API Reference#

This section is autogenerated from in-line code documentation. It is mostly useful as a reference for the various classes, methods, and other objects in the library, but is not intended to function as a starting point for working with pystac_client.

Client#

Client is the base PySTAC-Client that inherits from Catalog. In addition to the PySTAC functionality, Client allows opening of API URLs, understanding of conformance, and support for searching and paging through results.

class pystac_client.Client(id, description, title=None, stac_extensions=None, extra_fields=None, href=None, catalog_type=ABSOLUTE_PUBLISHED, strategy=None, *, modifier=None, **kwargs)[source]#

Bases: Catalog, QueryablesMixin

A Client for interacting with the root of a STAC Catalog or API

Instances of the Client class inherit from pystac.Catalog and provide a convenient way of interacting with STAC Catalogs OR STAC APIs that conform to the STAC API spec. In addition to being a valid STAC Catalog APIs that have a "conformsTo" indicate that it supports additional functionality on top of a normal STAC Catalog, such as searching items (e.g., /search endpoint).

add_conforms_to(name)[source]#

Add "conformsTo" by name.

Parameters:: name – name of ConformanceClasses keys to add.

clear_conforms_to()[source]#

Clear list of "conformsTo" urls

Removes the entire list, so has_conforms_to() will return False after using this method.

conforms_to(conformance_class)[source]#

Checks whether the API conforms to the given standard.

This method only checks against the "conformsTo" property from the API landing page and does not make any additional calls to a /conformance endpoint even if the API provides such an endpoint.

Parameters:: name – name of ConformanceClasses keys to check conformance against.
Returns:: Indicates if the API conforms to the given spec or URI.
Return type:: bool

classmethod from_dict(d, href=None, root=None, migrate=False, preserve_dict=True, modifier=None)[source]#

Parses this STACObject from the passed in dictionary.

Parameters:

d – The dict to parse.
href – Optional href that is the file location of the object being parsed.
root – Optional root catalog for this object. If provided, the root of the returned STACObject will be set to this parameter.
migrate – Use True if this dict represents JSON from an older STAC object, so that migrations are run against it.
preserve_dict – If False, the dict parameter d may be modified during this method call. Otherwise the dict is not mutated. Defaults to True, which results results in a deepcopy of the parameter. Set to False when possible to avoid the performance hit of a deepcopy.

Returns:

The STACObject parsed from this dict.

Return type:

STACObject

classmethod from_file(href, stac_io=None, headers=None, parameters=None, modifier=None, request_modifier=None, timeout=None)[source]#

Open a STAC Catalog/API

Returns:: A Client (PySTAC Catalog) of the root Catalog for this Catalog/API
Return type:: Client

get_all_items()[source]#

Get all items from this catalog and all subcatalogs. Will traverse any subcatalogs recursively, or use the /search endpoint if supported

Returns:

All items that belong to this catalog, and all: catalogs or collections connected to this catalog through child links.

Return type:

Iterator[Item]

get_collection(collection_id)[source]#

Get a single collection from this Catalog/API

Parameters:: collection_id – The Collection ID to get
Returns:: A STAC Collection
Return type:: Union[Collection, CollectionClient]
Raises:: NotFoundError if collection_id does not exist. –

get_collections()[source]#

Get Collections in this Catalog

Gets the collections from the /collections endpoint if supported, otherwise fall back to Catalog behavior of following child links

Returns:: Collections in Catalog/API
Return type:: Iterator[Union[Collection, CollectionClient]]

get_conforms_to()[source]#

List of "conformsTo" URIs

Returns:: List of URIs that the server conforms to
Return type:: List[str]

get_items(*ids, recursive=None)[source]#

Return all items of this catalog.

Parameters:

ids – Zero or more item ids to find.
recursive – unused in pystac-client, but needed for falling back to pystac

Returns:

Iterator of items whose parent is this: catalog.

Return type:

Iterator[Item]

get_merged_queryables(collections)[source]#

Return the set of queryables in common to the specified collections.

Queryables from multiple collections are unioned together, except in the case when the same queryable key has a different definition, in which case that key is dropped.

Output is a dictionary that can be used in jsonshema.validate

Parameters:: List[str] (collections) – The IDs of the collections to inspect.
Returns:: Dictionary containing queryable fields
Return type:: Dict[str, Any]

get_search_link()[source]#

Returns this client’s search link.

Searches for a link with rel=”search” and either a GEOJSON or JSON media type.

