Add normalizers for OSISAF data #10

Closed akorosov closed 4 years ago

akorosov commented 4 years ago

This is connected to issue in harvesters: https://github.com/nansencenter/django-geo-spaas-harvesting/issues/16

Normalizers for metadata from ingestors (similar to SentinelSAFEMetadataNormalizer) and from Identifier (similar to SentinelOneIdentifierMetadataNormalizer) should be added.

The identifier normalizer should add Parameters: standard_name = sea_ice_area_fraction

It is important to keep in mid extendability to add more sources of data and more parameters from OSISAF.

Raw metadata from MET OSISAF: https://thredds.met.no/thredds/dodsC/osisaf/met.no/ice/amsr2_conc/2020/07/ice_conc_nh_polstere-100_amsr2_202007121200.nc.ddx

After sea ice concentration normalizers for sea ice type and sea ice drift should be added Parameters: sea_ice_x_displacement sea_ice_y_displacement

sea_ice_classification

Everything needed is written in a3466b7 except parameter assignment.

@aanersc , I already wrote these names. See above.

@aperrin66 Please have a look at this new normalizer, If you agree with in general, then I start to write some tests for it. Find it in 7849bf9 please.

Dear @akorosov,

PLease check out the new normalizer of OSISAF from remote sensing point of view in order to deliver meaningfull results in 'get_platform' and 'get_instrument' methods of it. It is necessary to mention this aspect of work.

For all products you can use: pti.get_gcmd_platform('Earth Observation Satellites')

And these instruments:

https://thredds.met.no/thredds/catalog/osisaf/met.no/ice/amsr2_conc/catalog.html pti.get_gcmd_instrument('AMSR2')
