The Open Geospatial Consortium (OGC) defines a number of standards (both for data models and for online services) that have been widely adopted in the Geographical Information System (GIS) community. In this paper we will describe our group's efforts to implement GIS services according to OGC standard specifications in accordance with the Web Services approach. This paper focuses on the Web Map...

In Ghana, there is general indiscipline and lack of transparency in the land market. This is characterized by multiple sales of residential parcels, land encroachments and haphazard development. Land records form the bases of all land reforms and therefore regular online update of land records is essential.The objective of the web-based land records system therefore was to provide a quick, secu...

A growing number of urban GIS-based applications for the web have been developed and marketed last decade (traffic monitoring, site location and remote geographic databases access, ....). The development of these applications is mostly a heavy task and time consuming. To address problems related to the development and the customisation of these applications, the CASE Tool named AIGLE [3] is ext...

The novelty of our approach resides in the processing of real-time power fault events from DDS to GIS web clients in three stages, as illustrated in Figure 2: 1) When the fault overlay is selected, a DDS subscriber is internally launched and connected to the GIS client in order to capture fault events, ie voltage sags, swells and other power disturbances detected at the smart meters and substat...

Lake Débo and Walado Débo, one of the major Sahelian wetlands is located in Inner Delta (Mali). Given the environmental and community interest in this wetland, there is urgent need to share spatial data on natural resources. Most of the covered information is published in (internal) reports with a limited distribution. With the advent of GIS and Internet technologies, the conventional intricaci...

Web Geographic Information System (Web GIS) has been extensively and successfully exploited in various arenas. However, to date, the application of this technology in public health surveillance has yet to be systematically explored in the Web 2.0 era. We reviewed existing Web GIS-based Public Health Surveillance Systems (WGPHSSs) and assessed them based on 20 indicators adapted from previous st...

In this paper we present the Web based framework that provides efficient management, tracking and displaying of data about mobile objects in Web based Geographic Information Systems (Web GIS) and Location Based Services (LBS) applications built on top of it. The proposed framework heavily exploits contemporary Web data exchange and display technologies such as XML, GML and SVG integrating geosp...

The progressive consolidation of information technologies on a large scale has been facilitating and progressively increasing the production, collection, and diffusion of geographic data, as well as facilitating the integration of a large amount of external information into geographic information systems (GIS). Traditional GIS is transforming into a consolidated information infrastructure. This...

Urban flooding has become an increasingly important issue in many parts of the world. In this study, an integrated flood assessment model (IFAM) is presented for the coastal urban flood simulation. A web based GIS framework has been adopted to organize the spatial datasets for the study area considered and to run the model within this framework. The integrated flood model consists of a mass bal...

Participants in the land market are usually hampered to browse and analyze the land price information due to the lack of information sources and available analysis tools. A service-oriented GIS-based web system was developed to provide a practical solution, its essential data sources contain basic geographic elements and benchmark land price (BLP)-related information. Core models for land price...
