# StackSTAC

[![Documentation Status](https://readthedocs.org/projects/stackstac/badge/?version=latest)](https://stackstac.readthedocs.io/en/latest/?badge=latest) [![Binder](https://mybinder.org/badge_logo.svg)](https://mybinder.org/v2/gh/gjoseph92/stackstac/main?labpath=%2Fdocs%2Fbasic.ipynb%3Ffile-browser-path%3D%2Fexamples)

Turn a list of [STAC](http://stacspec.org) items into a 4D [xarray](http://xarray.pydata.org/en/stable/) DataArray (dims: `time, band, y, x`), including reprojection to a common grid. The array is a lazy [Dask array](https://docs.dask.org/en/latest/array.html), so loading and processing the data in parallel—locally or [on a cluster](https://coiled.io/)—is just a `compute()` call away.

For more information and examples, please [see the documentation](https://stackstac.readthedocs.io).

```python

import stackstac

import pystac_client

URL = "https://earth-search.aws.element84.com/v1"

catalog = pystac_client.Client.open(URL)

stac_items = catalog.search(

    intersects=dict(type="Point", coordinates=[-105.78, 35.79]),

    collections=["sentinel-2-l2a"],

    datetime="2020-04-01/2020-05-01"

).get_all_items()

stack = stackstac.stack(stac_items)

print(stack)

```

```
