Method Overview

Method Details

normalizeCentralMeridian(geometries, geometryService){Promise<Geometry[]>}

Normalizes geometries that intersect the central meridian or fall outside the world extent so they stay within the coordinate system of the view. Only supported for Web Mercator and WGS84 spatial references.

Parameters:

geometries Geometry[] An array of geometries to normalize.

geometryService GeometryService optional A geometry service used to perform the normalization. If this value is null then the default geometry service in esriConfig.geometryServiceUrl is used.

Returns:

Type	Description
Promise<Geometry[]>	Resolves to an array of the normalized geometries.

Example:

// create a non-normalized line that crosses the dateline
const polyline = new Polyline({
  paths: [
    [170, 52.68],
    [190, 49.5]
  ]
});

normalizeUtils.normalizeCentralMeridian([polyline])
  .then(function(polylines){
    // returns a line representing the same geometry, but
    // now is normalized between -180 and 180 on the x-coordinate.
    // but represents the same feature
    const graphic = new Graphic({
      geometry: polylines[0],
      symbol: { type: "simple-line" }
    });
