List of principal and guide meridians and base lines of the United States

January 01, 1970

"Guide Meridian" redirects here. For the highway, see Washington State Route 539.

The following are the principal and guide meridians and base lines of the United States, with the year established and a brief summary of what areas' land surveys are based on each.

Figure 1. This BLM map depicts the principal meridians and baselines used for surveying states (colored) in the PLSS.

List of meridians edit

Primarily from the United States Government Printing Office Style Manual.[1] State names usually signify only parts of each listed state, unless otherwise indicated.

Based on the BLM manual's 1973 publication date, and the reference to Clarke's Spheroid of 1866 in section 2-82, coordinates appear to be in the NAD27 datum.
