Converting Cokriging result to Raster dilemma

[SethAdams]

Hi all,

I have a bizarre issue occurring when I try and convert my resulting image into a raster for analysis.

The conversion is successfull, but the max and min values are terribly off.

In my Cokriging image, the min is zero and the max is around 420.  When the image is converted to a raster with a cell size of one, the min is slightly above one and the max is around 130.

Does anyone have any idea why it is ommitting a large portion of the values?

Thank you for any help,

Seth

Thank you so much for the help Steve!

So in order to obtain the true values in the grid conversion, it would appear that I would need to select a cell size of less than one, is this correct?

Processing time is not an issue, but I would rather the program not crash when performing the large amount of calculations needed.

Lets say that you output to a raster with a cell size of 10 meters and it produces a raster with 5 columns and 5 rows. Geostatistical Analyst is making 25 predictions, each at the center of the output 10 meter cell. Now you change the cellsize to 5 m, now you have 100 predictions, and so on.
