  A few years ago, I wrote a small C program to translate the ESRI exported
.grd file format to something usable. I'll send you the source and
executable (it translated to linux perfectly, of course <g>) this weekend.
I'm on my way out the door for a business trip and I won't be back until
Friday evening.

  The only guess was where ESRI puts the cell location: center, southwest
corner, or some place else. IMO, for most natural system data any error this
induces doesn't matter at all.
