feature request: consistent time dimension during data cube export #868

Open mbuchhorn opened 2 weeks ago

mbuchhorn commented 2 weeks ago

current behavior: if a datacube is exported (netCDF or GTiff) then empty time steps (all data for this timestep is nodata over all bands) are removed. e.g. the 10-daily generation of NDVI for a full year --> in the saved netCDF or GeoTiff (split in multiple assets) all timesteps with "nodata" over the full band are missing This can lead to issues in follow-up (openEO external) pipelines where we need all timesteps to run the code correctly even if the data itself is nodata (e.g. HANTS feature extraction, HANTS data compression, break point analysis, ....)

possible solution: add a parameter in the export which would allow to keep even empty data bands exported (filled with specified nodata value)
