GIS坐标转换工具
该工具引用 gcoord https://www.npmjs.com/package/gcoord 和 proj4库, 实现坐标任意转换。
使用方法: npm安装:npm install geotransform --save
import GeoTransform from "geotransform";
let gt = new GeoTransform();
let coords = [113.620605, 34.748383];
let transCoords = gt.transform("WGS84", "EPSG:4547", coords);
let transCoords1 = gt.transform("GCJ02", "EPSG:4547", coords);
let transCoords2 = gt.transform("GCJ02", "WGS84", coords);
let transCoords3 = gt.transform("EPSG:4326", "EPSG:4547", coords);
let transCoords4 = gt.transform("EPSG:4326", "GCJ02", coords);
/**
- 坐标转换方法 gt.transform(fromSR, toSR, coords);
- @param {*} fromSR 转换前的坐标系
- @param {*} toSR 转换后的坐标系
- @param {*} coordinates 坐标值[x, y] */
支持EPSG编码坐标系转换,与非EPSG互转
非EPSG支持以下互转
"GCJ02" -> "高德坐标"
"BD09" -> "百度坐标"
"BD09MC" -> "百度墨卡托坐标"
"EPSG3857" -> "墨卡托坐标"
"WGS84" -> "84地理坐标"
