ee.Geometry.LinearRing

  • ee.Geometry.LinearRing constructs a LinearRing geometry with automatic closure if the last point doesn't match the first.

  • For convenience with geodesic EPSG:4326 LinearRings, number varargs can be used for coordinates.

  • The function accepts coordinate lists in various formats, including GeoJSON and lists of numbers or ee.Geometry objects.

  • Optional arguments allow specifying projection, geodesic state, and maximum error for reprojection.

Constructs an ee.Geometry describing a LinearRing. If the last point is not equal to the first, a duplicate of the first point will be added at the end.

For convenience, varargs may be used when all arguments are numbers. This allows creating geodesic EPSG:4326 LinearRings given an even number of arguments, e.g. ee.Geometry.LinearRing(aLng, aLat, bLng, bLat, ..., aLng, aLat).

UsageReturns
ee.Geometry.LinearRing(coords, proj, geodesic, maxError)Geometry.LinearRing
ArgumentTypeDetails
coordsList<Geometry>|List<List<Number>>|List<Number>A list of points in the ring. May be a list of coordinates in the GeoJSON 'LinearRing' format, a list of at least three ee.Geometry objects describing a point, or a list of at least six numbers defining the [x,y] coordinates of at least three points.
projProjection, optionalThe projection of this geometry. If unspecified, the default is the projection of the input ee.Geometry, or EPSG:4326 if there are no ee.Geometry inputs.
geodesicBoolean, optionalIf false, edges are straight in the projection. If true, edges are curved to follow the shortest path on the surface of the Earth. The default is the geodesic state of the inputs, or true if the inputs are numbers.
maxErrorErrorMargin, optionalMax error when input geometry must be reprojected to an explicitly requested result projection or geodesic state.
