Planetary Computer SDK for Python

Python library for interacting with the Microsoft Planetary Computer.

Installation

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.

Development

The following steps may be followed in order to develop locally:

## Create and activate venv
python3 -m venv env
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
./scripts/test

Usage

This library currently assists with signing Azure Blob Storage URLs, both within PySTAC assets, and by providing raw URLs. The following examples demonstrate both of these use cases:

import pystac
import planetary_computer as pc

raw_item: pystac.Item = ...
item: pystac.Item = pc.sign_assets(raw_item)

# Now use the item however you want. All appropriate assets are signed for read access.

import planetary_computer as pc
import pystac

item: pystac.Item = ...  # Landsat item

b4_href = pc.sign(item.assets['SR_B4'].href)

with rasterio.open(b4_href) as ds:
   ...
