I want to bring back an old topic, because I did not see that it was
finally solved in a way I can use. I want to be able to load in a geotiff
file from a server (an AWS s3 bucket in particular). I am up for any
method, but I tried to simply pass GeoTiffReader an input stream rather
than a file. I am using Geotools 16 (built up with Maven with Eclipse).
When I create the reader with the following lines:
FileInputStream geotiffFile = new
FileInputStream("location_of_tiff\\tiffFile.tif");
GridCoverage2DReader tiffReader = new GeoTiffReader(geotiffFile);
the class is generated no problem. I can read in the coordinate system, the
size, the number of bands, everything...except the actual data. The
following read line:
rasterData =
tiffReader.read(null);
causes the following (partial) stack.

I have set this up to access a local file on my machine, but I get the
exact same errors if I access the file on an s3 bucket. If, instead of the
FileInputStream, I pass in a File, it works fine with no problems. I feel I
am so close, but my noob status means I have no idea how to fix this!!!