Returns:: The search link, or None if there is not one found.
Return type:: Optional[pystac.Link]

has_conforms_to()[source]#: Whether server contains list of "conformsTo" URIs

classmethod open(url, headers=None, parameters=None, ignore_conformance=None, modifier=None, request_modifier=None, stac_io=None, timeout=None)[source]#

Opens a STAC Catalog or API This function will read the root catalog of a STAC Catalog or API

Parameters:

url – The URL of a STAC Catalog.
headers – A dictionary of additional headers to use in all requests made to any part of this Catalog/API.
parameters – Optional dictionary of query string parameters to include in all requests.
ignore_conformance (DEPRECATED) –
Ignore any advertised Conformance Classes in this Catalog/API. This means that functions will skip checking conformance, and may throw an unknown error if that feature is not supported, rather than a NotImplementedError.

Deprecated since version 0.7.0: Conformance can be altered rather than ignored using methods like clear_conforms_to() and add_conforms_to()
modifier –
A callable that modifies the children collection and items returned by this Client. This can be useful for injecting authentication parameters into child assets to access data from non-public sources.

The callable should expect a single argument, which will be one of the following types:
- pystac.Collection
- pystac.Item
- pystac.ItemCollection
- A STAC item-like dict
- A STAC collection-like dict
The callable should mutate the argument in place and return None.

modifier propagates recursively to children of this Client. After getting a child collection with, e.g. Client.get_collection(), the child items of that collection will still be signed with modifier.
request_modifier –
A callable that either modifies a Request instance or returns a new one. This can be useful for injecting Authentication headers and/or signing fully-formed requests (e.g. signing requests using AWS SigV4).

The callable should expect a single argument, which will be an instance of requests.Request.

If the callable returns a requests.Request, that will be used. Alternately, the callable may simply modify the provided request object and return None.
stac_io – A StacApiIO object to use for I/O requests. Generally, leave this to the default. However in cases where customized I/O processing is required, a custom instance can be provided here.
timeout – Optional float or (float, float) tuple following the semantics defined by Requests.

Returns:

A Client instance for this Catalog/API

Return type:

catalog

remove_conforms_to(name)[source]#

Remove "conformsTo" by name.

Parameters:: name – name of ConformanceClasses keys to remove.

search(*, method='POST', max_items=None, limit=None, ids=None, collections=None, bbox=None, intersects=None, datetime=None, query=None, filter=None, filter_lang=None, sortby=None, fields=None)[source]#

Query the /search endpoint using the given parameters.

This method returns an ItemSearch instance. See that class’s documentation for details on how to get the number of matches and iterate over results. The url, stac_io`, and client keywords are supplied by this Client instance.

Warning

This method is only implemented if the API conforms to the STAC API - Item Search spec and contains a link with a "rel" type of "search" in its root catalog. If the API does not meet either of these criteria, this method will raise a NotImplementedError.

Parameters:

method – The HTTP method to use when making a request to the service. This must be either "GET", "POST", or None. If None, this will default to "POST". If a "POST" request receives a 405 status for the response, it will automatically retry with "GET" for all subsequent requests.
max_items – The maximum number of items to return from the search, even if there are more matching results. This client to limit the total number of Items returned from the items(), item_collections(), and items_as_dicts methods(). The client will continue to request pages of items until the number of max items is reached. Setting this to None will allow iteration over a possibly very large number of results.
limit – A recommendation to the service as to the number of items to return per page of results. Defaults to 100.
ids – List of one or more Item ids to filter on.
collections – List of one or more Collection IDs or pystac.Collection instances. Only Items in one of the provided Collections will be searched
bbox – A list, tuple, or iterator representing a bounding box of 2D or 3D coordinates. Results will be filtered to only those intersecting the bounding box.
intersects – A string or dictionary representing a GeoJSON geometry, or an object that implements a __geo_interface__ property, as supported by several libraries including Shapely, ArcPy, PySAL, and geojson. Results filtered to only those intersecting the geometry.
datetime –
Either a single datetime or datetime range used to filter results. You may express a single datetime using a datetime.datetime instance, a RFC 3339-compliant timestamp, or a simple date string (see below). Instances of datetime.datetime may be either timezone aware or unaware. Timezone aware instances will be converted to a UTC timestamp before being passed to the endpoint. Timezone unaware instances are assumed to represent UTC timestamps. You may represent a datetime range using a "/" separated string as described in the spec, or a list, tuple, or iterator of 2 timestamps or datetime instances. For open-ended ranges, use either ".." ('2020-01-01:00:00:00Z/..', ['2020-01-01:00:00:00Z', '..']) or a value of None (['2020-01-01:00:00:00Z', None]).

