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 available 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 2021 compiled datasets and graphs (420 MB).

2020 Airborne Electromagnetic Survey (AEM)

 

PDF The AEM data for the 2020 surveys are now available at the Nebraska GeoCloud (NGC): "https://snr.unl.edu/csd/geology/nebraskageocloud.aspx"). The NGC is a web-based digital platform for geophysical, geological, and groundwater data and models. The purpose of the NGC is to archive Nebraska’s vast volume of data and make it accessible to both model builders and model users.

The Nemaha and Papio-Missouri River NRDs conducted AEM flights in August 2020 using Water Sustainability Fund (WSF) grant dollars awarded in November 2019. ("https://nrc.nebraska.gov/water-sustainability-fund-0").

Datasets

Google Earth Datasets:

The interpreted results for the 2020 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 2020 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 broken into 8 parts for the grid-style and block area lines flown across the District. There are 445 associated image files (335 MB) linked to the data dots provided in the 8 area.kmz files.

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.

See the video tutorials on the top of the Media/Downloads Tab for detailed instructions. Google Earth will look here on your hard drive: C:\PMR20_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 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 "PMR20_Profiles" directly onto your C drive.

NOTE: You can view flight lines from some mobile devices if you have Google Earth but you need to use a Microsoft Windows computer to see the data and hot linked profile images.
