Providers and products¶
[1]:
from eodag import EODataAccessGateway
dag = EODataAccessGateway()
Providers available¶
The method available_providers() returns a list of the pre-configured providers.
[2]:
available_providers = dag.available_providers()
available_providers
[2]:
['astraea_eod',
'aws_eos',
'creodias',
'earth_search',
'earth_search_cog',
'mundi',
'onda',
'peps',
'sobloo',
'theia',
'usgs',
'usgs_satapi_aws']
[3]:
print(f"eodag has {len(available_providers)} providers already configured.")
eodag has 12 providers already configured.
It can take a product type as an argument and will return the providers known to eodag that offer this product.
[4]:
dag.available_providers("S2_MSI_L1C")
[4]:
['astraea_eod',
'aws_eos',
'creodias',
'earth_search',
'mundi',
'onda',
'peps',
'sobloo']
Product types available¶
The method list_product_types() returns a dictionary that represents eodag’s internal product type catalog.
[5]:
catalog = dag.list_product_types()
[6]:
catalog[0]

print(f"EODAG has {len(products_id)} product types stored in its internal catalog.")
EODAG has 53 product types stored in its internal catalog.
The method can take a provider name as an argument and will return the product types known to eodag that are offered by this provider.
[9]:
peps_products = dag.list_product_types("peps")
[p["ID"] for p in peps_products]
[9]:
['S1_SAR_GRD', 'S1_SAR_OCN', 'S1_SAR_SLC', 'S2_MSI_L1C', 'S2_MSI_L2A']
Combine these two methods¶
These two methods can be combined to find which product type is the most common in eodag’s catalog among all the providers.
[10]:
availability_per_product = []
for product in products_id:
providers = dag.available_providers(product)
availability_per_product.append((product, len(providers)))
availability_per_product = sorted(availability_per_product, key=lambda x: x[1], reverse=True)
most_common_p_type, nb_providers = availability_per_product[0]
print(f"The most common product type is '{most_common_p_type}' with {nb_providers} providers offering it.")
The most common product type is 'S2_MSI_L1C' with 8 providers offering it.
These can be also used to find out which provider (as configured by eodag) offers the hights number of different product types.
[11]:
availability_per_provider = []
for provider in dag.available_providers():
provider_products_id = [
p["ID"]
for p in dag.list_product_types(provider)
]
availability_per_provider.append(
(provider, len(provider_products_id))
)
availability_per_provider = sorted(availability_per_provider, key=lambda x: x[1], reverse=True)
provider, nb_p_types = availability_per_provider[0]
print(f"The provider with the largest number of product types is '{provider}' with {nb_p_types}.")
The provider with the largest number of product types is 'onda' with 18.
