Examples with GeometryPrecisionReducer org.locationtech.jts.precision.GeometryPrecisionReducer used on opensource projects

Example 1 with GeometryPrecisionReducer

use of org.locationtech.jts.precision.GeometryPrecisionReducer in project dotwebstack-framework by dotwebstack.

the class TypeEnforcer method enforcePoint.

private Point enforcePoint(Geometry geometry) {
    GeometryPrecisionReducer precisionReducer = Optional.ofNullable(precisionReducers.get(geometry.getSRID())).orElse(defaultPrecisionReducer);
    var point = (Point) precisionReducer.reduce(geometry.getCentroid());
    point.setSRID(geometry.getSRID());
    return point;
}

Example 2 with GeometryPrecisionReducer

use of org.locationtech.jts.precision.GeometryPrecisionReducer in project teiid by teiid.

the class GeometryUtils method snapToGrid.

public static GeometryType snapToGrid(GeometryType geom, double size) throws FunctionExecutionException {
    if (size == 0) {
        return geom;
    }
    Geometry g1 = getGeometry(geom);
    PrecisionModel precisionModel = new PrecisionModel(1 / size);
    GeometryPrecisionReducer reducer = new GeometryPrecisionReducer(precisionModel);
    reducer.setPointwise(true);
    reducer.setChangePrecisionModel(true);
    Geometry result = reducer.reduce(g1);
    // since the wkb writer doesn't consider precision, we have to first write/read through wkt
    WKTWriter writer = new WKTWriter();
    String val = writer.write(result);
    WKTReader reader = new WKTReader(GEOMETRY_FACTORY);
    try {
        result = reader.read(new StringReader(val));
    } catch (ParseException e) {
        throw new FunctionExecutionException(e);
    }
    return getGeometryType(result, geom.getSrid());
