Summary

This layer contains latitude and longitude graticule lines measured in 15 degree increments. This polygon file is intended for mediumscale thematic mapping and analysis.

Description

            

The spatial data were obtained from Natural Earth. The latitude reference lines include the Equator and the longitude reference lines include the Prime Meridian and International Date Line. Attributes were modified to include code, and east, west, north, and south coordinates. The coordinate system of this data is WGS 1984.
