Transform coordinates between projections (coordinate systems).

npm install --save coordinates-transformer

import transform from 'coordinates-transformer'

transform([12345.36, 6730006.31], 'EPSG:25833', 'EPSG:4258')
// Returns: [ 6.129140025806947, 60.41006820280935 ]

(coordinates: [number, number], fromProjection: EpsgCode, toProjection?: EpsgCode) => [number, number]

All coordinates are on the format [longitude, latitude] format (or [easting, northing]).

If the third parameter toProjection is omitted, EPSG:4258 is used.

An EPSG code represents a projection (coordinate system). Read about EPSG on https://epsg.io/ or https://register.geonorge.no/epsg-koder (Norwegian site).

Available EPSG codes:

• EPSG:4258 (lat/long)
• EPSG:25831 (UTM 31)
• EPSG:25832 (UTM 32)
• EPSG:25833 (UTM 33)
