I do not know this (bug)
Good to know.
But i think that nothing change for to make the same satellite map.
If for 1 degree are used 1200 rows and for 5 degree are used 6000 rows , we have to work only with a bigger file.
There is a problem when the map is between 2 tiles , we have to merge 2 files how explained by Brucepos, but is limiting case.(the code for scilab must change)
Another way is to fill the mask with degree of lat and long that include the map ,to avoid this little problem.
(i have not tried) also in this case the rows are different and something in spreadsheet must be changed.

I rethink this , now i have some doubt.
My doubt is , is better to have a tile for 1 degree or a tile for 5 degree for to build a better satellite map?
Now i think a tile for 1 degree,but i am not sure.

I read

The original 5 degree tiles are also sub-tiled for those users requiring easier to manage grids for smaller areas.
The risolution is of 3 arcsec about 90 meters.
Then there is not difference and the risolution is the same, seems to me.
