Google Earth

The FAA has released Final EA information on the DEN Metroplex Project on November 18, 2019 that updates and supersedes previously released DEN Metroplex Draft EA information. The Final EA Google Earth format files are released and this information can be accessed below. Due to size, the files may take more than a few minutes to load into Google Earth.

Internet Explorer and Mozilla Firefox – Select the file you wish to view from the list below. If you have Google Earth installed on your computer, your browser should prompt you to select 'Open' when you click the link. If you do not have Google Earth installed on your computer, click here to download it

Google Chrome – Select the file you wish to view from the list below. Your browser will automatically download the file. Open your downloads folder and click on the file. The file should open in Google Earth. If you do not have Google Earth installed on your computer, click here to download it.

In Google Earth, expand the folder tree by clicking on this icon . Turn layers off and on by clicking the box next to the file name.
To pan to your address, type an address into the search box in Google Earth. Google Earth will zoom to that address. Otherwise, use your mouse to pan and zoom in to areas you are interested in. Click the flight path/gridpoint layers on and off to identify data most relevant to that location. Click the individual grid points to activate pop-up boxes with the noise analysis results for that location.
For more information on Google Earth files, please see this video on the SoCal Metroplex page here.

Please note that the Proposed Action (PA), No Action (NA), and Change in Value (PA-NA=X) DNL values associated with each grid point may not appear to add up due to rounding.
