Historical Maps Are a Wealth of Information

How has this landscape changed over time?
Who has occupied this property?
What type of development has occurred?
What types of chemicals, petroleum products or other materials were used, stored, manufactured or disposed of in the past?

These are a few of the questions that historical maps can help answer. Our maps are provided in high-quality digital formats so you don’t miss any details about property occupants, landscape and the built environment.

All of our maps are in the public domain and not limited by copyright laws, so they can be easily reprinted for your reports or used in other ways. We’ve added many high-quality scans of Fire Insurance Maps to our collection. Read more about this project here.

Fire Insurance Maps

Fire insurance maps (FIMs) from the 1800s and 1900s show cities and other developed areas and they include details such as:

  • building size and construction, location of roads, railroad tracks and shorelines
  • building occupants and property uses at the time the map was prepared
  • the location of fuel, chemicals and other possible fire or explosion hazards

From these historical maps you can understand the construction of old buildings and what was present on properties in the past. You will note the location of wells, storage tanks containing chemicals and petroleum products. Plus, you will gain an understanding of former property uses based on business names and the equipment and materials used in the buildings at the time the maps were prepared.

We have a wide range of urban and rural coverage across the United States, and most maps are in high-resolution color where available. Some publishers of the maps in our collection include:

  • Sanborn Map & Publishing Co.
  • Sanborn-Perris Map Co.
  • Sanborn Map Co.
  • Fire Underwriters Inspection Bureau
  • Rascher Insurance Map Publishing Co.
  • General Inspection Bureau
  • Charles S. Yerkes

Atlases and Plat Maps

These include:

  • city atlases
  • county atlases
  • real estate atlases
  • plat maps for counties and municipalities

These maps may show property owner names, lot lines, streets and other features of the built environment. Some of these maps are in color and some show details similar to fire insurance maps such as buildings and other structures, construction materials used in structures and occupant names.

Some of the resources we have built our collection from include:

  • U.S. Work Projects Administration
  • Nirenstein’s National Realty Map Co.
  • C.M. Foote & Co.
  • G.M. Hopkins
  • Minneapolis Real Estate Board
  • David L. Curtice
  • H. Donnelly


Topographic Maps

At times the only map source for a property will be topographic maps. These maps were first published in the 1800s and now cover the entire United States. Topographic maps show natural features such as:

  • lakes and rivers
  • wetlands
  • topographic relief

Cities and towns are depicted along with individual structures in rural areas and man-made structures such as roads, railroad tracks, dams and bridges. Certain land disturbance activities such as quarries, mines and ditches are often shown.

We provide unified digital copies of current and historical 7.5 and 15 minute USGS topographic maps for the entire United States. All topographic maps are in color and include a scale bar. Your site is centered on each unified map and all map years are identified.

Just a few resources of the historical topographic maps in our collection include:

  • City of Minneapolis
  • City of St. Paul, MN
  • Various Commissioned Projects
  • Mississippi River Commission
