Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@datafire/amentum_space_global_magnet

Client library for Global Magnet API - calculate main components of the geomagnetic field at or near Earth's surface

Installation and Usage

npm install --save @datafire/amentum_space_global_magnet
let amentum_space_global_magnet = require('@datafire/amentum_space_global_magnet').create();

.then(data => {
  console.log(data);
});

Description

The World Magnetic Model calculates the intensity and direction of the Earth's magnetic field on a specific date-time, geodetic altitude, latitude, and longitude. It is relied upon throughout the world for navigation, mineral exploration, atmospheric and space science, and is installed on billions of devices. A comprehensive description of the World Magnetic Model, including its limitations, can be found here. We provide a RESTful API to access the out-of-cycle World Magnetic Model (WMM2015v2) valid for years 2015.0 - 2020.0 and WMM2020 valid for years 2020.0 - 2025.0 The Global Magnet API wraps the original WMM code which is available here. Amentum Pty Ltd is not responsible nor liable for any loss or damage of any sort incurred as the result of the use of the API. The API is rate limited to 10,000 calls per month for non commercial use. Contact [email protected] to discuss paid plans and commercial use. Copyright Amentum Pty Ltd 2020.

Actions

app.api_wmm.endpoints.WMM.magnetic_field

Declination (degrees) - angle in the horizontal plane between magnetic north and true north. Declination is positive when magnetic north is east of true north. Inclination, or dip (degrees) - angle made between the horizontal plane and the magnetic field vector at some position. Positive inclination corresponds to a downward pointing magnetic field. Total Intensity (nano Teslas) Grid Variation (deg) referenced to grid north. Grid north reference to 0 deg meridian of a polar stereographic projection. Only defined for latitudes greater than 55 degrees and less than -55 degrees (arctic and antarctic).
