The U.S. Geological Survey (USGS) has released 2014 updates for North Dakota topographical maps. US Topo quadrangles (as they are called on the USGS website) are digital topographic maps produced by the National Geospatial Program of the U.S. Geological Survey (USGS) and are updated every 3 years. According to their website, the maps are created in the familiar 7.5-minute quadrangle format like the legacy paper maps, US Topo maps support frequent updating, wide and fast public distribution, and basic, on-screen geographic analysis.
US Topo maps are available for free Web download from the USGS Store. Once in the store, you can search for a place or address or use your mouse to mark points on the map. A list will pop up with potential matches in that area and you will have the option to view or download but the view is very small where the download is much easier to read. Each map is delivered in PDF format. The download will be a zip file that contains the PDF.
The site also includes some older maps that may be of interest to landowners. The older maps are not comprehensive but for some areas it may be possible to trace the changes and evolution of the landscape.
