The last four years has seen a dramatic improvement in the power and availability of visual computers. Coupled with this development is the equally impressive rise of the Internet, whereby virtually any computer can be connected to a vast global network. The 3D GeoEye project hopes to harness these two advances towards the development of a 3D, web-based query engine. With 3D GeoEye, a user could first view a 3D computer generated world, then interact and use the environment to access a remote database; all within in a seamless, platform independent display and query system.
Development of the 3D GeoEye will focus on five key areas: data acquisition, data management, data transfer via the Internet, data visualization and, and remote database query. Attention will be directed towards converting 2D CAD based drawings, vector maps, DEMs and images into efficient integrated 3D models. The vast needed to sustain a virtual world will have to be transferred very quickly over remote networks, therefore an investigation into data compression and optimization is required. The data then must be displayed on a wide variety of platforms and at comfortable speeds for the user. Java 3D and Open GL promise effective and readily available solutions. Finally, the user must be able to query a database using the 3D model. JDBC/ODBC promises to bridge the gap between the 3D world and the wealth of information database
