Most cartographers will tell you that a map is only as good as the source information from which it is gathered. This United States map, first published in March of 1892, shows the US with an overlay describing the relative quality of source maps, or "Mother Maps" available at that time for various sections of the country. The map was painstakingly compiled by mapping pioneer Henry Gannett of the US Geological Survey.
The 1892 United States map features:• A US map showing the 48 states
• Color-coded areas depicting the quality of the "Mother Maps" available for each area
• Major cities and waterways
Coverage Area: United States, northern Mexico, southern Canada
