FeLS 1.3.5

Fetch Landsat & Sentinel Data from google cloud

FeLS - Fetch Landsat & Sentinel Data from google cloud

Find and download Landsat and Sentinel-2 data from the public Google Cloud

The script downloads the index.csv file listing all available Landsat or Sentinel-2 tiles, then searches the file for one scene that matches user parameters. Once found, it downloads the image files.

Developed with/for Python 2.7 and 3.3+ You may either install the package through pip:

pip install fels

or if using a conda environment, the following steps are recommended to create and install dependencies: conda create --name fetchLSGC python=3 Switch to the new environment (source activate fetchLSGC in Linux), and install the gdal dependency from conda-forge conda config --add channels conda-forge conda install gdal

Usage examples:

• LINUX:

fels 203031 OLI_TIRS 2015-01-01 2015-06-30 -c 30 -o ~/LANDSAT --latest --outputcatalogs /tmp

fels 44UPU S2 2016-10-01 2016-12-31 -o ~/SENTINEL2 -l --outputcatalogs /tmp

• WINDOWS:

fels 203031 OLI_TIRS 2015-01-01 2015-06-30 -c 30 -o %TEMP%\LANDSAT --latest --outputcatalogs %TEMP%\LANDSAT

fels 44UPU S2 2016-10-01 2016-12-31 -o %TEMP%\SENTINEL2 -l --outputcatalogs %TEMP%\SENTINEL2

Options:

-h, --help show this help message and exit

-s SCENE, --scene=SCENE TileID of scene (ex. 198030 for Landsat or 44UPU for Sentinel2)

-d START_DATE, --start_date=START_DATE start date, fmt('2013-12-23')

-f END_DATE, --end_date=END_DATE end date, fmt('2013-12-23')

-o OUTPUT, Where to download files

-c CLOUDS, --cloudcover=CLOUDS Set a limit to the cloud cover of the image

-b BIRD, --sat=BIRD Which satellite are you looking for. Available options are: TM, ETM, OLI_TIRS, S2

-l LIST, Just list the urls found, don't download

-e EXCLUDEPARTIAL, Exclude partial tiles - only for Sentinel-2

--latest LATEST, Choose the most recent image(s) that meet(s) the search criteria

--noinspire, Do not rename output image folder to the title collected from the inspire.xml file (only for S2 datasets)

--overwrite, Overwrite files if existing locally

--outputcatalogs=OUTPUTCATALOGS Where to download metadata catalog files
