Development of web portals concerning spatial information

Abstract

Nowadays almost all companies, public authorities or other institutions have developed some kind of web-application to present their information to dedicated end users. The different implementations range from simple static HTML pages to dynamically information generated for each request at runtime. A lot of applications additionally need to integrate spatial data. As these kind of information are somehow different from other data, the integration, administration and presentation is not as easy as in traditional web applications. This paper gives an overview how we handle spatial information in the MobiHarz project 1. As this architecture completely consists of free software, parts of the system can easily be adopted to other spatial applications on the web. Especially public authorities shall be encouraged by this article to use freely available software in spatial information systems.
