make aggregation statistics dynamic and not hardcoded for each dataset
Karim Bahgat
committed
reorganize api so time and space aggregation happens hierarchically beneath dataset endpoint
Karim Bahgat
committed
move some funcs to utils.py
Karim Bahgat
committed
add raster with time period aggrgation download endpoint as part of the hierarchy
Karim Bahgat
committed
add dummy tiles endpoint
Karim Bahgat
committed
apply unit conversion earlier so it also affects raster download
Karim Bahgat
committed
switch to proper logging
Karim Bahgat
committed
check and raise dataset id errors more gracefully
Karim Bahgat
committed
validate target period type and skip temporal aggregation if same period type
Karim Bahgat
committed
fix misc dataset metadata
Karim Bahgat
committed
fix period type validation bug, redo json serialization and show correct period format
Karim Bahgat
committed
easier to switch out to different org units, cache builds to latest date by default
Karim Bahgat
committed
switch to more reliable cache background worker, fix dynamic bbox error
Karim Bahgat
committed
speedup unit conversion by doing it on fewer values, stabilize internal code so we always work with an xarray dataset, dask compute after time aggregation to avoid very slow dask graphs later
Karim Bahgat
committed
add cache optimization which builds zarr archive, dataset openers uses zarr file if it exists which is much faster
