Abstract

This paper presents three Spatial Search Algorithms for determiningthe three dimensional visibility shape (threat dome) at a user’s current locationin a built environment. Users then utilize this 3D shape as their query“window” to retrieve information on only those objects visible within a spatialdatabase. Visibility shape searching addresses the information overloadproblem by providing “Hidden Query Removal” functionality for mobile LBS.This functionality will be especially useful in the Web 4.0 era when trillions ofmicro-sensors become available for query through standard IP access.
