That's pretty close to what I actually want it for.

The original sites are depth fixes from a swath echosounder.

I want the average value for each cell to create a DTM (median is 
actually better than mean for my application).

I'm then defining training regions over areas of the DTM and calculating 
a variety of statistics for all the cells in each region. (mean, std 
dev, skew, kurt) x (depth, slope, aspect, profile, tangent) and seeing 
if any of these can be used in any way as an indicator of habitat.

Gordon
