Returns the union of the geometry. This leaves single geometries untouched, and unions multi geometries.

MultiLineString.dissolve(maxError, proj)Geometry
this: geometryGeometryThe geometry to union.
maxErrorErrorMargin, default: nullThe maximum amount of error tolerated when performing any necessary reprojection.
projProjection, default: nullIf specified, the union will be performed in this projection. Otherwise it will be performed in a spherical coordinate system.
