Geo-Web-Project / js-geo-web-coordinate

A small JS library to handle Geo Web Coordinates

js-geo-web-coordinate

A Javascript implementation of converting GeoWebCoordinate to GPS coordinates. See the spec.

Install

npm install js-geo-web-coordinate

Usage

Convert GPS -> Geo Web Coordinate

const GeoWebCoordinate = require("js-geo-web-coordinate");

let lon = 110.0;
let lat = 38.0;

let gwCoord = GeoWebCoordinate.from_gps(lon, lat);

Convert Geo Web Coordinate -> GPS Bounding Box

const GeoWebCoordinate = require("js-geo-web-coordinate");

let gpsCoords = GeoWebCoordinate.to_gps(gwCoord);

Note: Calculating bounding boxes will round results to the nearest 10 digits. This may result in small rounding errors when calculating bounding boxes of a coordinate.
