OTB Guided Tour : count the islands !
2021-09-27, 14:00–18:00, Nemonte Nenquimo

Orfeo ToolBox (OTB) is a reference remote sensing library, that provides tons of applications to deal with remote sensing images (satellite or UAV images) and extract valuable information into your GIS software.
This workshop is addressed to beginners with OTB, who want to start to use OTB in their own remote sensing and geomatic processings. You will manipulate a Jupyter Notebook and will learn how to use OTB Python interface, interactions with other frameworks (GDAL, Xarray, PostgreSQL), through a realistic processing chain.
During our "guided tour", you will use extracts of Sentinel-2 images over Morbihan gulf in south Brittany (France) and compute water masks to count the many islands in that area.


The workshop will start with an overview of Orfeo Toolbox (where to start, examples of different processing chains, etc.).
Then attendees will use a Jupyter Notebook with some cells to fill in or adapt. The purpose of the notebook will be to configure and use a small processing chain that will compute water mask by computing radiometric indices on Sentinel-2 images.
Prior to the workshop session, we will provide all the material through a virtual machine. We will also provide the dataset for people who want to use their own installation of Orfeo Toolbox.
