Popis

This map layer includes Global Map data showing cities and towns in the United States, Puerto Rico, and the U.S. Virgin Islands. The data are a modified version of the National Atlas of the United States 1:1,000,000-scale cities and towns of the United States; those source data were derived from the Geographic Names Information System (GNIS) and the U.S. Census Bureau National Places Gazetteer files. Global Map refers to these locations as Built-up Area (point) and defines them as areas containing a concentration of buildings and other structures (smaller than Built-up Area (face)). National Atlas cities or towns are defined as places with a recorded population, usually with at least one central area that provides commercial activities. Cities are generally larger than towns; no distinction is made between cities and towns in this map layer. No attempt has been made to reconcile the Global Map and National Atlas feature definitions.
