Description

CLI Demo

The landsatxplore Python package provides an interface to the EarthExplorer portal to search and download Landsat Collections scenes through a command-line interface or a Python API.

The following datasets are supported:

Dataset Name	Dataset ID
Landsat 5 TM Collection 2 Level 1	`landsat_tm_c2_l1`
Landsat 5 TM Collection 2 Level 2	`landsat_tm_c2_l2`
Landsat 7 ETM+ Collection 2 Level 1	`landsat_etm_c2_l1`
Landsat 7 ETM+ Collection 2 Level 2	`landsat_etm_c2_l2`
Landsat 8 Collection 2 Level 1	`landsat_ot_c2_l1`
Landsat 8 Collection 2 Level 2	`landsat_ot_c2_l2`
Landsat 9 Collection 2 Level 1	`landsat_ot_c2_l1`
Landsat 9 Collection 2 Level 2	`landsat_ot_c2_l2`

Quick start

Searching for Landsat 5 TM scenes that contains the location (12.53, -1.53) acquired during the year 1995.

landsatxplore search --dataset landsat_tm_c2_l1 --location 12.53 -1.53 \
    --start 1995-01-01 --end 1995-12-31

Search for Landsat 7 ETM scenes in Brussels with less than 5% of clouds. Save the returned results in a .csv file.

landsatxplore search --dataset landsat_tm_c2_l2 \
    --location 50.83 4.38 --clouds 5 > results.csv

Downloading three Landsat scenes from different datasets in the current directory.

Downloading

landsatxplore download --help

Usage: landsatxplore download [OPTIONS] [SCENES]...

  Download one or several Landsat scenes.

Options:
  -u, --username TEXT    EarthExplorer username.
  -p, --password TEXT    EarthExplorer password.
  -d, --dataset TEXT     Dataset.
  -o, --output PATH      Output directory.
  -t, --timeout INTEGER  Download timeout in seconds.
  --skip
  --help                 Show this message and exit.

If the --dataset is not provided, the dataset is automatically guessed from the scene identifier. Note that only the newer Landsat Product Identifiers contain information related to collection number and processing level. To download Landsat Collection 2 products, use Product IDs or set the --dataset option correctly.

API

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

from landsatxplore.api import API

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

# Perform a request. Results are returned in a dictionnary
response = api.request(
    '<request_endpoint>',
    params={
        "param_1": value_1,
        "param_2": value_2
    }
)

# Log out
api.logout()

Please refer to the official JSON API Reference for a list of all available requests.

Searching for scenes

import json
from landsatxplore.api import API

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

# Search for Landsat TM scenes
scenes = api.search(
    dataset='landsat_tm_c2_l1',
    latitude=50.85,
    longitude=-4.35,
    start_date='1995-01-01',
    end_date='1995-10-01',
    max_cloud_cover=10
)

print(f"{len(scenes)} scenes found.")

# Process the result
for scene in scenes:
    print(scene['acquisition_date'].strftime('%Y-%m-%d'))
    # Write scene footprints to disk
    fname = f"{scene['landsat_product_id']}.geojson"
    with open(fname, "w") as f:
        json.dump(scene['spatial_coverage'].__geo_interface__, f)

api.logout()

Output:

4 scenes found.
1995-09-23
1995-08-22
1995-08-15
1995-06-28

Downloading scenes

from landsatxplore.earthexplorer import EarthExplorer

ee = EarthExplorer(username, password)

ee.download('LT51960471995178MPS00', output_dir='./data')

ee.logout()
