Customizable landscape visualizations. Implementation, application and testing of a web-based tool
This paper describes a new approach to delivering visualizations of Digital Elevation Model (D.E.M.) data over the World Wide Web. The delivery system described uses state-of-the art Java technology to deliver landscape visualizations, in both two (2D) and three (3D) dimensions, that are unique for each user of the service. An example is given of the use of this service as a teaching aid. A thin client approach is used to allow the final service to be accessible, both in terms of delivery speeds and user interface, to the maximum number of non-geospatially aware users. The landscape server conforms to the OpenGIS web map server specifications. The service is live at: http://tsunami.geo.ed.ac.uk/?kwm/landscapes/
