Example 6 with SpatialDistanceFilter

use of ddf.catalog.impl.filter.SpatialDistanceFilter in project ddf by codice.

the class OpenSearchFilterVisitor method visit.

     * DWithin filter maps to a Point/Radius distance Spatial search criteria.

        // get geometry expression as literal and then evaluate it to get
        // the geometry.

Example 7 with SpatialDistanceFilter

use of ddf.catalog.impl.filter.SpatialDistanceFilter in project ddf by codice.

    Geometry geometry = distanceFilter.getGeometry();
