## Overview
[SpatioTemporal Asset Catalogs (STAC)](https://stacspec.org/) provide a standardized format that describes
geospatial information. Multiple platforms are using this standard to provide clients several datasets.
Platforms such as [Planetary Computer](https://planetarycomputer.microsoft.com/),
[Radiant ML Hub](https://mlhub.earth/) and [Google Earth Engine](https://earthengine.google.com/) use this standard,
however, only Google Earth Engine provides a fully easy API that is transparent for clients.
`easystac` is a Python package that provides users of STAC objects as well as clients from Planetary Computer and Radiant ML Hub
with an easy API that is transparent for them, implementing Google Earth Engine-like methods
and classes to query, explore and convert STAC assets to [`xarray`](https://docs.xarray.dev/en/stable/) objects.
Some of the `easystac` features are listed here:
- Simple authentication for Planetary Computer and Radiant ML Hub.
- Access to STAC collections from Planetary Computer and Radiant ML Hub.
- Earth Engine-like classes such as ImageCollection, including filtering methods.
- Compatibility with xarray.
Check the simple usage of `easystac` here:
```python
import easystac as es
from geojson import Polygon
geom = Polygon([
[
[-122.1553, 38.7578],
[-121.8321, 39.7444],
[-123.0002, 39.7503],
[-123.0002, 38.7609],
[-122.1553, 38.7578]
]
]
)
HLSS30 = (es.ImageCollection("HLSS30.v2.0")
.fromSTAC("https://cmr.earthdata.nasa.gov/stac/LPCLOUD/")
.filterBounds(geom)
.filterDate("2021-01-01","2022-01-01")
.getInfo(epsg = 4326,resolution = 0.0001,assets = ["B02","B03","B04"]))
```
In the case of specialized STAC objects, we have created special modules for Planetary Computer:
```python
import easystac.planetary as pc
from geojson import Point
pc.Authenticate()
pc.Initialize()
geom = Point([-76.1,4.3])
S2 = (pc.ImageCollection("sentinel-2-l2a")
.filterBounds(geom)
.filterDate("2020-01-01","2021-01-01")
.getInfo(resolution = 10))
```
This principle applies also for Radiant ML Hub.
```python
import easystac.radiant as rd
rd.Authenticate()
rd.Initialize()
S1floods = (rd.ImageCollection("sen12floods_s1_source")
.filterDate("2019-01-01","2019-01-05")
.getInfo(epsg = 4326,resolution = 0.0001))
```
