The Atlas presents in maps and text complete data about the creation and all subsequent changes (dated to the day) in the size, shape, and location of every county in the fifty United States and the District of Columbia. It also includes non-county areas, unsuccessful authorizations for new counties, changes in county names and organization, and the temporary attachments of non-county areas and unorganized counties to fully functioning counties. The principal sources for these data are the most authoritative available: the session laws of the colonies, territories, and states that created and changed the counties.

Distorting space to better visualize travel time / itineraries.

The Tabula Peutingeriana is the only known surviving map of the Roman cursus publicus; it was made by a monk in Colmar in the thirteenth century. It is a parchment scroll, 0.34 m high and 6.75 m long, assembled from eleven sections, a medieval reproduction of the original scroll. It is a very schematic map: the land masses are distorted, especially in the east-west direction. The map shows many Roman settlements, the roads connecting them, rivers, mountains, forests and seas. The distances between the settlements are also given.

The table appears to be based on "itineraries", or lists of destinations along Roman roads, as the distances between points along the routes are indicated.[5] Travelers would not have possessed anything so sophisticated as a map, but they needed to know what lay ahead of them on the road and how far. The Peutinger table represents these roads as a series of roughly parallel lines along which destinations have been marked in order of travel.

Google’s apparent geographic illiteracy is a screw-up of major magnitude. Advertisers are not getting their money’s worth because their ads are showing up in the wrong geography. People cannot find the places to which they want to navigate, because Google cannot tell them where the location is on the surface of the earth. Communities that rely on Google Maps to help people find and navigate to their city facilities cannot depend on the maps they serve to show the actual location of the city.
