26 maj 2024 · Our calculator will help you find the magnetic declination for your specific location and date. A positive declination (+D) means that your compass will point east of north. A negative declination (-D) means that your compass will point west of north.
2 lip 2022 · Use the tool below to compute values for the geomagnetic field and secular variation for a given set of coordinates and date. This calculator uses the World Magnetic Model as released in Dec 2019.

MagDec is a graphical front end for the NCEI online Magnetic Field Calculators that eliminates the need to input geodetic coordinates and displays the calculated magnetic declination and secular variation in a placemark balloon.
25 maj 2024 · Calculate the geomagnetic declination at the Space Needle in Seattle, WA: >>> from pygeomag import GeoMag >>> geo_mag = GeoMag () >>> result = geo_mag . calculate ( glat = 47.6205 , glon =- 122.3493 , alt = 0 , time = 2023.75 ) >>> print ( result . d ) 15.25942260585284
Declination results are typically accurate to 30 minutes of arc, but environmental factors can cause magnetic field disturbances. The calculator provides an easy way for you to get results in HTML, XML, CSV, or JSON programmatically (API). Registration is required to access this service.
For this calculator you enter the co-ordinates (latitude and longitude) of your site in degrees, minutes and seconds and it will instantly convert them to eastings and northings expressed in TM grid references. They are then in the form required by GetDec. The programme will then tell you not only the sun’s “apparent declination” but also the
