Cities and Towns
These maps depict a range from individual buildings to panoramic views of large urban areas. They record the evolution of cities illustrating the development and nature of economic activities, educational and religious facilities, parks, street patterns and widths, and transportation systems.
Panoramic Maps
The panoramic map was a popular cartographic form used to depict U.S. and Canadian cities and towns during the late nineteenth and early twentieth centuries. Known also as bird's-eye views, perspective maps, and aero views, panoramic maps are nonphotographic representations of cities portrayed as if viewed from above at an oblique angle. Although not generally drawn to scale, they show street patterns, individual buildings, and major landscape features in perspective.

Sanborn Maps

The fire insurance maps produced by Sanborn show building footprints, building material, height or number of stories, building use, lot lines, road widths and water facilities. The maps also show street names and property boundaries of the time. This collection of maps is historically significant as it is sometimes the best detailed map of a town or city dating from the mid 1800s.
