EarthExplorer API

landsatxplore provides an interface to the Earth Explorer JSON API. Please refer to the official (documentation) for possible request codes and parameters.

Basic usage

import landsatxplore.api

# Initialize a new API instance and get an access key
api = landsatxplore.api.API(username, password)

# Perform a request. Results are returned in a dictionnary
response = api.request('<request_code>', parameter1=value1, parameter2=value2)

# Log out
api.logout()

Searching for scenes

import landsatxplore.api

# Initialize a new API instance and get an access key
api = landsatxplore.api.API(username, password)

# Request
scenes = api.search(
    dataset='LANDSAT_ETM_C1',
    latitude=19.53,
    longitude=-1.53,
    start_date='1995-01-01',
    end_date='1997-01-01',
    max_cloud_cover=10)

print('{} scenes found.'.format(len(scenes)))

for scene in scenes:
    print(scene['acquisitionDate'])

api.logout()
