Satellite Imagery: First Steps

Hands-on

This talk will build participants’ knowledge of the available sources of satellite imagery, what their respective strengths are and how to use them effectively.

– Review of different sources: Planet, Sentinel-2, LandSat-7 and Maxar — we set out the main options in more detail in a recent Substack post.
– How to find the imagery at the time and place you are interested (using freely available sources).
– How to get around common obstacles when working with satellite imagery such as insufficient imagery, cloud cover and low-resolution captures.
– Beyond the visual — an overview of some of the analytical approaches and techniques that use data on frequencies that can’t be detected by the human eye. They can help us identify methane leaks, spot fires, or detect deforestation. We will look at some of these approaches and the resources available.
