我编写了一段访问大型Geotiff的Java代码。我的代码使用GeoTiffReader方法。当我在本地运行代码时，我只需传递GeoTiffReader文件名，一切正常。但是，我最终试图让代码从AWS S3存储桶中读取栅格。 我试图做的是设置一个本地FileInputStream，并将其传递给GeoTiffReader。它似乎工作正常，达到一定程度。它正确地读取了波段数，CRS，一切......除了实际数据！当我尝试阅读时，它会崩溃。以下两行是向南走的地方：
这有效：
GridCoverage2DReader reader = new GeoTiffReader(file); //One result from the grid read
this.grid = reader.read(null);
这不是：
GridCoverage2DReader reader = new GeoTiffReader(fileInputStream); //One result from the grid read
this.grid = reader.read(null);
当发送FileInputStream时，read方法会获得AbstractGridCoverage2DReader类。在getRescaledRasterToModel方法内部，它在
的第一行崩溃final int ssWidth = coverageRaster.getWidth();
如果我在本地或在AWS s3存储桶上托管文件，我会收到同样的错误。正如我所说，它打开GeoTiff就好了，并访问所有位置数据。它只是最终读取实际数据失败了。任何帮助都非常感谢！
密钥导入如下：
import org.geotools.coverage.grid.io.GridCoverage2DReader;
import org.geotools.gce.geotiff.GeoTiffReader;
import org.geotools.coverage.grid.*;
import org.opengis.coverage.grid.*;

如果我使用Netbeans标准调试设置运行，我会得到以下堆栈跟踪：
