Example 2 with LngLatAlt

use of org.geojson.LngLatAlt in project OpenTripPlanner by opentripplanner.

the class PointSet method writeFeature.

/**
 * This writes either a polygon or lat/lon point defining the feature. In
 * the case of polygons, we convert these back to centroids on import, as
 * OTPA depends on the actual point. The polygons are kept for derivative
 * uses (e.g. visualization)
 *
 * @param i
 *            the feature index
 * @param jgen
 *            the Jackson streaming JSON generator to which the geometry
 *            will be written
 * @throws IOException
