The 2020 Airborne Electromagnetic (AEM) Survey Flight reports for the Nemaha and Papio-Missouri-River NRDs are complete! You can also click here for an updated location map of the eastern Nebraska 2006 to 2020 flight locations. A statewide interactive map of all flight lines is available here. Digital polyline files are available on the AEM tabs and at the bottom of the AEM Project Partners Tab. New tutorial video links demonstrating the download and use of the report deliverables are also availiable on the Media/Downloads Tab as well as other ENWRA project reports. Be sure to visit our other website tabs and the Nebraska GeoCloud website for more information on statewide AEM data availiability, guidelines and standards.

Groundwater elevation, weather station data and sampling results for ENWRA's 3 pilot study sites are now available under the Media/Downloads Tab. Click here for a link to download the 2008 to 2020 compiled datasets and graphs (345 MB).

2018 Airborne Electromagnetic (AEM) Surveys

The summer 2018 AEM flights are now complete! The six eastern Nebraska Natural Resources Districts (NRDs) conducted AEM flights this June through late July 2018 using Water Sustainability Fund (WSF) grant dollars awarded in November 2017 ("https://nrc.nebraska.gov/water-sustainability-fund-0").

PNG Play AEM Overview

The Lower Platte North, Lower Platte South, Papio-Missouri River, Lewis and Clark, Lower Elkhorn, and Nemaha NRDs each had a mix of the following types of surveys in eastern Nebraska:

The preflight work was very critical the success of the AEM survey and included the following planning activities: mapping out flight lines to avoid infrastructure and potential interferences (approximately 11,000 line kilometers/6,835 miles), equipment/personnel mobilization, helicopter fueling and ferrying logistics, background data gathering, submission of news releases to the media and general public, and contracting.

The first chapter report providing the survey results within the Lower Elkhorn NRD was completed on December 31, 2018. The remaining NRD chapter reports were delivered throughout 2019 with the final chapter report for the Lower Platte South NRD completed December 4, 2019. Download links for the NRD chapter reports are available on this page see below.

Datasets

Google Earth Datasets:

The interpreted results for the 2018 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 from ENWRA's Dropbox.

The link above provides ".kmz" files that will show the 2018 AEM flight lines "as flown" and where data was chopped out from interferences ("retained") as well as ".kmz" files that show attributed data dots in Google Earth you can click on. The attributed ".kmz" files are provided in 8 parts (broken up for faster viewing). There are 153 associated image files (300 MB) linked to the data dots, plus a separate folder for the tighter spaced lines flown in the Pierce, Nebraska area with 45 associated image files (83 MB) and a "PierceCoBlock_Interp_v5.kmz" file.

You can select "no thanks" to the sign-up for a Dropbox account and still download the files (upper right, download button shown below). 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 onto your computer's C drive. Google Earth will look here on your hard drive: C:\LENRD18_Profiles\ or here: C:\Pierce_Profiles\ for every profile image when you touch a link on a data dot - see example image below. An easy way is to do this is to create folders named "LENRD18_Profiles" and/or "Pierce_Profiles" directly on your C drive, download and unzip the Dropbox files wherever your browser typically puts downloaded files, and then cut, copy or drag all the downloaded, unzipped files to those corresponding LENRD18_Profiles and Pierce_Profiles folders you created on your C drive.

NOTE: You can view flight lines from some mobile devices if you have Google Earth but you need to use a computer to see the data and hot linked profile images. Warning these Google Earth files, if downloaded, may use up to 0.3 GB of your mobile data.

An easy way is to do this is to select direct download at the upper right from the Dropbox link and then go unzip the Dropbox file wherever your browser typically puts downloaded files (right click and hit extract). Once the folder has been unzipped then cut, copy or drag the unzipped file folder called "NNRD18_Profiles" directly onto your C drive.
