Panoramic maps were 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.
Preparation of panoramic maps involved a vast amount of painstakingly detailed labor. For each project a frame or projection was developed, showing in perspective the pattern of streets. The artist then walked in the street, sketching buildings, trees, and other features to present a complete and accurate landscape as though seen from an elevation of 2,000 to 3,000 feet. These data were entered on the frame in his workroom.
The post-Civil War town views are more accurate and are drawn from a higher oblique angle. Panoramic mapping of urban centers was unique to North America in this era. Most panoramic maps were published independently, not as plates in an atlas or in a descriptive geographical book. Preparation and sale of nineteenth-century panoramas were motivated by civic pride and the desire of the city fathers to encourage commercial growth.
Panoramic maps not only showed the existing city but sometimes also depicted areas planned for development (like the temple on this map). Advances in lithography, photolithography, photoengraving, and chromolithography, which made possible inexpensive and multiple copies, along with prosperous communities willing to purchase prints, made panoramic maps popular wall hangings during America's Victorian Age.
Augustus Koch created this 1870 view of Salt Lake City and it was published by the Chicago Lithographing Company.
