GeoTools:如何建立一个点? (进口问题) [英] GeoTools: How to build a point? (imports issue)

问题描述

我正在跟踪 GeoTools文档，并发现了这一点:

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);

当我将它放在intellij IDE中时，对于每个类，都有几个建议使用的导入.我需要选择什么导入?

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

(具有相同问题)的替代方法是:

Alternative way (with same issue) is:

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

推荐答案

如有疑问，您可以随时阅读文档，例如

When in doubt you can always read the documentation, for example JTSFactoryFinder returns a com.vividsolutions.jts.geom.GeometryFactory, once you know that the other pieces fall into place as:

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

与此同时，您的 GeometryBuilder 是org.geotools.geometry.GeometryBuilder导致以下导入:

Meanwhile your GeometryBuilder is an org.geotools.geometry.GeometryBuilder which leads to the following imports:

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