Mobile Geographical Information System (Mobile GIS) is a Geographical Information System based on mobile computing and mobile Internet. It is not a conventional GIS modified to operate on a smaller computer, but an extension of Web GIS to mobile Internet including wireless Internet/Intranet and mobile communication network. But architectures of Web GIS are unsuitable for Mobile GIS, because of ...

This perspectives paper uses the seminal article of Goodchild (1992) as a lens through which to review and reflect upon several longstanding issues that have influenced the field of geographic information science in the past and will continue to be important at least into the next decade. Under the category of theory, the continuing issue of ‘tool versus science’ now has implications for the de...

This paper introduces a process for developing Web GIS (Geographic Information Systems) applications. This process integrates the NDT (Navigational Development Techniques) approach with some of the Organizational Semiotic models. The use of the proposed development process is illustrated for a real application: the construction of the WebMaps system. WebMaps is a Web GIS system whose main goal ...

* Corresponding author Automated generation of maps from remotely sensed images remains an unsolved problem in the quest for bringing together image analysis and GIS technologies. This paper proposes a framework for an automatic scene interpretation system with the objective of populating/updating a GIS database. The proposed approach exploits semantic contextual information, combining scene an...

Problem statement: GIS has several techniques and functions that can be used for health services planning. Each one of these functions can be applied for different health related issues. Approach: The first part of this study reviews the relevant GIS functions that are used by health care planning researches and identifies the advantages of using these functions. The second part of the study fo...

The term "Grid" has become common parlance among parallel and distributed computer scientists to denote a middleware infrastructure for wide-area scientific and engineering computing. Information services are a vital part of any Grid software infrastructure, providing fundamental mechanisms for discovery and monitoring and thus for planning and adapting application behavior. Grid Information Se...

In this article, we describe two software design patterns that can be reused in the design of object-oriented geographical information systems (GIS). The first of them, called Spatial Object, captures the common structure and dynamics of the spatial entities represented in a GIS. The second one, called Spatial Graph, provides a solution to REVISTA COLOMBIANA DE COMPUTACIÓN Volumen 1, número 1 P...
