ee.Geometry.LinearRing.dissolve

Returns the union of the geometry. This leaves single geometries untouched, and unions multi geometries.
Usage Returns
LinearRing. dissolve ( maxError , proj ) Geometry
Argument Type Details
this: geometry
Geometry The geometry to union.
maxError
ErrorMargin, default: null The maximum amount of error tolerated when performing any necessary reprojection.
proj
Projection, default: null If specified, the union will be performed in this projection. Otherwise it will be performed in a spherical coordinate system.
