Data indexing from DEAfrica STAC is not working

Question

I am trying to index some Sentinel-1 data from the DEAfric STAC catalogue and have added the product using the following command

docker-compose exec jupyter datacube product add https://raw.githubusercontent.com/digitalearthafrica/config/master/products/esa_s1_rtc.odc-product.yaml

However, when I try to index data using the command below:

docker-compose exec jupyter bash -c "stac-to-dc --bbox='26,-10,25,-11' --collections='s1_rtc' --datetime='2020-01-01/2021-9-20'"

I get the following error:

Traceback (most recent call last): File "/usr/local/lib/python3.8/dist-packages/pystac_client/stac_api_io.py", line 109, in request raise APIError(resp.text) pystac_client.exceptions.APIError: index_not_found_exception

During handling of the above exception, another exception occurred:

It's probably because the default STAC api, the stac-to-dc tool pointing to is from https://earth-search.aws.element84.com/v0/ and it doesn't have a STAC collection called 's1_rtc'.

If you change your STAC url to the one from Digital Earth Africa, they seem to have a collection called 's1_rtc'. Hopefully this would add new datasets to your datacube index.

stac-to-dc --bbox='26,-10,25,-11' --collections='s1_rtc' --datetime='2020-01-01/2021-9-20' --catalog-href='https://explorer.digitalearth.africa/stac'
