java - Geotools坐标变换

Question

如何将 EPSG: 54003 中的坐标转换为 EPSG:4326？我使用以下代码

 CoordinateReferenceSystem WORLDCRS = DefaultGeographicCRS.WGS84;
 String wkt = "PROJCS[\"World_Miller_Cylindrical\",GEOGCS[\"GCS_WGS_1984\",DATUM[\"WGS_1984\",SPHEROID[\"WGS_1984\",6378137,298.257223563]],PRIMEM[\"Greenwich\",0],UNIT[\"Degree\",0.017453292519943295]],PROJECTION[\"Miller_Cylindrical\"],PARAMETER[\"False_Easting\",0],PARAMETER[\"False_Northing\",0],PARAMETER[\"Central_Meridian\",0],UNIT[\"Meter\",1],AUTHORITY[\"EPSG\",\"54003\"]]";
    CoordinateReferenceSystem crs;
    MathTransform transform;
    try
    {
        crs = crsFactory.createFromWKT(wkt);
        transform = CRS.findMathTransform(crs, WORLDCRS, true);
        System.out.println(transform.toWKT());
        System.out.println(transform.getClass().getCanonicalName());
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
    try
    {
        transform = CRS.findMathTransform(CRS.decode("EPSG:54003"), WORLDCRS, true);
        System.out.println(transform.toWKT());
        System.out.println(transform.getClass().getCanonicalName());
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
    try
    {
        transform = CRS.findMathTransform(CRS.decode("ESRI:54003"), WORLDCRS, true);
        System.out.println(transform.toWKT());
        System.out.println(transform.getClass().getCanonicalName());
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }`

在pom中，设置依赖

<dependency>
        <groupId>org.geotools</groupId>
        <artifactId>gt-epsg-extension</artifactId>
        <version>11.1</version>
        <scope>compile</scope>
    </dependency>

有 ESRI:54003 CRS 代码吗？

Answer 1

您的 GeoTools 不识别 ESRI:54003 CRS。
您需要使用 EPSG:54003 或其他 CRS。
