@esri/proj-codes
Advanced tools
This module provides a method for looking up information about the Coordinate Reference Systems (CRS) shipped with ArcGIS.
Provide a Well Known ID (WKID) to the lookup()
method and the CRS Name, Well Known Text (WKT) and other metadata will be returned.
npm install @esri/proj-codes
Then require the module, call the lookup
method and pass in your well known id of choice.
const codes = require('@esri/proj-codes')
const crs = codes.lookup(3857)
crs.name
> 'WGS_1984_Web_Mercator_Auxiliary_Sphere'
crs.wkt
> 'PROJCS["WGS_1984_Web_Mercator_Auxiliary_Sphere",GEOGCS["GCS_WGS_1984"...'
crs.description
> 'WGS 1984 Web Mercator Major Auxiliary Sphere'
crs.authority
> 'EPSG'
crs.deprecated
> 'no'
crs.extent
> { "slat": -85.06, "nlat": 85.06, "llon": -180.0, "rlon": 180.0 }
// this works too
codes.lookup(3857).name
> 'WGS_1984_Web_Mercator_Auxiliary_Sphere'
