@rowannicholls a quick note to say that the tests appear to be failing because the runner has run out of disk space (https://github.com/kraemer-lab/DART-Pipeline/actions/runs/9977049468?pr=89). accordings to the specs, standard runners have 14Gb of storage available. you may need to tidy-up the files, or test collation and aggregation for one dataset at a time.

@jsbrittain thanks for catching that, I'll take a look

@jsbrittain the culprit seems to have been a population density map from Meta's Data for Good which was 13.3 GB. Have fixed.
