There is an increasing interest in agent-oriented technology, spanning applications as diverse as information retrieval, user interface design and network management. Application of intelligent agents in the GIS environment is actively being explored. Many different types of agents are being employed to improve usability of GIS software as well as users access to geospatial data and services av...

geographic information systems (gis) are one of the fastest growing computer-based technologies of past two decades, yet, full potential of this technology in construction has not been realized. based upon gis capabilities, construction site layout is one of the areas that gis could be applied. the layout of temporary facilities (tfs) such as warehouses, fabrication shops, maintenance shops, co...

This article presents a logic-based formalism for formal reasoning about visual representations. This formalism is based on previous work about describing visual notations [Haarslev, 1998a]. However, in this article we discuss major extensions to this formalism providing decidable reasoning mechanisms that support truly spatial domains such as geographical information systems (GIS). We demonstr...

The complex and proprietary nature of geospatial data makes them almost non-sharable among large user community. GIS interoperability is necessary for realizing a successful spatial data infrastructure. With the advancements of web service technology, GIS interoperability has made a paradigm shift – from monolithic GIS providers to distributed geospatial services. The applicability of web servi...

Selecting a Geographic Information System (GIS) based on Free Software (FS) is a difficult task vis-à-vis its technological complexity, the wide range of this type of systems and their functionalities. Therefore, provides a set of quality characteristics used to evaluate FS-GIS. This set of characteristics is presented on the product perspective of the Systemic Software Quality Model (MOSCA), w...

But it has its flaws. As early as the 1980's, the GIS community has been accused of elitism, archaism and being, in essence, “ivory tower geomancers.” Although not all of the GIS community deserved these pejoratives, the problem may have arisen because of the things we “fought” about, such as the use of mainline IT databases, the separation of geometry and “nongraphic” attributes, the effective...

DEFINITION: A geographic information system (GIS) is a computer application designed to perform a wide range of operations on geographic information. Geographic information is defined as information about locations on or near the surface of the Earth, and may be organized in a variety of ways. Thus a GIS includes functions to input, store, visualize, export, and analyze such information. Commer...

This paper introduces an analysis pattern for Mobile Geographic Information Systems (Mobile GIS) focused on urban administration applications. This pattern provides a class and associations diagram and can be used in the development of an urban Mobile GIS application. The paper also describes a process that guided us in obtaining this analysis pattern, presenting an example of its use in the co...
