png If you already have a folder named "LENRD_2014" on your C drive, please replace any existing .kmz files downloaded prior to April 2019. A Google Earth Pro update in early 2019 rendered the image links in the older .kmz files inoperable (impacts 2014-2015 AEM flight deliverables only).

Google Earth Datasets:

The interpreted results for the 2014 AEM flights have been provided in Google Earth format. You can download the free version of Google Earth Pro by clicking here. Click here for a link to download the Google Earth datasets (.kmz files - repaired April 2019) from ENWRA's dropbox (you can select "no thanks" to the sign-up for a dropbox account and still download the files). You must have Google Earth installed on your computer before downloading or opening the .kmz Google Earth dataset files.

If you already have a dropbox account, please choose direct download to your computer so you do not fill up space on your personal dropbox.

Please follow the instructions in the "read_me.txt" text file on Dropbox here AND save the downloaded files with the same exact file structure as shown on the dropbox. Google Earth will look here on your hard drive: C:\LENRD_2014\Profiles\ for every profile image when you touch a link on a data dot - see example image below). All files must be unzipped in order to work in Google Earth.

Google Earth Tips and Tricks: Grab the map with your cursor and hold down the "u" key on your keyboard to view the earth looking straight down instead of at an angle. Do the same and hit the "n" key to orient the map north as up. Google Earth Pro (link above) is free and you can hit the file menu, then hit open, and then select all data import formats from the dropdown and open an ESRI shapefile or many other GIS file types in Google Earth directly from a saved location on your computer.
