This paper presents three Spatial Search Algorithms for determining the three dimensional visibility shape (threat dome) at a user's current location in a built environment. Users then utilize this multifaceted 3D shape as their query "window" to retrieve information on only those objects visible and stored in a spatial database. Such visibility shape searching addresses the information overload problem by providing "Hidden Query Removal" functionality for mobile LBS applications. This functionality will be especially useful in the Web 4.0 "Future Internet of Things" era when trillions of micro-sensors placed throughout our built environment become available for discovery based on their geo-referenced IP address. In this paper we present and evaluate the effects that variations in mobile 3D query algorithms have on query speed vs. accuracy.
