@leewujung This is currently a draft PR because I don't have tests for it yet. However, could you please start reviewing the implementation and help me try out different scenarios to make sure I have it implemented correctly? Thanks!

[leewujung]

@lsetiawan : Could you put in at least a couple test so that it's easier to step through the code? Thanks!

Hi @lsetiawan & @leewujung! what do you think we should do with this PR? There's the resample_to_geometry implementation from Elias now, which I think covers the same general use case? Should we close this one? cheers!
EDIT: there's also this issue still open
