vehicle similarly a wooded hill may have a lower value compared to a rocky hill because trees are more likely to dampen and or block noise emitted from a vehicle whereas rock formations are more likely to amplify and or propagate noise emitted from the vehicle atmospheric conditions module 1340 comprises data 1345 representing a model of the current weather conditions of the geographic area s stored in map module 1320 the data may represent the wind velocity and direction air temperature air density air pressure turbulence humidity precipitation water temperature water current velocity and direction depth of water and or any other condition that may amplify dampen block and or propagate sound emitted from a vehicle similar to terrain module 1330 each atmospheric condition is assigned a value or indicator based in its ability to amplify dampen block and or propagate sound emitted from a vehicle in one embodiment atmospheric conditions module 1340 is a weather research and forecasting wrf module that may be scaled into nested grids by a nested grids algorithm 1347 for one or more of the geographic areas stored in map module 1320 in another embodiment atmospheric conditions module 1340 is in communication with an external data source not shown and is configured to retrieve the current weather conditions of a geographic area from the external source and assign the appropriate value to each weather condition processor 140 may be any hardware device logic and or firmware capable of executing computer code computer instructions computer modules and or computer programs in one.
