java中JTS对空间数据Geometry进行坐标系投影转换

代码：

    public Geometry getGeometryForlong(Geometry geometry) {
    
    
        String srcCrsCode = "EPSG:4490";
        String tarCrsCode = "EPSG:4522";

        CoordinateReferenceSystem sourceCRS = null;
        CoordinateReferenceSystem targetCRS = null;

        try{
    
    
            sourceCRS = CRS.decode(srcCrsCode, true);
            targetCRS = CRS.decode(tarCrsCode, true);
        }catch (FactoryException e){
    
    
            System.out.println(e);
        }

        Geometry reprojectGeometry = null;

        try {
    
    
            MathTransform transform = CRS.findMathTransform(sourceCRS, targetCRS);
            reprojectGeometry = JTS.transform(geometry, transform);
        }catch (Exception e){
    
    
            System.out.println(e);
        }

        return reprojectGeometry;
    }

使用：

Geometry regionGeometry = null;
        try {
    
    
            regionGeometry = getGeometryForlong(reader.read(wkt));
        } catch (ParseException e) {
    
    
            e.printStackTrace();
        }

完结！
