2016 Airborne Electromagnetic Survey (AEM) Flights

Papio-Missouri River___Lewis & Clark___Lower Elkhorn___Lower Platte North___Lower Platte South


The summer 2016 AEM flights are complete! Several Natural Resources Districts (NRDs) across the state conducted AEM flights this July and early August 2016 using Water Sustainability Fund (WSF) grant dollars awarded in April 2016 ("https://nrc.nebraska.gov/water-sustainability-fund-0").

The Lower Platte North, Lower Platte South, Papio-Missouri River, Lewis and Clark, Lower Elkhorn, Upper Elkhorn, Lower Loup, and Lower Niobrara NRDs each have a mix of the following types of surveys flown in eastern Nebraska:

Click here to watch Omaha Channel 6 WOWT video coverage of flights in Sarpy County Nebraska in late July in the Papio-Missouri River NRD.

The preflight work which was very critical the success of the AEM survey included the following planning activities: mapping out flight lines to avoid infrastructure and potential interferences (approximately 6,000 line kilometers/3,728 miles), equipment/personnel mobilization, helicopter fueling and ferrying logistics, background data gathering, submission of news releases to the media and general public, and contracting. Presentations and final reports for the 2016 Surveys are scheduled for completion by the end of 2017. ENWRA has tentwtive plans for additional surveys in 2018 (See preliminary blue lines on the project map above)

Datasets

Google Earth Datasets:

The interpreted results for the 2016 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 file and associated image files, 80.5 MB) 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 "GoogleE_README.pdf" PDF 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:\Sarpy_Profiles\ for every profile image when you touch a link on a data dot - see example image below. The easiest way is to do this is to create a folder named "Sarpy_Profiles" directly on your C drive and then save all the downloaded dropbox files to that folder.

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.
