2014 NAIP Aerial Photography

The statewide 2014 imagery from the National Agriculture Imagery Program (NAIP) is available from the GIS Hub and from the U.S. Department of Agriculture Geospatial Data Gateway. This 1-meter pixel resolution aerial photography is in MrSID format, organized by county. 

To download the data from the GIS Hub, visit the Hub Data Portal then either browse within the Imagery category or simply type in 2014 in the What? field and click the Search button.  Click on the More Information button then scroll down to the Transfer Options section and click on the "Download USDA-FSA-APFO Aerial Photography 2014 MrSIDs" link. 

Please note that in early 2015 we plan to receive the 2014 imagery in a format that we can use to build a statewide mosaic that will be available as web services.

Dates for this and other imagery can be found on the GIS Hub Dates_Imagery service.  In early 2015 we should have the individual quarter-quad dates also available.

Updated Datasets on the GIS Hub

A number of datasets have been updated on the GIS Hub by the North Dakota GIS Technical Committee data stewards.  These are:

  • State and Federal Roads (updated, courtesy of the Department of Transportation)
  • Road Mile Markers (updated, courtesy of the Department of Transportation)

These datasets can be downloaded and/or delivered via data services.  More information on these datasets can be found on the Hub Data Portal. You can search for these datasets (e.g., type in: markers) or you may find it convenient to simply browse to the data within the Categories section of the Hub Data Portal. After you've located the data of interest, click on the More Information button and then scroll down to the Transfer Options section. In that section, click the Download link to download the data or click one of the other links such as the 'Esri REST including WMS' link to obtain the data service information.
