Hi WanMil, attached is a small patch which drastically improves BoundaryGrid for tiles that contain mostly sea. I found such a tile in south-america, and the patched version is > 10 times faster. It contais a large part of the pacific, and BoudaryGrid searches the boundary zip file for
5000 different *.bnd files, most of them do not exist in your bounds_20120401.zip , so the code in BoundaryUtil searches through all elements of the zip file to find out that it doesn't exist.
The patch creates a HashSet first with the available files and calls the load routine only for those that exist.
