Java，将 lat/lon 转换为 UTM [已关闭]
2022-09-01 12:38:43
有谁知道在Java中将地球表面位置从lat，lon转换为UTM的方法（例如在WGS84中）？我目前正在研究Geotools，但不幸的是，解决方案并不明显。
答案 1
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（纬度/经度）转换为UTM，反之亦然！

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);
