analysing and manipulating geographical information. Geographical information represents objects and actions where geog...
