2.arcgis geometry json与geojson互转
Convert ArcGIS JSON geometries to GeoJSON geometries and vice versa.
npm install @terraformer/arcgis
(1)arcgis geometry json转换成geojson格式
import { arcgisToGeoJSON } from "@terraformer/arcgis" arcgisToGeoJSON({ "x":-122.6764, "y":45.5165, "spatialReference": { "wkid": 4326 } }); >> { "type": "Point", "coordinates": [ -122.6764, 45.5165 ] }
(2)geojson转换成arcgis geometry json
import { geojsonToArcGIS } from "@terraformer/arcgis" geojsonToArcGIS({ "type": "Point", "coordinates": [45.5165, -122.6764] }) >> { "x":-122.6764, "y":45.5165, "spatialReference": { "wkid": 4326 } }
3.wkt与geojson格式互转
Tools to convert WKT geometries to GeoJSON geometries and vice versa.
(1)wkt转成geojson
import { wktToGeoJSON } from "@terraformer/wkt" wktToGeoJSON("POINT (-122.6764 45.5165)"); >> { "type": "Point", "coordinates": [ -122.6764, 45.5165 ] }
(2)geojson转成wkt
import { geojsonToWKT } from "@terraformer/wkt" const geojsonPoint = { "type": "Point", "coordinates": [-122.6764, 45.5165] } geojsonToWKT(geojsonPoint) >> "POINT (-122.6764 45.5165)"
