LOGIS GIS Produces Standard USNG Map Books for Member Cities
By Ben Verbick, LOGIS GIS
One of the many ways LOGIS GIS assists our public safety group and other emergency responders from our member cities is through the compilation and delivery of paper and digital map books, or “cab books”. These map books, used for reference by staff in the field, are specific to the jurisdictions of the cities and have, in recent iterations, been designed with the U.S. National Grid system as the primary focus of the page layout.
The U.S. National Grid (USNG) is based on a common geographic projection and rectangular grid system (Universal Transverse Mercator). Distances can be accurately measured between two locations easily, and the precision of locations and measurements can be maintained consistently across the state and across the nation.

The books are intended to be used primarily by fire and police departments, especially for disaster response and damage assessment, but are also used by public works and utility staff. Each page includes one 1000m USNG location. Depending upon a municipality’s available data, the maps include these standard layers: parcels, house numbers, parks, street centerlines, hydrants, fields (play fields, other open space, empty lots), paths, parking lots (curbing if available), lakes, 100m USNG, rivers/streams, building footprints (if available), and schools. A standardized system of colors and symbology are used. The bold black numbers and lines show the USNG 1000m grid, and the thinner black lines show the 100m grid.
The compilation of our USNG books has been a collaborative effort. LOGIS GIS staff solicited assistance in sheet layout, design, and national compliance requirements from the city of Edina’s GIS staff, and we acquired USNG data source information from Dakota County’s Office of GIS as well as other sources. LOGIS GIS then compiled and delivered comb bound paper copies of the books to several of our GIS member cities and has created digital pages of the books for all of our GIS member cities. Since many of the map layers of these books are updated regularly for a variety of other city GIS needs, the compilation procedure has been embedded in our enterprise GIS. In this way, LOGIS GIS, city, and agency staff can quickly and easily reproduce up-to-date replacement pages for their books whenever necessary.
