I have written a piece of Java code that accesses a large Geotiff. My code utilizes the GeoTiffReader method. When I run the code locally I simply pass GeoTiffReader the file name, and everything works fine. However, I am ultimately trying to have the code read the raster from an AWS S3 bucket. What I have tried to do is set up a local FileInputStream, and pass that to GeoTiffReader. It seems to work fine, up to a point. It correctly reads in the number of bands, the CRS, everything…except the actual data! When I try to read in that, it crashes. The following two lines are where it all goes south:
This works:
GridCoverage2DReader reader = new GeoTiffReader(file); //One result from the grid read
this.grid = reader.read(null);
This does not:
GridCoverage2DReader reader = new GeoTiffReader(fileInputStream); //One result from the grid read
this.grid = reader.read(null);
When it is sent a FileInputStream, the read method gets as far as the AbstractGridCoverage2DReader class. Inside of the getRescaledRasterToModel method it crashes on the first line with
final int ssWidth = coverageRaster.getWidth();
I get this same error if I host the file locally or on the AWS s3 bucket. As I said, it opens the GeoTiff just fine, and accesses all of the positional data. It just fails with the final read of the actual data. Any help is HUGELY appreciated!
The key imports are as follows:
import org.geotools.coverage.grid.io.GridCoverage2DReader;
import org.geotools.gce.geotiff.GeoTiffReader;
import org.geotools.coverage.grid.*;
import org.opengis.coverage.grid.*;

If I run with the Netbeans standard debugging setup, I get the following stack trace:
