Python library for interacting with the Microsoft Planetary Computer.
For general questions or discussions about the Planetary Computer, use the microsoft/PlanetaryComputer repository.
pip install planetary-computer
If you have an API subscription key, you may provide it to the library by using the included configuration CLI:
planetarycomputer configure
Alternatively, a subscription key may be provided by specifying it in the PC_SDK_SUBSCRIPTION_KEY
environment variable. A subcription key is not required for interacting with the service, however having one in place allows for less restricted rate limiting.
The following steps may be followed in order to develop locally:

source env/bin/activate
## Install requirements
python3 -m pip install -r requirements-dev.txt
## Install locally
pip install -e .
## Format code
./scripts/format
## Run tests

This library currently assists with signing Azure Blob Storage URLs. The sign
function operates directly on an HREF string, as well as several PySTAC objects: Asset
, Item
, and ItemCollection
. In addition, the sign
function accepts a STAC API Client ItemSearch
, which performs a search and returns the resulting ItemCollection
with all assets signed. The following example demonstrates these use cases:
from pystac import Asset, Item, ItemCollection
from pystac_client import ItemSearch
import planetary_computer as pc
# The sign function may be called directly on the Item
raw_item: Item = ...
item: Item = pc.sign(raw_item)
# Now use the item however you want. All appropriate assets are signed for read access.
# The sign function also works with an Asset
raw_asset: Asset = raw_item.assets['SR_B4']
asset = pc.sign(raw_asset)
# The sign function also works with an HREF
raw_href: str = raw_asset.href
href = pc.sign(raw_href)
# The sign function also works with an ItemCollection
raw_item_collection = ItemCollection([raw_item])
item_collection = pc.sign(raw_item_collection)
# The sign function also accepts an ItemSearch, and signs the resulting ItemCollection
search = ItemSearch(
url=...,
bbox=...,
collections=...,
limit=...,
max_items=...,
)
signed_item_collection = pc.sign(search)
