Hi John,

My main point was when averaging do you use mean or median. (For the actual project I don't use calcimage, as i'm dealing with subareas in a map that are non orthogonal)

Thanks

Ben

Hi Ben,
We're just using mean averaging in our Surfer strip scripts, but they could be easily modified for median averaging.  Very fancy that you are dealing with non orthogonal directions with your strip averaging!    Cool!

The only stupid question is the one not asked!

Here are the results from the cartoon example show above, you can see the difference between mean and median. (Although I realised that for R extract function for non-parallel line there is a slight distortion of distance scale, which must be corrected)
