I’m aware of the large area utilities, but AFAIK there isn’t a utility for combining the data from a gridded request back into a single array (though I would imagine this is often the desired behavior for a large-area request). I wanted to check whether someone has written a nice general tool for splitting and merging large area requests, gridding as much as is necessary.

I currently split large requests into a 3x3 grid, accumulate the data in a list, and assign the relevant sections to a numpy array. But there are a few things inconvenient about it:

• I’m manually defining the grid order to loop through (though I could probably do it programmatically, sorting by lat and then lon)


• My code doesn’t (currently) generalize to NxN grid, which would be nice (some areas I want are far too large even when split into 9 parts).


• The three returned segments that are supposed to share an edge don’t have the same size (e.g., 2/3 have a width that’s 1 pixel thinner than the full-size image). Not sure how to get around this…
