Description: Future 2012 Oakland County Airport Noise Contours are shown as polygons. The noise contours were generated in Integrated Noise Model (INM) 7.0a, exported to DXF Lat/Log, reprojected in Autocad Map to stateplane, and then converted to ArcGIS geodatabase. The contours are labeled in a weighted decible measurement (DNL). The key field is Day Night Sound Level.
