This webinar will provide an in-depth look at leveraging open-access satellite data, aerial imagery, cloud computing, and open-source software to map and analyze surface water dynamics. We’ll start by exploring the wealth of freely available geospatial data sources, from Landsat and Sentinel satellites to high-resolution aerial imagery, that can be used to track surface water extent, flooding, and related changes over time.

Next, we’ll dive into cloud computing platforms like Google Earth Engine and open-source tools like the geemap Python library. These technologies allow us to efficiently process massive geospatial datasets and generate insights using just a browser. We’ll walk through practical examples using the powerful capabilities of these platforms, including time-series analysis and change detection.

To illustrate these techniques in action, we’ll showcase two recent high-profile flood events – the devastating 2022 Pakistan floods and the 2024 Brazil floods. Participants will learn how open data and cloud-based tools can be leveraged to rapidly map the spatial extent of flooding, monitor its evolution, and support relief and recovery efforts. The webinar will close with a Q&A session to address any questions from attendees.


  1. Identify and access freely available satellite data, aerial imagery, and other open geospatial datasets for surface water mapping and monitoring.
  2. Demonstrate proficiency in using cloud-based platforms and open-source tools to efficiently process and analyze geospatial data.
  3. Apply surface water mapping techniques to real-world flood events, such as the 2022 Pakistan floods and 2024 Brazil floods.
