|
|
|
|
Translated directly from [Tobias Bieniek's implementation in Python](https://github.com/Turbo87/utm).
|
|
|
|
## Usage
|
|
|
|
```js
|
|
var utm = require('utm')
|
|
```
|
|
|
|
### `utm.toLatLon(easting, northing, zoneNum, zoneLetter, northern, strict = true)`
|
|
|
|
Convert from UTM-WGS84 to latitude/longitude coordinates. One and only one of
|
|
`zoneLetter` and `northern` must be specified. `strict` option specifies
|
|
whether easting and northing are checked against their respective ranges.
|
|
|
|
Returns `{ latitude, longitude }`.
|
|
|
|
### `utm.fromLatLon(latitude, longitude[, zoneNum])`
|
|
|
|
Convert from latitude/longitude coordinates to UTM-WGS84. `zoneNum` can be set
|
|
to force a specific zone number.
|
|
|
|
Returns `{ easting, northing, zoneNum, zoneLetter }`.
