Geographic Hypermedia System Model Design and Application

Zhigang Hana, Caihui Cui, Yunf

Abstract

Geographic Hypermedia (GH) is a rich and interactive map document with geo-tagged graphics, sound and video ele-ments. A Geographic Hypermedia System (GHS) is designed to manage, query, display and explore GH resources. Recognizing emerging geo-tagged videos and measurable images as valuable geographic data resources, this paper aims to design a web-based GHS using web mapping, geoprocessing, video streaming and XMLHTTP services. These data can be integrated in HTML pages or used as Rich Internet Appli- cations (RIA) using standard web technologies such as the AJAX, ASP.NET and RIA frameworks. An SOA-based GHS is designed using four types of web services: ArcGIS Server 9.3 web mapping and geoprocessing services, Flash FMS 3.0 video streaming ser- vices and GeoRSS XMLHTTP services.
