Overview

SpatioTemporal Asset Catalogs (STAC) provide a standardized format that describes geospatial information. Multiple platforms are using this standard to provide clients several datasets. Platforms such as Planetary Computer, Radiant ML Hub and Google Earth Engine 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 objects.

Some of the easystac features are listed here:

Check the simple usage of easystac here:

import easystac as es
from geojson import Point

geom = Point([-76.3,3.4])

E84_S2_L2A = (es.ImageCollection('sentinel-s2-l2a-cogs')
    .fromSTAC('https://earth-search.aws.element84.com/v0')
    .filterBounds(geom)
    .filterDate("2021-01-01","2022-01-01")
    .getInfo(resolution = 10,assets = ["B02","B03","B04"]))

In the case of specialized STAC objects, we have created special modules for Planetary Computer:

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.

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))
