Maps take many forms and many features are rendered. Typically, they fit into the following categories:

  • topographical
  • census
  • soil/mineral
  • historical
  • political
  • geographic
  • aerial
  • flood
  • insurance
  • specialty

Topographic maps show both natural and manmade features, including mountains, valleys, rivers, vegetation, roads, boundaries and major buildings. The U.S. Geological Survey (USGS) produces topographic maps for the entire United States. The best known maps are the 1:24,000-scale maps known as 7.5 minute quadrangle maps. Each map covers an area of 7.5 minutes of longitude. These maps are useful and popular primarily for recreational purposes. BPL owns copies of all the 7.5 quads for Idaho. They are available at the 3rd floor reference desk.

Geologic maps feature the distribution of rock formations, faults, and other geologic features, often superimposed in colors over a "base map" which is provided for location purposes. An example of such a map is the Geologic map of the Baker Peak quadrangle, Blaine and Camas Counties, Idaho / by David E. Stewart, [et al.] published by the Idaho Geological Survey. The library owns over 70 geologic quadrangle maps for Idaho.

And example of a mining map is Mines and Prospects of the Boise quadrangle, Idaho / compiled by William B. Strowd ... [et al.] published by the Idaho Bureau of Mines and Geology RNW 551 Mines

Flood Insurance Rate (FIRM) Maps RNW 368.122 UNITED BOISE CI are the official maps of communities on which FEMA has specifically identified both special hazard areas and risk premium zones. The purpose of the FIRM is to rate flood insurance policies through the National Flood Insurance Program. Based on hydrologic studies where engineers attempt to determine how high water might rise and how often it could reach such heights. The 100 year flood is a flood that hydrologic engineers estimate has a 1% chance of occurring in any given year. This is also known as the base flood. The most recent Boise FIRM maps now cover Ada County.
