Dear all,
I am trying to migrate my project from gt 2.5 to 2.6, and I ran into a
problem with geotiffreader.
Neither
reader = new GeoTiffReader(file, new
Hints(Hints.FORCE_LONGITUDE_FIRST_AXIS_ORDER, Boolean.TRUE));
nor
reader = new GeoTiffReader(file);
works, with the following stack trace:
Exception in thread "main" java.lang.NoSuchMethodError:

I also used to do:
reader = new GeoTiffReader(file);
double rasterNodata = reader.getMetadata().getNoData();
this method is now gone, and there is a hasNoData() method. That's fine,
but how can I get the actual value back?
This is the GDALINFO output from the tif I am reading(a SRTM DEM in
geoTiff):
