How can I extract all cells from a fishnet into their own cells?

Question

I want to run the band collection statistics tool between 2 different rasters to determine their correlation. I can run this on the entire region and get 1 value, but I would like to create several smaller areas within the region to get several r values for the entire region.

So far I have created a fishnet over the region, with cells that are 1000m x 1000m. I want to determine what the correlation between 2 rasters is within each cell of my fishnet, thus resulting in several r values over the entire region.

I don't know how to run the band collection statistics tool within each of cell of my fishnet layer, so I thought I would extract each cell as a new layer...my only problem is that I have ~4000 cells, so this would be very time consuming.

I have tried to create a model in model builder to select each cell and then extract the selection. I used the "iterate feature selection" iterator to select each different cell, but then I don't know what tool I should use to extract/export each cell selection as a new layer. I know how to export selected data (by right clicking on the layer I want to export from), but I don't know how to get this tool into my model.

I ultimately would like to run band collection statistics on each cell (between 2 rasters) and apply the r value to the cell, allowing me to display areas of high and low correlation with a stretched colour scheme.

If anyone has any ideas on how I can run this a little more efficiently, please let me know.

I found a better answer...batch processing! What a life saver.

No need for iterations or extract by mask. Extract by mask seems to work sporadically (as I found by trying to use it, and then also seeing several other people have the same problem in the forums).

So this is what I did:

To extract all cells from my fishnet, I used the select layer by attribute tool. Arc10 freezes all the the time...so I did it manually. I should have been able to make model and set the expression and output layer as parameters, then run in batch processing...but arc10 seems extremely crash happy when I try to use a model or batch processing.

So it does work! My next question is, how can I get the final output to be different for each iteration automatically? I know how to set the output as a parameter, but it would be too time consuming for me to enter in the output name every single time it runs...and that would defeat the purpose of an iterator.

Thanks, Darren. I just built the model and it looks like it is going to work. I will let it run and let you know the results when I get them!
