    magvar

    This package computes the estimated Magnetic Declination (Decl) (which is sometimes called Magnetic variation) at a specified location based upon the World Magnetic Model 2020-2025. More details can be found at: https://www.ngdc.noaa.gov/geomag/WMM/DoDWMM.shtml

    Getting started

    $ npm install magvar --save

    or

    $ yarn add magvar

    Usage

    Input required is a spot location in geodetic (WGS84) latitude and longitude (positive for northern latitudes and eastern longitudes), geodetic altitude in meters, and the date of interest in years.

    Altitude is optional and should be specified in kilometers above mean sea level - defaults to 0 if not given.

    import MagVar from 'magvar';
    
    const magVar = MagVar.get([latitude], [longitude]);
    
     // or
     
    const magVar = MagVar.get([latitude], [longitude], [height]);

    Take a look at the test file for some examples.
