Sprache: English

Have you ever found yourself wanting to use satellite imagery in your investigation but unsure where to start without relying on expensive subscription services?

Satellite images can help journalists investigate what is happening at a location at different points in time. Or they uncover hidden changes in the environment by capturing light waves not visible to the human eye. These techniques are applicable to a wide range of environmental investigations and OSINT tasks.

Google Earth Engine is an open-access, cloud-based platform for analyzing and visualizing satellite imagery and a wide range of geospatial datasets. It allows users to monitor environmental changes and run large-scale analyses without needing powerful local computers.

This workshop will cover:

  • How to set up Google Earth Engine (GEE)
  • Getting started with the GEE code editor and using built-in datasets
  • Accessing and viewing free satellite images from Landsat and Sentinel-2 missions
  • Understanding the basics of multispectral imaging and using false-color images to see more

This session is suitable for remote sensing beginners, but a basic familiarity with any programming language is a prerequisite.

Note: you will get the most out of this workshop if you register your Google Account for Earth Engine access ahead of the workshop - it is free but takes a few days to be approved. You will still be able to participate in this workshop either way: Register for Google Earth Engine
