Ontology Driven Visualisation of Maps with SVG - An Example for Semantic Programming

Tenth International Conference on Information Visualisation (IV'06), 2000

In this work we demonstrate a particular use of ontologies for visualising maps in a browser window. Geographic data are represented in the OWL data format that corresponds to an ontology of transporation networks which was designed in close relation to the concepts of the Geographic Data Format (GDF). These data are transformed into Scalable Vector Graphics (SVG). The transformation is specified symbolically as instances of a transformation ontology. This approach is extremely flexible and easily extendible to include all kinds of information in the generated maps. The basic implementation technique is to use classes and instances of ontologies in an intelligent way.

SVG-based spatial information representation and analysis

2008

This paper tries to make some spatial extensions to W3C's Scalable Vector Graphics (SVG) Specification to support SVG-based spatial information representation and analysis in the Web environment. Based on spatial data modeling, this paper attempts to find a theoretical foundation for SVG-based spatial information representation. Then we propose an SVG-based spatial information representation model for spatial data publishing.

An SVG-based method to support spatial analysis in XML/GML/SVG-based WebGIS

International Journal of Geographical Information Science, 2011

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. Furthermore, this paper designs and implements some spatial operators and integrates them into a Spatial Extended SQL (SESQL) to support spatial query and analysis on spatial data which is represented in GML/SVG. This method can greatly improve the functions of current XML/GML/SVG based WebGIS applications, most of which have been only employed for visualization. Finally, this paper designs some case studies. The results of the case study prove that the suggested method is feasible and operable for providing spatial analysis in XML/GML/SVG based WebGIS.

A Holistic Approach of Map Composition Utilizing XML

The explosion of Internet technologies causes an increasing demand for maps on the web. A number of web mapping and cartographic sites include on-line applications that generate maps using server technologies. However, most of the presented maps are of fairly low cartographic quality and very limited interaction. The arising of SVG technology breaks this lack of standardized client-side vector display. For the first time, SVG allows for high quality cartographic elements with interaction and animation, implemented using standardized programming languages and grammars. As the Web has grown in popularity and complexity, users and content providers have demanded more Web sites and visual sophistication. The low-resolution GIFs that populate Web pages today have limited capabilities. SVG is based on Extensible Markup Language (XML), a new standard for creating Web pages that provides the tools needed to go further. This paper describes the way spatial data is stored in an object-oriented environment and subsequently translated, in order to be used for the composition of maps/charts on the Web and open environments. The World Wide Web is fast becoming a standard platform for Geographic Information Systems. Commercial developers are already producing on-line versions of their GIS software. The development of open source software to support this kind of applications remains a challenge that can be tackled with the utilization of XML, which underlies just about all of the current standards for "open" environments.

A logic for SVG documents query and retrieval

Multimedia Tools and …, 2004

We propose a knowledge representation approach to the semantic retrieval by content of graphics described in Scalable Vector Graphics (SVG), the novel XML based W3C approved standard language for describing two-dimensional graphics.

A cartographic approach of the process of map symbolization on gvSIG software

Maps are very important in many studies related to different fields including geography, history, education etc. The process of map design is an important function of a GIS software. The gvSIG project is one of the open source geospatial tools that can be used in order to visualize different types of spatial phenomena related to geographic space. The development of each open source project is mainly based on the contribution of its user's community. The aim of the present paper is to summarize the fundamental principles related to map symbolization and to provide some critical indications for the improvement of map symbolization in gvSIG.

SVG STANDARD FOR ENVIRONMENTAL APPLICATIONS

This paper proposes the use of SVG standard for environmental applications through on-line generation of maps that can be visualized in browsers. Recently, web-based GIS with the rapid expansion of internet and the World Wide Web is regarded as one of important issues for web application, and several GIS products running on web browser have been announced. The system used in this study has two main differences from other web-based GIS applications. It's real-time and gets data from sources simultaneously in exact time intervals that users defined previously, and secondly, all the developing and publishing tools used in the system are open sourced. Aim of this study is to create a web-based, free and open sourced GIS that can work with different data formats by exchanging and presenting data as a real-time map on web.

An XML-based approach for the composition of maps and charts

Proceedings of the 21st International …, 2003

Traditional" approaches for the storage and composition of maps/charts on the Web, involve the utilization of commercial geographic/cartographic systems and databases structured and built around a Relational Data model. These approaches impose a number of limitations on the users, the data and the way maps/charts are composed.
