Example 1 with JtsLocationConverter

use of org.openstreetmap.atlas.geography.converters.jts.JtsLocationConverter in project atlas by osmlab.

the class MultiPolygon method isOSMValid.

/**
 * @return True if this {@link MultiPolygon} is valid according to the OSM specification. OSM
 *         allows some inners of the MultiPolygon to touch on more than a single point, to allow
 *         for one inner to be split in multiple parts tagged differently. Example: a forest
 *         with an inner, that is one side a meadow, and on the other side some marshland.
