有谁知道在 Java 中将地球表面位置从 lat、lon 转换为 UTM 的方法(比如在 WGS84 中)?我目前正在研究 Geotools,但不幸的是解决方案并不明显。

没有图书馆,什么都没有。复制这个!

使用这两个类,您可以将度数(纬度/经度)转换为 UTM,反之亦然!

private class Deg2UTM
{
    double Easting;
    double Northing;
    int Zone;
    char Letter;
    private  Deg2UTM(double Lat,double Lon)
    {
        Zone= (int) Math.floor(Lon/6+31);

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]);

坐标的变换实际上只需要几行代码就可以完成:

Coordinate coordinate = new Coordinate(x, y);
MathTransform transform = CRS.findMathTransform(CRS.decode("EPSG:4326"), CRS.decode("EPSG:3857"), false);
JTS.transform(coordinate, coordinate, transform); 

这会将经度/纬度坐标 (EPSG:4326) 转换为 Web 墨卡托投影 (EPSG:3857) 坐标。

您只需要在构建工具(例如 maven)中依赖以下两个 GeoTools 库即可:

<repositories>
    <repository>
        <id>osgeo</id>
        <name>Open Source Geospatial Foundation Repository</name>
        <url>http://download.osgeo.org/webdav/geotools/</url>
    </repository>
</repositories>

<dependencies>
    <dependency>
        <groupId>org.geotools</groupId>
        <artifactId>gt-api</artifactId>
        <version>${geotools.version}</version>
    </dependency>
    <dependency>
        <groupId>org.geotools</groupId>
        <artifactId>gt-epsg-hsql</artifactId>
        <version>${geotools.version}</version>
    </dependency>
</dependencies>

此答案基于gis.stackexchange.com上的问题/回复。发布我的回复是因为这里的当前答案似乎很冗长。

对于我的项目,我使用了来自 Ahmed Taha的LatLongLib库。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。

前段时间我也考虑过选择Jcoord。这也很简单直接。但是,我需要使用 WGS84 椭球,当时似乎只有 LatLongLib 具有该功能。

您可以使用此项目https://github.com/Berico-Technologies/Geo-Coordinate-Conversion-Java/,使用 jitpack 将其添加到现有的 pom.xml 中。

我已经成功地将 UTM 坐标(30N,即 30 区域和北半球)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;
}

请注意,Point 类属于 com.vividsolutions.jts.geom.Point 类类型。
