Analyzing the Amazon Deforestation with ML and Google Earth – Part 1 | AI FOR GOOD DISCOVERY

Google Earth Engine combines data catalogue and processing capabilities, allowing the user to access vast amount of geospatial data and apply custom created processing scripts. The focus of the workshop is to apply machine learning algorithms for analyzing deforestation in the Brazilian Amazon using earth observation data, in particular multispectral images from ESA Sentinel and NASA Landsat missions. The workshop gives a general introduction to the Google Earth Engine cloud-computing service. Along basic functionalities we demonstrate how to browse and access the petabyte data catalogue. We also introduce the basic JavaScript in order for the user to be able to manipulate and handle data processing at a certain level. Going further into the workshop we will present how to compute indices such as NDVI (Normalized Difference Vegetation Index) and to analyze in a time-series manner. All the showcased steps eventually lead to a preprocessed set of scenes which are further used to apply a machine learning algorithm to quantify forest loss over time. Finally, the resulted products are evaluated against an external dataset.

Speakers:
Maria Antonia Brovelli, Professor of Geographic Information Systems and Digital Mapping, Politecnico di Milano
Vasil Yordanov, PhD candidate, ‘Vasil Levski’ National Military University

What is AI for Good?
The AI for Good series is the leading action-oriented, global & inclusive United Nations platform on AI. The Summit is organized all year, always online, in Geneva by the ITU with XPRIZE Foundation in partnership with over 35 sister United Nations agencies, Switzerland and ACM. The goal is to identify practical applications of AI and scale those solutions for global impact.
