Examples with Geometry org.locationtech.jts.geom.Geometry used on opensource projects

Example 1 with Geometry

use of org.locationtech.jts.geom.Geometry in project h2database by h2database.

the class ValueGeometry method get.

/**
 * Get or create a geometry value for the given geometry.
 *
 * @param s the WKT representation of the geometry
 * @param srid the srid of the object
 * @return the value
 */
public static ValueGeometry get(String s, int srid) {
    try {
        GeometryFactory geometryFactory = new GeometryFactory(new PrecisionModel(), srid);
        Geometry g = new WKTReader(geometryFactory).read(s);
        return get(g);
    } catch (ParseException ex) {
        throw DbException.convert(ex);
    }
}

Example 2 with Geometry

use of org.locationtech.jts.geom.Geometry in project h2database by h2database.

the class ValueGeometry method getGeometry.

/**
 * Get a copy of geometry object. Geometry object is mutable. The returned
 * object is therefore copied before returning.
 *
 * @return a copy of the geometry object
 */
public Geometry getGeometry() {
    Geometry geometry = getGeometryNoCopy();
    Geometry copy = geometry.copy();
    /*
         * Geometry factory is not preserved in WKB format, but SRID is preserved.
         *
         * We use a new factory to read geometries from WKB with default SRID value of
         * 0.
         *
         * Geometry.copy() copies the geometry factory and copied value has SRID form
         * the factory instead of original SRID value. So we need to copy SRID here with
         * non-recommended (but not deprecated) setSRID() method.
         */
    copy.setSRID(geometry.getSRID());
    return copy;
}

Example 3 with Geometry

use of org.locationtech.jts.geom.Geometry in project h2database by h2database.

the class SpatialTreeIndex method getKey.

private SpatialKey getKey(SearchRow row) {
    if (row == null) {
        return null;
    }
    Value v = row.getValue(columnIds[0]);
    if (v == ValueNull.INSTANCE) {
        return null;
    }
    Geometry g = ((ValueGeometry) v.convertTo(Value.GEOMETRY)).getGeometryNoCopy();
    Envelope env = g.getEnvelopeInternal();
    return new SpatialKey(row.getKey(), (float) env.getMinX(), (float) env.getMaxX(), (float) env.getMinY(), (float) env.getMaxY());
}

Example 4 with Geometry

use of org.locationtech.jts.geom.Geometry in project h2database by h2database.

private void testGeometryDataType() {
    GeometryFactory geometryFactory = new GeometryFactory();
    Geometry geometry = geometryFactory.createPoint(new Coordinate(0, 0));
    assertEquals(Value.GEOMETRY, DataType.getTypeFromClass(geometry.getClass()));
}

Example 5 with Geometry

use of org.locationtech.jts.geom.Geometry in project h2database by h2database.

the class TestSpatial method geomFromText.

/**
 * Convert the text to a geometry object.
 *
 * @param text the geometry as a Well Known Text
 * @param srid the projection id
 * @return Geometry object
 */
public static Geometry geomFromText(String text, int srid) throws SQLException {
    WKTReader wktReader = new WKTReader();
    try {
        Geometry geom = wktReader.read(text);
        geom.setSRID(srid);
        return geom;
    } catch (ParseException ex) {
        throw new SQLException(ex);
