2012 NAIP Aerial Photography

The statewide 2012 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 2012 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 2012 MrSIDs" link. 

Please note that in early 2013 we plan to receive the 2012 imagery in a format that we can use to build a statewide mosaic that will be available as web services.

Updated Dataset on the GIS Hub

One of the GIS Hub datasets has been updated by a North Dakota GIS Technical Committee data steward:

City and County Roads (NDDOT)

This data has undergone major work.  From the metadata:

"City streets were updated in Bismarck, Dickinson, Minot and Williston. GIS data from the City of Bismarck was used to update Bismarck, GIS data and 2012 aerial photography was used to update the city of Williston, Minot’s city map and the 2010 aerial photography from Ward County was used to update Minot, and 2011 aerial photography and Dickinson’s "working" city map was used to update Dickinson. The counties updated were Williams, Burke, Bottineau, Mountrail, Ward, Wells, Eddy, Foster, Griggs, Steele, and Cass. At the time of this update, approximately 50% of Stutsman and 50% of Traill Counties are updated. Williams, Bottineau, Ward, and Mountrail roads were inspected from the air and the 2009 NAIP photos were also used to assist the updates. The roads in Williams County were also recoded to match Williams County naming conventions. Williams County CADD map which is on the Williams county web site was used in updating the road names. In Ward County, the 2010 image from Ward County was used to assist in updating Ward County. The 2010 NAIP photos were used to update Wells, Eddy, Foster, Griggs and Steele Counties. Cass was updated with the assistance of the Cass County GIS layer and the 2011 Cass county imagery."
