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

Example 6 with MultiLineString

use of org.locationtech.jts.geom.MultiLineString in project arctic-sea by 52North.

the class GeoJSONEncoder method encode.

protected ObjectNode encode(MultiLineString geometry, int parentSrid) {
    Preconditions.checkNotNull(geometry);
    ObjectNode json = jsonFactory.objectNode();
    ArrayNode list = json.put(JSONConstants.TYPE, JSONConstants.MULTI_LINE_STRING).putArray(JSONConstants.COORDINATES);
    for (int i = 0; i < geometry.getNumGeometries(); ++i) {
        list.add(encodeCoordinates((LineString) geometry.getGeometryN(i)));
    }
    encodeCRS(json, geometry, parentSrid);
    return json;
}

Example 7 with MultiLineString

use of org.locationtech.jts.geom.MultiLineString in project presto by prestodb.

the class GeoFunctions method stIsClosed.

    }
    // This would be handled in validateType, but for completeness.
    throw new PrestoException(INVALID_FUNCTION_ARGUMENT, format("Invalid type for isClosed: %s", geometry.getGeometryType()));
