GRIDATB.FOR is available from http://www.es.lancs.ac.uk/hfdg/topmodel.html. As of May 2008, this webpage no longer exists; the closest I could find was http://www.es.lancs.ac.uk/hfdg/freeware/hfdg_freeware_top.htm, and all of the available software on this page seems to VBA/Windows only. ~ Eric Patton. Thanks to Keith Beven. [r.in.gridatb] imports GRIDATB map file.
