摘要：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 *** 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 *** concept,data model,system design and implementation of this GHS are discussed in ***-tagged videos are modeled as temporal,spatial and metadata entities such as video clip,video path and frame-based ***,geo-tagged stereo video and derived data are modeled as interre-lated entities:original video,rectified video,stereo video,video path,frame-based description and measurable image(rectified and disparity image with baseline,interior and exterior parameters).The entity data are organized into video files,GIS layers with linear referencing and XML documents for web *** data can be integrated in HTML pages or used as Rich Internet Appli-cations(RIA)using standard web technologies such as the AJAX,*** and RIA *** 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 *** applications in road facility management and campus hypermapping indicate that the GH data models and technical solutions introduced in this paper are useful and flexible enough for wider deployment as a GHS.
