Implementing an Augmented Scene Delivery System

Abstract. This paper addresses the core issues confronting the design and use of an augmented scene delivery system (ASDS). An augmented scene is a realtime, interactive, symbolized, perspective view of an environment that serves as a graphical index to an underlying spatial database. It allows a person in the field to interpret and navigate through the environment without reference to an external map. Augmented scenes will enable users with underdeveloped map use skills to effectively interpret and analyze their environment in professional, educational, and recreational contexts. This paper discusses an ASDS implementation that acquires imagery from a user-controlled webcam. It focuses on issues of data sampling and representation
