Hello,
I'm a beginner in using asc grid and geotools library. I'm developing some
processes in java and I would understand the way to know if a generic
coordinate (x,y) is inside the asc file using geotools libraries.
Thanks in advance for any help you will give me.
Sandro

Hi Sandro,
it think you can have a better answer in the GeoTools mailing list.

Anyway, I guess you can get the envelope of the grid and check the
coordinates on it.
File file = new File("/home/xxx/grid.asc");
AbstractGridFormat format = GridFormatFinder.findFormat(file);
reader = format.getReader(file);
GridCoverage2D coverage = reader.read(null);
Envelope2D envelope = coverage.getEnvelope2D(); // the envelope
DirectPosition2D point_to_check = new DirectPosition2D ( x , y ); //
your coordinates
boolean is_inside = envelope.contains(point_to_check); // check if
point is inside the envelope
