U.S. National Grid Maps for Minnesota

Reference maps covering Minnesota, based on the U.S. National Grid system, show the location of schools, hospitals, fire and police stations, roads and political boundaries over an air photo background.

The USNG is a standard location reference system that does not depend on landmarks or street signs. It is an efficient way to provide location information at different levels of detail and across administrative and political boundaries. The USNG is particularly useful in emergency situations.

The maps can be viewed online or downloaded and printed.

  • 10K grid:  The state is divided into a grid of squares that are 10,000 meters on a side ("10K" for short); each map covers one of these squares. At this scale, about 2,000 maps are needed to cover Minnesota.
  • Scale and print size:  The maps are fixed at a scale of 1:24,000 for a print size of 22 by 24 inches.
  • GIS Data and ArcMap .mxd files:  The GIS data (structures, USNG grid, etc.) and Esri ArcMap v. 10.0 .mxd files used to create these maps have been bundled as a single compressed (.zip) file for download named "MnGeo_USNG_10K_Map_Data_Mxds.zip". Please refer to the instructions, "MnGeo_MSC_Create_USNG_10k_Maps_2012_12_20.pdf", which are also included in the .zip file.
