Oops. It should be 8; the ewres/nsres values are actually the distances between the centres of the top/bottom rows and left/right columns in the 3x3 window, which are two rows/columns apart. IOW, the 4*ewres should have been 4*(2*ewres) = 8*ewres, ditto for nsres. -- Glynn Clements <[EMAIL PROTECTED]> _______________________________________________ grass-dev mailing list [email protected] http://grass.itc.it/mailman/listinfo/grass-dev
