Minimize Land Overview

Earth’s land surface represents the most varied terrain in the whole of the Solar System, gradually transformed by geological motion, atmospheric weathering and sustained biological activity. Its evolution continues to this day, helped along by humanity: deserts expand, forests are cleared and cities grow.

Satellite instruments allow land cover to be classified on an objective global basis, and identify land cover change. They can pinpoint wilderness areas under threat from sprawling settlements, for example, or track patterns of soil erosion. And land cover classification sharpens the accuracy of climate models: pinning down the contributions of localised carbon ‘sources’ and ‘sinks’ for example, or the varied albedos of differing biomass or mineral surfaces.

Other types of instruments contribute more radiometers such as Envisat’s AATSR takes the temperature of Earth’s land, while radar altimetry and synthetic aperture radar interferometry build up accurate three dimensional maps of its surface contours.

OECD uses ESA data to measure green growth

06 September 2018

ESA data have been used to develop the new Organisation for Economic Co-operation and Development Green Growth headline indicator on land-cover change.

The Organisation for Economic Co-operation and Development (OECD) defines green growth as ‘fostering economic growth and development, while ensuring that natural assets continue to provide the resources and environmental services on which our well-being relies.'

Copernicus Sentinels to help measure Earth's biomass

07 June 2018

The amount of carbon stored in Earth's forests and how it is changing will be measured in the forthcoming Climate Change Initiative Biomass project, in which the legacy of GlobBiomass will be carried forward to the Sentinels' era.

Soil

The monitoring of soil moisture on a large scale for the purposes of hydrological modelling and water management form the major element of this application. In addition research is aimed at understanding both soil chemistry and processes.

Topography & Mapping

Interferometry is one of the key techniques in the creation of digital elevation models for the mapping of large areas and in the monitoring of elevation change in areas of land subsidence or uplift.

Urban & Industry

There are an ever increasing number of applications in support of industrial development from civil engineering to oil prospecting, and in the monitoring of urban change and population mapping for planning and control purposes.

Vegetation

The extensive mapping of vegetation and its condition form key elements of programmes aimed at the development of national and international food policies. Whilst ongoing research studies the more detailed biophysical processes.

Wetlands

The world's wetlands form a unique environment for natural species, but due to their fragility they are evermore under pressure. The study of the environment and the change elements which affect them are the core of this application area.
