catalogs vs collections in ep 5

[rbavery]

the new earth search endpoint (incorrectly?) says there are 7 catalogs, when I think they mean 7 collections. So we should refer to collections throughout, and the earth search v1 STAC API as hosting a single catalog. is that right @vincentsarago?

Yep, I think stac-browser is messing with name catalog/collections

The stac-api has 7 collections:

curl https://earth-search.aws.element84.com/v1/collections | jq '.collections | length'  
7
