Thanks Steve,
That gives me the right calculation. -boice On Dec 22, 2006, at 2:00 PM, Steve Lime wrote:
I believe it's used simply as a multiplier against the previous cellsize. So, if the zoomfactor is 2 then cells in the new extent will be 2 times larger, if -2 then cells will be 2 times smaller.
