在JavaScript /谷歌地图磁偏角 [英] Magnetic declination in JavaScript / Google Maps

问题描述

在Google Map Javascript应用程序的环境中，获得特定Lat / Lon磁偏角的最佳方式是什么？

1. 在JS中似乎没有简单的算法，或者我错了？


2. 有没有Google Maps API可以确定这一点的方法，我还没有找到...


3. 可以使用的Web服务..我发现 WebSites 提供此功能，但不支持API。 另请参阅

他们有这个碎片。对于谷歌地图与源代码混搭，请参阅： -

In the context of a Google Map Javascript application, what is the best way to get the magnetic declination for a certain Lat/Lon?

1. There seems to be no "easy" algorithm for that in JS, or am I wrong?
2. Is there a way with Google Maps API to determine this, I haven't found one...
3. A Web Service which can be used .. I have found WebSites offering this, but no API.
4. Also see here, there they use a JavaScript class for this (see comment)

解决方案

They have shard this. For Google maps mashup with source see:-
