An augmented scene delivery system (ASDS) creates and distributes annotated cartographic products in real time from captured still imagery. An ASDS applies augmented reality technology to the visualization of unrestricted exterior viewsheds through an adaptive, perspective-based surface resampling model. This paper describes an ASDS testing platform, introduces a client/server model for distributing augmented scenes over the Internet, presents a linear-time algorithm for resampling dense elevation models for perspective imaging and conducts an execution analysis of the algorithm's implementation, demonstrating that augmented scenes can be constructed and delivered efficiently. The paper also presents a migration path to mobile ASDS platforms with a discussion of the remaining technological problems associated with its implementation.
