Java, convert lat/lon to UTM
提问by Steve Kuo
Does anyone know of a way, in Java, to convert an earth surface position from lat, lon to UTM (say in WGS84)? I'm currently looking at Geotools but unfortunately the solution is not obvious.
有谁知道在 Java 中将地球表面位置从纬度、经度转换为 UTM（例如在 WGS84 中）的方法？我目前正在研究 Geotools，但不幸的是，解决方案并不明显。

I was able to use Geotools 2.4 to get something that works, based on some example code.
根据一些示例代码，我能够使用 Geotools 2.4 来获得一些有用的东西。
double utmZoneCenterLongitude = ... // Center lon of zone, example: zone 10 = -123
int zoneNumber = ... // zone number, example: 10
double latitude, longitude = ... // lat, lon in degrees
MathTransformFactory mtFactory = ReferencingFactoryFinder.getMathTransformFactory(null);
ReferencingFactoryContainer factories = new ReferencingFactoryContainer(null);
GeographicCRS geoCRS = org.geotools.referencing.crs.DefaultGeographicCRS.WGS84;
CartesianCS cartCS = org.geotools.referencing.cs.DefaultCartesianCS.GENERIC_2D;
ParameterValueGroup parameters = mtFactory.getDefaultParameters("Transverse_Mercator");
parameters.parameter("central_meridian").setValue(utmZoneCenterLongitude);
parameters.parameter("latitude_of_origin").setValue(0.0);
parameters.parameter("scale_factor").setValue(0.9996);
parameters.parameter("false_easting").setValue(500000.0);
parameters.parameter("false_northing").setValue(0.0);
Map properties = Collections.singletonMap("name", "WGS 84 / UTM Zone " + zoneNumber);
ProjectedCRS projCRS = factories.createProjectedCRS(properties, geoCRS, null, parameters, cartCS);
MathTransform transform = CRS.findMathTransform(geoCRS, projCRS);
double[] dest = new double[2];
transform.transform(new double[] {longitude, latitude}, 0, dest, 0, 1);
int easting = (int)Math.round(dest[0]);
int northing = (int)Math.round(dest[1]);

No Library, No Nothing. Copy This!
没有图书馆，什么都没有。复制这个！
Using These Two Classes , You can Convert Degree(latitude/longitude) to UTM and Vice Versa!
使用这两个类，您可以将度数（纬度/经度）转换为 UTM，反之亦然！

For my projects I've using the library LatLongLib, from Ahmed Taha. I think that it's very easy to convert coordinates from the UTM system to the Latitude-Longitude system and vice-versa. You just need to play with the classes UTMUtils, UTMPoint and LatLonPoint.
对于我的项目，我使用了来自 Ahmed Taha的图书馆LatLongLib。我认为将坐标从 UTM 系统转换为经纬度系统非常容易，反之亦然。您只需要使用类 UTMUtils、UTMPoint 和 LatLonPoint。
Time ago I also considered choosing Jcoord. It was easy and straight to the point too. However, I needed to use the WGS84 ellipsoid and, at that time, only LatLongLib seemed to have that feature.
前段时间我也考虑过选择Jcoord。这也很简单，直截了当。但是，我需要使用 WGS84 椭球，当时似乎只有 LatLongLib 具有该功能。

You can use this project https://github.com/Berico-Technologies/Geo-Coordinate-Conversion-Java/, adding it to your existing pom.xml using jitpack.
你可以使用这个项目https://github.com/Berico-Technologies/Geo-Coordinate-Conversion-Java/，使用 jitpack 将它添加到你现有的 pom.xml 中。
I've successfully been able to convert UTM coordinates (30N, this is, 30 zone and northern hemisphere) to Latitude and Longitude. See my example below:
我已经成功地将 UTM 坐标（30N，即 30 区和北半球）转换为纬度和经度。请参阅下面的示例：
public void setPunto(Point punto) {
this.punto = punto;
LatLon latlon = UTMCoord.locationFromUTMCoord(30, AVKey.NORTH, punto.getX(), punto.getY());
this.latitud = latlon.getLatitude().degrees;
this.longitud = latlon.getLongitude().degrees;
}
Note that Point class is of com.vividsolutions.jts.geom.Point class type.
请注意， Point 类是 com.vividsolutions.jts.geom.Point 类类型。

The transformation of a coordinate can actually be done in only a few lines of code:
坐标的变换实际上只需几行代码即可完成：
Coordinate coordinate = new Coordinate(x, y);
MathTransform transform = CRS.findMathTransform(CRS.decode("EPSG:4326"), CRS.decode("EPSG:3857"), false);
JTS.transform(coordinate, coordinate, transform);
This will transform a longitude/latitude coordinate (EPSG:4326) into Web Mercator projection (EPSG:3857) coordinate.
这会将经度/纬度坐标 (EPSG:4326) 转换为 Web Mercator 投影 (EPSG:3857) 坐标。
You just need to depend on the following two GeoTools libraries in your build tool (e.g. maven):