If using a simple date string, the datetime can be specified in YYYY-mm-dd format, optionally truncating to YYYY-mm or just YYYY. Simple date strings will be expanded to include the entire time period, for example:
- 2017 expands to 2017-01-01T00:00:00Z/2017-12-31T23:59:59Z
- 2017-06 expands to 2017-06-01T00:00:00Z/2017-06-30T23:59:59Z
- 2017-06-10 expands to 2017-06-10T00:00:00Z/2017-06-10T23:59:59Z
If used in a range, the end of the range expands to the end of that day/month/year, for example:
- 2017/2018 expands to 2017-01-01T00:00:00Z/2018-12-31T23:59:59Z
- 2017-06/2017-07 expands to 2017-06-01T00:00:00Z/2017-07-31T23:59:59Z
- 2017-06-10/2017-06-11 expands to 2017-06-10T00:00:00Z/2017-06-11T23:59:59Z
query – List or JSON of query parameters as per the STAC API query extension
filter – JSON of query parameters as per the STAC API filter extension
filter_lang – Language variant used in the filter body. If filter is a dictionary or not provided, defaults to ‘cql2-json’. If filter is a string, defaults to cql2-text.
sortby – A single field or list of fields to sort the response by
fields – A list of fields to include in the response. Note this may result in invalid STAC objects, as they may not have required fields. Use items_as_dicts to avoid object unmarshalling errors.

Returns:

An ItemSearch instance that can be used to iterate through Items.

Return type:

Raises:

NotImplementedError – If the API does not conform to the Item Search spec or does not have a link with a "rel" type of "search".

Item Search#

The ItemSearch class represents a search of a STAC API.

class pystac_client.ItemSearch(url, *, method='POST', max_items=None, stac_io=None, client=None, limit=None, ids=None, collections=None, bbox=None, intersects=None, datetime=None, query=None, filter=None, filter_lang=None, sortby=None, fields=None, modifier=None)[source]#

Represents a deferred query to a STAC search endpoint as described in the STAC API - Item Search spec.

No request is sent to the API until a method is called to iterate through the resulting STAC Items, either ItemSearch.item_collections(), ItemSearch.items(), or ItemSearch.items_as_dicts().

All parameters except url`, method, max_items, and client correspond to query parameters described in the STAC API - Item Search: Query Parameters Table docs. Please refer to those docs for details on how these parameters filter search results.

Parameters:

url – The URL to the search page of the STAC API.
method – The HTTP method to use when making a request to the service. This must be either "GET", "POST", or None. If None, this will default to "POST". If a "POST" request receives a 405 status for the response, it will automatically retry with "GET" for all subsequent requests.
max_items – The maximum number of items to return from the search, even if there are more matching results. This allows the client to limit the total number of Items returned from the items(), item_collections(), and items_as_dicts methods(). The client will continue to request pages of items until the number of max items is reached. By default (max_items=None) all items matching the query will be returned.
stac_io – An instance of StacIO for retrieving results. Normally comes from the Client that returns this ItemSearch client: An instance of a root Client used to set the root on resulting Items.
client – An instance of Client for retrieving results. This is normally populated by the client that returns this ItemSearch instance.
limit – A recommendation to the service as to the number of items to return per page of results. Defaults to 100.
ids – List of one or more Item ids to filter on.
collections – List of one or more Collection IDs or pystac.Collection instances.
bbox – A list, tuple, or iterator representing a bounding box of 2D or 3D coordinates. Results will be filtered to only those intersecting the bounding box.
intersects – A string or dictionary representing a GeoJSON geometry or feature, or an object that implements a __geo_interface__ property, as supported by several libraries including Shapely, ArcPy, PySAL, and geojson. Results filtered to only those intersecting the geometry.
datetime –
Either a single datetime or datetime range used to filter results. You may express a single datetime using a datetime.datetime instance, a RFC 3339-compliant timestamp, or a simple date string (see below). Instances of datetime.datetime may be either timezone aware or unaware. Timezone aware instances will be converted to a UTC timestamp before being passed to the endpoint. Timezone unaware instances are assumed to represent UTC timestamps. You may represent a datetime range using a "/" separated string as described in the spec, or a list, tuple, or iterator of 2 timestamps or datetime instances. For open-ended ranges, use either ".." ('2020-01-01:00:00:00Z/..', ['2020-01-01:00:00:00Z', '..']) or a value of None (['2020-01-01:00:00:00Z', None]).

If using a simple date string, the datetime can be specified in YYYY-mm-dd format, optionally truncating to YYYY-mm or just YYYY. Simple date strings will be expanded to include the entire time period, for example:
- 2017 expands to 2017-01-01T00:00:00Z/2017-12-31T23:59:59Z

sortby – A single field or list of fields to sort the response by
fields – A list of fields to include in the response. Note this may result in invalid STAC objects, as they may not have required fields. Use items_as_dicts to avoid object unmarshalling errors.
modifier –
A callable that modifies the children collection and items returned by this Client. This can be useful for injecting authentication parameters into child assets to access data from non-public sources.

The callable should expect a single argument, which will be one of the following types:
