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

Feature.dissolve(maxError, proj)Element
this: featureElement

The feature the geometry of which is being unioned.

maxErrorErrorMargin, default: null

The maximum amount of error tolerated when performing any necessary reprojection.

projProjection, default: null

If specified, the union will be performed in this projection. Otherwise it will be performed in a spherical coordinate system.
