Handling and sharing geospatial data from etherogeneous sources in a collaborative way can be addressed by a WebGIS platform, built with open source components. An important role is played by open standards, metadata and open source (OSS) architectures, which we review in the present paper. We introduce Anteo, a WebGIS realized with standard and open software technologies, devoted to exchanging...

on the basis of shortage existing in current meteorological integrated display system, this paper introduces an open source framework of Mapserver, discussed the construction mechanism of WebGIS development based on it. A client solution based on it has been implemented in order to provide a WebGIS environment for multi-source meteorological data. The results showed that the new constructed sys...

This paper discusses how to provide spatial analysis for XML/GML/SVG based WebGIS. In recognition of current XML/GML/SVG based WebGIS’s insufficiency of providing spatial analysis, we focus on two important issues. First, based on the theory of spatial data modeling, we propose an SVG-based spatial information representation model to represent the needed spatial data in SVG on the browser side....

Based on the actual needs, it is to explore the application for rescuing emergency combined with data mining and webGis technology. Give out the data mining based on the previous emergency-related data, and then establish the early warning models. It provides the practical application as a part of the social services by applying the forecasting analysis for early warning with the help of some p...

The usage of 3D models acquired from airborne and terrestrial laser scans within a web-based GIS environment allows a new way to conduct archaeological research but also demands new approaches and concepts in the development of infrastructure that supports such research. This article gives an overview of a design and prototypical implementation of a 4D-webgis for archaeological research. The in...

WebGIS tools have the potential to disseminate the outputs of spatial vulnerability assessments to a wide range of communities, including public health decision-makers. Based on a previous assessment of socioeconomic vulnerability to dengue fever in Cali, Colombia, we developed and used a WebGIS tool to facilitate the visualization, exploration and dissemination of prevailing vulnerabilities to...

This paper proposed a WebGIS-based, template oriented and on-line group spatial decision support system for Investment Environment analysis. This system provides online mapping, online spatial and non-spatial information query and online multi-criteria evaluation through Internet by integration of WebGIS and analytical module. Template servers as the “smart agent” between user and system, it pr...

A practical hierarchical component-based WebGIS model referred to as Geo-Union is presented. Geo-Union consists of four layers: storage layer, service layer, component layer and application layer. Service layer is partitioned into another two layers: Geo-Union client and Geo-Union server. The architectures and object diagram of each layer in Geo-Union are discussed in details. After that, four ...
