You really should make sure that your data includes an "as of date" as magnetic declination actually changes constantly (though slowly). Note that there are two models referenced depending upon the date you are interested in.</P> <P>&nbsp;</P> Wed, 26 Apr 2017 14:56:44 GMT ballardw 2017-04-26T14:56:44Z https://communities.sas.com/t5/SAS-Programming/Magnetic-declination/m-p/353656#M82562 <P>Hello.</P><P>Is there a way to calculate the magnetic declination of a specific location?&nbsp; I am looking to pull the declination from the below listed website and build a table based off the results.&nbsp;</P><P>&nbsp;</P><P><A href="https://www.ngdc.noaa.gov/geomag-web/#declination" target="_blank" rel="nofollow noreferrer noopener">https://www.ngdc.noaa.gov/geomag-web/#declination</A></P> Wed, 26 Apr 2017 12:12:42 GMT https://communities.sas.com/t5/SAS-Programming/Magnetic-declination/m-p/353656#M82562 tobyfarms 2017-04-26T12:12:42Z https://communities.sas.com/t5/SAS-Programming/Magnetic-declination/m-p/353731#M82584 <P>I suggest following the links to WMM model and download that software.
