A CLI for downloading, processing, and making a mosaic from Sentinel-1, -2 and -3 data

Sentinel Util

Sentinel Util is a command line utility to create a mosaic from Sentinel images.

Install

1. Install Conda (on linux, use curl -o install )
2. Install gcc
3. Install GDAL and Gippy v1.0.0b8 (and dependencies: swig, g++, etc.)
4. Make sure the conda installation of python is the default intallation
5. Download the repo

Use

python sentinel-util.py out bbox username password [-m mission] [-b beginning] [-e end] [-t type] [-p maxProducts]

out The folder where the image file will be written (i.e. /path/to/your/folder).

bbox Defines the bounding box in the form lat1,lon1,lat2,lon2, where each value is in decimal degrees. lat1 must be greater than lat2 and lon1 must be less than lon2 (i.e. the coordinate lat1,lon1 is the top left corner of the bounding box and lat2,lon2 is the bottom right corner).

username Your username for Copernicus Open Access Hub. Can be created here.

password Your password for Copernicus Open Access Hub. Can be created here.

-m mission The mission to download images from. 1, 2, or 3. Defaults to 1.

-b beginning If included, the mosaic will not incorporate images ingested before this date. Of the form yyyy-mm-dd (i.e. 1999-12-31).

-e end If included, the mosaic will not incorporate images ingested after this date. Of the form yyyy-mm-dd (i.e. 1999-12-31).

-t type For Sentinel-1 only, defaults to GRD.

-p maxProducts Default 100. Must be a positive integer ≤ 100. Limits the number of products downloaded.'

Alternatively, to run in the background and continue even after closing your terminal window (helpful for running on servers), run like nohup python sentinel-util.py [args] &

What will happen

1. It will download up to 100 products that match the search criteria
2. Each of the images in the products will be reduced from 16bit to 8bit and switched to WebMercator
3. All the images will be stitched into a mosaic
