java - 从 EPSG :4326 to EPSG:31467 in Java/GWT server side 转换坐标

Question

我一直在使用来自 https://ariasprado.name/2012/08/13/quick-and-dirty-coordinate-transforming-using-geotools.html#comment-792 的以下代码在我的 GWT 服务器端，并完全按照说明附加了所有必需的 jar。附加错误日志。任何帮助将不胜感激。提前致谢

    import org.geotools.geometry.DirectPosition2D;

    import org.geotools.referencing.CRS;

    import org.opengis.referencing.crs.CoordinateReferenceSystem;

    import org.opengis.referencing.operation.MathTransform;

    ...

    CoordinateReferenceSystem sourceCrs = CRS.decode("EPSG:25829");
    CoordinateReferenceSystem targetCrs = CRS.decode("EPSG:4326");

    double x = (double) 636497.59434;
    double y = (double) 4778964.017375;

    boolean lenient = true;
    MathTransform mathTransform 
        = CRS.findMathTransform(sourceCrs, targetCrs, lenient);

    DirectPosition2D srcDirectPosition2D 
        = new DirectPosition2D(sourceCrs, x, y);
    DirectPosition2D destDirectPosition2D 
        = new DirectPosition2D();
    mathTransform.transform(srcDirectPostion2D, destDirectPosition2D);

    double transX = destDirectPosition2D.x;
    double transY = destDirectPosition2D.y;

Answer 1

从代码来看，它实际上看起来还不错。 (我将在下面添加一个 CRSCoordinateTransformer 类，它绝对“适合我”。)

所以我假设是类路径问题。如果您拥有所有必需的库？我的猜测是您拥有 API 库但没有实际的实现。 GeoTools 提供坐标更改器(mutator)的不同实现。例如 gt2-epsg-hsql，它从嵌入式 HSQLDB 数据库加载转换。您是否包含其中一种 JAR，或者您是否只有 gt2-referencing？

下面是 mvn dependency:tree 的一个片段，来自一个已知转换有效的项目:

[INFO] +- org.geotools:gt2-epsg-hsql:jar:2.4.5:compile
[INFO] |  +- org.geotools:gt2-referencing:jar:2.4.5:compile
[INFO] |  |  +- java3d:vecmath:jar:1.3.1:compile
[INFO] |  |  \- org.geotools:gt2-metadata:jar:2.4.5:compile
[INFO] |  |     +- org.opengis:geoapi-nogenerics:jar:2.1.0:compile
[INFO] |  |     \- javax.units:jsr108:jar:0.01:compile
[INFO] |  \- hsqldb:hsqldb:jar:1.8.0.7:compile

该版本可能已经很旧了，但这应该可以让您了解需要哪些库。如果您使用 Maven，请运行 mvn dependency:tree 并检查(和/或发布)输出。
