1.wkt、geojson转换

import WKT from "terraformer-wkt-parser"
 
 
let wkts = "POLYGON((102.797302689433 36.5936423859273,105.519115206186 29.4789248520356,100.346180647351 19.9699202912212))";
let geojson={
      "type": "Polygon",
      "coordinates": [
        [ [100.0, 0.0], [101.0, 0.0], [101.0, 1.0], [100.0, 1.0], [100.0, 0.0] ],
        [ [100.2, 0.2], [100.8, 0.2], [100.8, 0.8], [100.2, 0.8], [100.2, 0.2] ]
      ]
    }
    
console.log("wkt转geojson",WKT.parse(wkts))
console.log("geojson转wkt",WKT.convert( geojson))

1、三维服务地址转换为二维使用xyz

三维：getMAP?x={TileCol}&y={TileRow}&l={TileMatrix}&styleId=默认&tilesize=256&ratio=1&tilesize=256

二维：Tilematrix={z}&Tilecol={x}&TileRow={y}
