gis - GeoTools: How to build a point? (imports issue)

Question

I'm following the GeoTools documentation and found this:

GeometryFactory geometryFactory = JTSFactoryFinder.getGeometryFactory(null);
Coordinate coord = new Coordinate(45, 15);
Point point = geometryFactory.createPoint(coord);

When I put it in intellij IDE, for each class there are several suggested imports to use. What import I need to select?

Alternative way (with same issue) is:

GeometryBuilder builder = new GeometryBuilder(DefaultGeographicCRS.WGS84);
Point point = builder.createPoint(45, 15);

Answer 1

如有疑问，您可以随时阅读文档，例如JTSFactoryFinder返回 a com.vividsolutions.jts.geom.GeometryFactory，一旦您知道其他部分已到位：

import com.vividsolutions.jts.geom.Coordinate;
import com.vividsolutions.jts.geom.GeometryFactory;
import com.vividsolutions.jts.geom.Point;

同时，您的GeometryBuilder是一个org.geotools.geometry.GeometryBuilder导致以下导入的：

import org.geotools.geometry.GeometryBuilder;
import org.geotools.referencing.crs.DefaultGeographicCRS;
import org.opengis.geometry.primitive.Point;
