Abstract
The present invention includes a method for dynamically updating a propagation model of communication signals in an area being subjected to earthworking operations which alter the topology of the terrain in which the method comprises the steps of dynamically updating a terrain map of the area as a function of the earthworking operations and dynamically updating the propagation model in response to updating the terrain map. An apparatus for dynamically updating a propagation model of communication signals in an area being subjected to a mobile geography-altering machine capable of altering the topology of the terrain, the apparatus comprises circuitry for storing a terrain map representative of the terrain prior to the terrain being subjected to alteration by the mobile geography-altering machine, circuitry for dynamically updating the terrain map as the terrain is being subjected to alteration by the mobile geography-altering machine, and circuitry for dynamically updating the propagation model in response to updating the terrain map.
