within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|

within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and

|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,

|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any

negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability

# geomagnetism
|
||||
[](https://www.npmjs.org/package/geomagnetism)
|
||||
[](https://coveralls.io/r/naturalatlas/geomagnetism)
|
||||
|
||||
`geomagnetism` provides a convenient interface for retrieving the Earth's magnetic declination (variation between magnetic north and true north) at a given location and date. It leverages NOAA's [World Magnetic Model (WMM)](https://www.ngdc.noaa.gov/geomag/WMM/) to compute properties such as declination, inclination, horizontal intensity, and more.
|
||||
|
||||
``` sh
|
||||
$ npm install geomagnetism --save
|
||||
```
|
||||
|
||||
### Usage
|
||||
|
||||
The main entry point is the `model()` function. If you pass it a Date object, it will compute results for that specific date. If you do **not** pass a date, it will default to the current date. Once you have a model, you can query it using the `point()` method, which expects an array representing latitude and longitude. Optionally, you can provide an altitude as a third element in the array.
|
||||
|
||||
- Latitude and longitude are required: `[lat, lon]`
|
||||
- Altitude (optional) can be provided: `[lat, lon, altitude_in_kilometers]`
|
||||
|
||||
**Example: Current Date**
|
||||
|
||||
```js
|
||||
const geomagnetism = require('geomagnetism');
|
||||
|
||||
// If no date is passed, the current date is used
|
||||
const currentModel = geomagnetism.model();
|
||||
const info = currentModel.point([44.53461, -109.05572]); // only lat/lon
|
||||
console.log('Declination (current date):', info.decl, 'degrees');
|
||||
```
|
||||
|
||||
**Example: Specific Date**
|
||||
|
||||
```js
|
||||
const geomagnetism = require('geomagnetism');
|
||||
|
||||
// If a date is passed, that specific date is used
|
||||
const specificDateModel = geomagnetism.model(new Date('2020-10-05'));
|
||||
const info = specificDateModel.point([44.53461, -109.05572]);
|
||||
console.log('Declination on 2020-10-05:', info.decl, 'degrees');
|
||||
```
|
||||
|
||||
**Example: Including Altitude**
|
||||
|
||||
```js
|
||||
const geomagnetism = require('geomagnetism');
|
||||
|
||||
// Provide altitude as the third array item (in kilometers above mean sea level)
|
||||
const model = geomagnetism.model(new Date('2022-01-01'));
|
||||
const infoWithAltitude = model.point([44.53461, -109.05572, 1.5]);
|
||||
console.log('Declination at altitude:', infoWithAltitude.decl, 'degrees');
|
||||
```
|
||||
|
||||
## Handling Out-of-Range Dates
|
||||
|
||||
The `geomagnetism.model()` function determines the best available World Magnetic Model for the date you provide. If the given date falls outside the known range of the WMM data files, by default (`allowOutOfBoundsModel = false`), the function will throw an error indicating that no suitable model is found for the given date.
|
||||
|
||||
If you would prefer that the library "fall back" to the closest available model rather than throwing an error, you can explicitly pass true to allowOutOfBoundsModel option.
|
||||
|
||||
```js
|
||||
geomagnetism.model(date, { allowOutOfBoundsModel: true });
|
||||
```
|
||||
|
||||
- `date`: *(optional)* A JavaScript Date object. Defaults to the current date if not specified.
|
||||
- `allowOutOfBoundsModel`: *(optional)* A boolean. If not specified or false, throws an error if the date is out of range. If true, falls back to the nearest available model.
|
||||
|
||||
**Examples:**
|
||||
|
||||
```js
|
||||
const geomagnetism = require('geomagnetism');
|
||||
|
||||
// Strict behavior (default): If the date is out of range, an error is thrown
|
||||
try {
|
||||
let model = geomagnetism.model(new Date('1900-01-01')); // allowOutOfBoundsModel defaults to false
|
||||
let info = model.point([44.53461, -109.05572]);
|
||||
} catch (err) {
|
||||
console.error('Error (strict mode):', err.message);
|
||||
}
|
||||
|
||||
// Fallback behavior: If the date is out of range, it uses the closest model
|
||||
let fallbackModel = geomagnetism.model(new Date('1900-01-01'), { allowOutOfBoundsModel: true });
|
||||
let fallbackInfo = fallbackModel.point([44.53461, -109.05572]);
|
||||
console.log('Declination using fallback model:', fallbackInfo.decl);
|
||||
```
|
||||
|
||||
## Available Data & Models
|
||||
|
||||
`geomagnetism` ships with multiple versions of the WMM data, each valid for a certain time range. The library automatically picks the correct model based on the date you supply. Older models are included to gracefully handle historical dates when using the fallback behavior.
