With the progress of mobile GIS technology there is a great potential for adopting wireless communications and Internet mapping services for regional environmental management programs and natural habitat conservation. This paper provides an overview of a NASA-funded research project that focuses on the development of mobile GIS tools and wireless Internet Map Server (IMS) services to facilitate...

A number of approaches for integrating GIS and qualitative research have emerged in recent years. Despite significant growth in public participation GIS (PPGIS) literature since the 1990s, little engagement by e-government scholars is evident in the extensive scholarly PPGIS debates. To fill this void, recent trends in PPGIS adoption by local governments are analyzed. Three waves of GIS are ide...

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...

A geographic information system (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information. With the advancement of technologies and internet it allows for the emerging of GIS to be considered as a WebGIS. In order to build a WebGIS for connecting to geodata sources we need commonly acceptable standards for...

The contribution deals with issues that are very closely connected: Web services model, Dynamic GIS and the problem of uncertainty of spatial data and discusses the possibilities of the context use as a reflection of the system of understanding. The problem of the relation to the decision support system is addressed and GIS as a tool dealing with all phases of knowledge structure. GIS Web servi...

Computer-Aided Design (CAD) and Geographical Information System (GIS) are being used in tandem to support a variety of decisions throughout the life cycle of civil infrastructure systems. Existing CAD and GIS platforms have been developed independently with different purposes resulting in significant differences in terms of data formats they support, terminology they utilize, semantics of conce...

This article presents the conceptual design of a collaborative web-based Geographic Information System (GIS) for land use planning in which all parties including land use planners, applicants/developers, and community stakeholders can participate. The approach employs three-tier architecture built in a Java client-server environment, and consists of the ESRI ArcGIS 9.2® Server Advanced Edition ...

Attesting to the powerful capabilities and in technology trends, many scholars envisioned the consolidation of geographic information systems (GIS) into vital tools for disseminating spatial information. GIS are presently used to inform, advise and instruct users in several contexts and to further engage citizens in decision-making processes that can impact and sustain policy development. Inter...

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 ...
