点与线

在这里插入图片描述

    /*** 点与线, 点必须是多点，且有一个点在线上,因为是交叉点，在线上* [T*T******]*/public void test00() {coordinate1 = new Coordinate[] {new Coordinate(4, 3), new Coordinate(13, 3)};LineString lineString = geometryFactory.createLineString(coordinate1);coordinate2 = new Coordinate[] {new Coordinate(8, 6), new Coordinate(8, 1), new Coordinate(9, 3)};MultiPoint multiPoint = geometryFactory.createMultiPointFromCoords(coordinate2);LOGGER.info("lineString1 - point1 九交模型值：{}", lineString.relate(multiPoint).toString());LOGGER.info("point1 - lineString1 跨越：{}", lineString.crosses(multiPoint));LOGGER.info("lineString1: {}, point1: {}", WKT_WRITER.write(lineString), WKT_WRITER.write(multiPoint));}

点与面

在这里插入图片描述

    /*** 点与面* [T*T******]*/public void test01() {coordinate1 = new Coordinate[] {new Coordinate(8, 6), new Coordinate(8, 1), new Coordinate(9, 3)};MultiPoint multiPoint = geometryFactory.createMultiPointFromCoords(coordinate1);coordinate2 = new Coordinate[] {new Coordinate(2, 5), new Coordinate(2, 2), new Coordinate(12, 2), new Coordinate(12, 5), new Coordinate(2, 5)};Polygon polygon = geometryFactory.createPolygon(coordinate2);LOGGER.info("multiPoint1 - polygon 九交模型值：{}", multiPoint.relate(polygon).toString());LOGGER.info("multiPoint1 - polygon 跨越：{}", multiPoint.crosses(polygon));LOGGER.info("multiPoint1: {}, polygon: {}", WKT_WRITER.write(multiPoint), WKT_WRITER.write(polygon));}

线与面

在这里插入图片描述
