Example Declination Value
Magnetic declinations are east (positive) if the compass measures east of true
North, and west (negative) if the compass measures west of true North.
At the time this manual was published, Denver, Colorado, which is in the western
part of the continental US, had a declination value of 8°49
east, which is
represented as a positive value. The zero declination line runs generally north and
south somewhere west of Chicago.
Online Declination Software
NOAA's National Geophysical Data Center (NGDC) website includes online declination
software that computes the estimated declination for your location. You only need to enter
the location (US zip code) and date of interest.
At the time this manual was published, the website address was:
http://www.ngdc.noaa.gov/geomagmodels/Declination.jsp.
Although the software is setup for US zip codes, it also provides a link
for locations outside of the USA.
