In TowerCoverage.com you are able to add Overlays to you account. There are some overlays already in the site that are there for everyone but you can also add your own overlays that are specific to your account. The overlays must be KML format and no greater than 3MBs. This allows you to use other software, such as Google Earth and lay out locations that are relevant to your company, such as office locations, customer locations or fiber routes of your network.
You can then place these overlays into your TowerCoverage.com account and view them from any of your Coverages or Multi Coverages! The Below image is an example of a hiking trail that has been added to TowerCoverage.com.

Adding Overlays

To add overlays to you account you will need to be logged in as the admin of the account. Once logged in you can go to My Account in the upper right of your Dashboard. On the left of your account management screen you will see the tab for Overlay Management.

Once you are here you can add you overlays. As stated before, the files musts be in a KML/KMZ format an you will need to name the overlay. All Overlays that you upload into TowerCoverage.com will then become available via your Coverage Map.

Viewing Overlays

After you have added your overlays you can open you coverage, on the left side of the map is located the map tools. Here you can select Overlays. The drop down menu will open that contains all of your overlays as well as the default overlays that are already in TowerCoverage.com.
