America 2050
Megaregions of the United States are generally understood to be regions in the U.S. that contain two or more roughly adjacent urban metropolitan areas that, through commonality of systems—of transport, economy, resources, and ecologies—experience blurred boundaries between the urban centers, such that perceiving and acting as if they are a continuous urban area is, for the purposes of policy coordination, of practical value. The antecedent term, with which "megaregions" is synonymous, is megalopolis, which was coined in relation to the Boston through Washington, D.C., corridor in the Atlantic Northeast, by Jean Gottmann in the mid-twentieth century. ''America 2050'', a project of the Regional Plan Association, lists 11 megaregions encompassing urban regions in the United States, Canada, and Mexico (e.g., the Great Lakes and Northeast Megaregions). As of December 2000, these clustered networks of American cities contained an estimated total population exceeding 280 million p ...

The points of the compass are a set of horizontal, radially arrayed compass directions (or azimuths) used in navigation and cartography. A compass rose is primarily composed of four cardinal directions—north, east, south, and west—each separated by 90 degrees, and secondarily divided by four ordinal (intercardinal) directions—northeast, southeast, southwest, and northwest—each located halfway between two cardinal directions. Some disciplines such as meteorology and navigation further divide the compass with additional azimuths. Within European tradition, a fully defined compass has 32 'points' (and any finer subdivisions are described in fractions of points). Compass points are valuable in that they allow a user to refer to a specific azimuth in a colloquial fashion, without having to compute or remember degrees. Designations The names of the compass point directions follow these rules: 8-wind compass rose * The four cardinal directions are north (N), east (E), s ...
