¶
Get the STAC client. It wraps the pystac.Client.open() method. See https://pystac-client.readthedocs.io/en/stable/api.html#pystac_client.Client.open
Parameters:
Name | Type | Description | Default |
---|---|---|---|
url |
str |
The URL of a STAC Catalog. |
required |
headers |
dict |
A dictionary of additional headers to use in all requests made to any part of this Catalog/API. Defaults to None. |
None |
parameters |
dict |
Optional dictionary of query string parameters to include in all requests. Defaults to None. |
None |
ignore_conformance |
bool |
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. Defaults to False. |
False |
modifier |
function |
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. Defaults to None. |
None |
request_modifier |
function |
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. |
None |
stac_io |
pystac.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. |
None |
return_col_id |
bool |
Return the collection ID. Defaults to False. |
False |
get_root |
bool |
Get the root link of the STAC object. Defaults to True. |
True |
**kwargs |
Additional keyword arguments to pass to the pystac.Client.open() method. |
{} |

Search a STAC API. The function wraps the pysatc_client.Client.search() method. See https://pystac-client.readthedocs.io/en/stable/api.html#pystac_client.Client.search
Parameters:
Name | Type | Description | Default |
---|---|---|---|
url |
str |
The STAC API URL. |
required |
method |
str |
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. Defaults to "POST". |
'POST' |
max_items |
init |
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. This parameter defaults to 100. Setting this to None will allow iteration over a possibly very large number of results.. Defaults to None. |
None |
limit |
int |
A recommendation to the service as to the number of items to return per page of results. Defaults to 100. |
100 |
ids |
list |
List of one or more Item ids to filter on. Defaults to None. |
None |
collections |
list |
List of one or more Collection IDs or pystac.Collection instances. Only Items in one of the provided Collections will be searched. Defaults to None. |
None |
bbox |
list | tuple |
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. Defaults to None. |
None |
intersects |
str | dict |
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. Defaults to None. |
None |
datetime |
str |
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. Defaults to None. |
None |
query |
list |
List or JSON of query parameters as per the STAC API query extension. such as {"eo:cloud_cover":{"lt":10}}. Defaults to None. |
None |
filter |
dict |
JSON of query parameters as per the STAC API filter extension. Defaults to None. |
None |
filter_lang |
str |
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. Defaults to None. |
None |
sortby |
str | list |
A single field or list of fields to sort the response by. such as [{ 'field': 'properties.eo:cloud_cover', 'direction': 'asc' }]. Defaults to None. |
None |
fields |
list |
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. Defaults to None. |
None |
get_collection |
bool |
True to return a pystac.ItemCollection. Defaults to False. |
False |
get_items |
bool |
True to return a list of pystac.Item. Defaults to False. |
False |
get_assets |
bool |
True to return a list of pystac.Asset. Defaults to False. |
False |
get_links |
bool |
True to return a list of links. Defaults to False. |
