Summary

This layer contains urban areas around the world. This polygon file is intended for medium scale thematic mapping and analysis.

Description

            

The spatial data were obtained from Natural Earth. The data originated from the 2002-2003 MODIS satellite data at 1 km resolution. The data are suitable for making relatively generalized maps of countries and regions and are intended for use at a scale no larger than 1:50,000,000. Attributes were modified to include scalerank, type, and area in square km. The coordinate system of this data is WGS 1984.
