- Description
This is the final programme of the 3-part series focusing on images of our earth taken from space. This programme focuses on how satellite data can be used to provide information on phenomena such as ozone levels, sea temperature and complex topography in order to make virtual maps of the Earth.
The 5-minute A-roll contains split audio with an English guide track and is complemented by a B-roll with international sound only.Earth Views III : ""What the Eye can't See""

Satellite instruments not only enable us to generate images of phenomena which would not otherwise be visible. Those images can then be combined and interpolated to build complex models over time.
WHAT THE EYE CAN'T SEE
As they continually orbit the earth, satellites pass many times over the same or related areas. The data collected from a single area can be grouped in a multi-temporal set, which scientists may then use to build both complex models of phenomena and even to make forecasts

Satellite readings also enable incredibly accurate digital models of complex terrain, as seen in this model of Iceland, for which satellite readings are taken through cloud cover and snow, then interferometry is used to build a precise surface model.
