Question

我正在尝试在我的一个程序中使用GeoTiff和JAI，但是我遇到了以下错误。

引起：org.opengis.referencing.NoSuchAuthorityCodeException：对于“EngineeringCRS”类型的对象，没有为权限“EPSG”找到代码“EPSG：4326”。

代码如下：

     PixelExtractor ext = new PixelExtractor();
     ext.extract(new File("E:/ll.TIF"), "ESPG:4326", "28/07/2016");

PixelExtractor类是

  for (int j = 0; j < h; j++) {

    double[] latlon = geo(geometry, i, j);
    double lat = latlon[0];
    double lon = latlon[1];

    Double s = 0d;

    String originalBands = "";
    for (int k = 0; k < numBands; k++) {
       double d = raster.getSampleDouble(i, j, k);
      originalBands += d + ",";
      s += d;

    originalBands = originalBands.substring(0, originalBands.length() - 1);
    if (s.compareTo(0d) == 0) {
      continue;
    }
    String geoHash = GeohashUtils.encodeLatLon(lat, lon);
    //here do something with the bands, lat, long, geohash, etc....

  }

 }

 }

  private static double[] geo(GridGeometry2D geometry, int x, int y) throws Exception {

//int zoomlevel = 1;
Envelope2D pixelEnvelop = geometry.gridToWorld(new GridEnvelope2D(x, y, 1, 1));

// pixelEnvelop.getCoordinateReferenceSystem().getName().getCodeSpace();
return new double[]{pixelEnvelop.getCenterY(), pixelEnvelop.getCenterX()};

}

}

在阅读GeoTools espg插件后，我添加了gt-epsg-hsql.jar和包含所有epsg条目的属性文件并将错误更改为

java.lang.NoClassDefFoundError：无法初始化类javax.media.jai.JAI
