EO For Beginners

In this video, from Imperative Space's ESA EO from Space the Optical View MOOC, Dr Hayley Evers-King explains the causes and effects of harmful algal blooms (sometimes also known as ‘red tides’), and how they can be monitored with satellite Earth observation. The ability to observe and anticipate the effects of such blooms can be of great benefit to a range of industries, (including tourism...

In this Video from the EUMETSAT MOOC "AI for Earth Monitoring" Dr Lauren Biermann, discusses how satellite technology, specifically Sentinel-2, is used to detect and track marine debris—such as driftwood and man-made waste—that poses navigational hazards. The satellite’s spectral capabilities allow it to distinguish between water and floating objects, making it valuable after events like flo...

About 4 billion hectares of forest cover remain globally. Increasing global demand for natural resources and more frequent extreme climate events drive global forest loss. Preserving forest cover is vital not only for the global climate but also for the ecosystem services which these forests provide, from provisioning to supporting, and regulating services. Provisioning services include materi...

Harmful Algal Blooms and coastal pollution can impact aquaculture, tourism and human health. The colour of the ocean is directly linked to the components of ocean waters that determine water quality. We intuitively understand what might be in water just by looking at its colour. This is something that’s long been investigated by those working on the sea, e.g. fishermen. Blue ocean water us...

This video is part of the ESA Network of Resources (NoR) Webinar series, and offers an introduction to the GeoHazards Exploitation Platform, developed by Terradue who are part of the GDA AID Disaster Resilience Consortium. The Geohazards Exploitation Platform or GEP aims to support the exploitation of satellite Earth Observation for geohazards.

Earth observation (EO) is a collective term for the gathering of data and information about our planet’s physical, chemical and biological systems through the process of ‘remote sensing’. Earth observation provides a way of monitoring the status of these systems and checking on their health. In essence, this is done by sensing and recording reflected or emitted electromagnetic radiation whic...

In this video, originally from the ESA EO from Space: The Optical View MOOC, Professor Mat Disney (UCL) explores the history and significance of optical Earth Observation, from aerial photography of earthquakes to satellite imagery that has transformed our understanding of environmental change.
