Python automation for the ESA Copernicus Programme

Recently, I had the chance to play around with the Copernicus Python implementations. The package “sentinelsat“ contains a great Python API for automating the search and download procedure for Sentinel missions 1 to 3. The “snappy” package is a Python interface for running ESA Snap applications. The “snappy” package can be tricky to install, especially on company computers with limited rights, and the official documentation is also very limited. There is however a lot of help available in various blogs and forums.  Once installed most SNAP functions can easily be automated. With a combination of these two packages a simple script will download and pre-process a large amount of images overnight. The example below is a time-lapse of Sentinel-1 SAR images for the Irish National Ploughing Championships in Co. Offaly (first image from the 26th August, last image from the 1st October). While the low resolution somewhat limits what can be seen, the area of the NPC shows up very clear, as the growing white area in the middle of the image. As the site is prepared, increasing disturbance and the growing number of objects increases the sites back scatter properties making it brighter in the images.NPC_2018

I will hold a workshop on the “sentinelsat” and “snappy” packages on the second day of the Irish Earth Observation Symposium 2018 (6th to 7th December 2018 in the Teagasc Conference Centre, Ashtown). If you are interested, sign up early as places are limited.
