Panoramic Maps Collection. Geography and Map Division, Library of Congress.
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.
You will find here fascinating panoramic maps of Michigan that can be zoomed in on to see the fine details. There is a map of Grand Rapids from 1868, about the time Caledonia was formed.
