GIS-based Multicriteria Decision Analysis (GIS-MCDA) provides a rich collection of techniques and procedures for landslide susceptibility mapping. In this study landslide susceptibility was evaluated by applying different analytical GIS techniques based on Ordered Weighted Averaging (OWA) criteria. The OWA-MCDA is complemented by a Monte Carlo Simulation (MCS) and a Dempster-Shafer Theory (DST)...

Geographic information systems (GIS) education is at a crossroads in the United States. Since its inception in the early 1990s, GIS has diffused slowly into select groups of K-12 classrooms through the efforts of geography and environmental educators. However, many of the assumptions underpinning the initial period of enthusiasm for the technology are now being questioned. This paper reviews is...

“When public spaces are successful [...] they will increase opportunities to participate in communal activit y”,(Carr, Francis, Rivlin, & Stone, 1993). The city of Cairo has an enormous number of liveable streets that welcomes cultural events; however, many of such streets lack the design principles that sustain and enhance the occurrence of those events. Trials to investigate and upgrade the u...

The paradigm of geographic information systems (GISs) is shifting from a closed, centralized GIS architecture, to an open, distributed geographic information services (GIServices) framework. With advances in computer networking and wireless communication technology, GIS is moving toward an integration of GIServices and spatial analysis functions via the internet and wireless communication. Wire...

P lanning's " quiet revolution " in information technology (Godschalk and McMahon, 1992) may have finally come of age. Through the decade of the 1990s, Geographic Information Systems (GIS) has evolved from a technological novelty distinguished by its operational complexities into a much easier to use, less expensive, and now seemingly indispensible tool of the planning profession. GIS skills th...

This paper provides a new representation for fields (continuous surfaces) in Geographical Information Systems (GIS), based on the notion of spatial functions and their combinations. Following Tomlin’s (1990) Map Algebra, the term “Map Calculus” is used for this new representation. In Map Calculus, GIS layers are stored as functions, and new layers can be created by combinations of other functio...
