Working with Sentinel-1 data: pre-processing, georeferencing and exporting with SNAP

Basic processing of Sentinel-1 SAR datasets using ESA’s Sentinel-1 Toolbox

Scientia Plus Conscientia

In this second part of the Sentinel-1 tutorial we will go through some simple steps to pre-process, georeference and export the data we downloaded using the procedures described in the previous post. To this end, we will use SNAP (Sentinels Application Platform), a free software package that you can download here.

We begin by downloading and installing the SNAP software package from the above mentioned webpage. You will have to enter your name and e-mail address, and will then receive a message in your mailbox with a link to download the executable. Choose the one that is right for your specific platform. Installation is straightforward, at least in Linux, the platform I use. Important: at the beginning of the installation check the boxes that tell the program to also install the toolbox for Sentinel-1.

Start SNAP. It is fairly rich in options, but the graphical user interface is…

About WQ

I received my PhD (2013) in Remote Sensing, Earth and Space Science at the Dept. of Aerospace Engineering Sciences, University of Colorado, Boulder, USA, under a Fulbright fellowship. Currently, I'm an Assistant Professor in the Dept. of Space Science at Institute of Space Technology (IST), Islamabad, Pakistan, where I have been a founding member of the Geospatial Research & Education Lab (GREL). My general expertise is in Remote Sensing where I have worked with various remote sensing datasets through my career, while for my PhD thesis I specifically worked on Remote Sensing using SAR (Synthetic Aperture Radar) and Oceanography, working extensively on development of techniques to measure ocean surface currents from space-borne SAR intensity images and interferometric data. My research interests are: Remote sensing, Synthetic Aperture Radar (SAR) imagery and interferometric data processing & analysis, Visible/Infrared/High-resolution satellite image processing & analysis, Oceanography, Earth system study and modelling, LIDAR data processing and analysis, Scientific programming. I am a reviewer for IEEE Transactions on Geoscience & Remote Sensing, Forest Ecosystems, GIScience & Remote Sensing, Journal of African Earth Sciences, and Italian Journal of Agronomy. I am an alumnus of Pakistan National Physics Talent Contest (NPTC), an alumnus of the Lindau Nobel Laureate Meetings, a Fulbright alumnus, and the Pakistan National Point of Contact for Space Generation Advisory Council (SGAC). I was an invited speaker at the TEDxIslamabad event held in Nov., 2014. I've served as mentor in the NASA International Space App Challenge Islamabad events in April 2015 and April 2016.
