Spatial Cross Correlation help ly needed

[Mr_Kitsch]

Spatial Cross Correlation help urgently needed!

I am working on Cross Correlation at the moment with varying degrees of success. I have figured out how to do Cross and Auto Correlation but am lost tryng to understand spatial CC. I can't seem to find any helpful resources for what I am working on. I have a formula that doesn't do anything to explain what is going on. The formula is as follows:
ccfg(s) = ∫f(r).g(r+s) dr

If anyone can point me in the right direction or recommend some helpful resources I would very much appreciate it.

Thanks

What seems to be the issue? Temporal and spatial correlations differ only in that the variable changes from t to x.
