Abstract
The present invention is a method for providing rapid intervisibility determination in resource-constrained computational environments. The method may be applied to various real-time applications, such as real-time flight planning and ad-hoc network management. The method includes pre-processing terrain elevation data into an ELDETREE data structure, which uses a 3-D grid coordinate system for each zone inside a multi-zone planning area, for expediting intervisibility determination. Along with promoting increased intervisibility computation efficiency, the method further promotes reduced memory usage for intervisibility computation.
