Hello all- I have created a kriging map in ArcMap 10, when I try to export to a raster I am givin a default output cell size of 2.36038413599999E-04 which works fine, and creates a raster with cell sizes of 0.000236 meters. However, this is too small for what I am trying to accomplish and when I try to readjust my output cell size to any other value (1,5,10,20, etc.) it produces a bogus map with a cell size of (0,0) and a max and min value of 3.40282e+038 which wont display. I've tried a few different coordinate systems and projections with little results. I would appreciate it if anyone that experienced a similar problem and figured out a solution, or even had some suggestions could shed some light on this situation. Thanks, Jason

The default cell size is calculated as min(width,height)/250.  So, if your default is .000236, setting a cell size of 1 is way too large (the one cell will be many times larger than the entire study area).   You shouldn't use a cell size larger than .000236*250 = .059, and if you want more than one cell, you need something a lot smaller.

I tested using an enormous cell size in ArcGIS 10.1, and I got the same max/min as you (3.40282e+038 is the maximum value of a floating point), but ArcGIS 10.1 displayed the cell size correctly.
