Webinar - LCM2007 - The latest UK land cover map derived from satellite dataWebinar

The UK countryside is under pressure!
A growing population of over 61 million people needs space to live, to work, space for leisure and
recreation, places to bury or process waste, a transport network and raw materials for infra-
Mechanised agriculture, the use of pesticides and herbicides, driven by increasing demands for food
the economies of scale have squeezed wildlife into marginal and fragmented habitats. The services
these ecosystems provide such as clean water and insects to pollinate our crops are therefore under
The requirements of and the demands that we place on our terrestrial environment are often
and need to be managed and balanced to maintain and enhance our quality of life. But how? Before we
can begin to answer this question we need to take stock.
We need to know what we have on our land and where it is.
LCM2007 is the latest land cover map, produced by the Centre for Ecology & Hydrology. It has derived
from satellite images and digital cartography and gives land cover information for the entire UK.
cover is given as UK Biodiversity Action Plan Broad Habitats. Broad Habitats are the framework
which the UK Government is committed to meet its obligations for monitoring in the wider
LCM2007 is available in different formats to suit the various needs of users. The polygon
is the most detailed. Its spatial structure has been derived from national cartography: OS MasterMap
Great Britain and OSNI Large-Scale Vector for Northern Ireland.
Each polygon represents a parcel of land and has attributes describing land cover and meta data
describing about how this information was derived. Five raster products simplify this information. A
25x25m raster gives the most likely Broad Habitat for each pixel. Four freely available 1x1km raster
products summarise the 25x25m raster.
Previous CEH land cover maps, LCMGB 1990 and LCM2000 have been very successful and used in
numerous applications. LCM2007, through technological advances and the use of national cartography
has improved thematic and spatial accuracy over its predecessors.
These increase its potential uses and in conjunction with other data, LCM2007 will be a vital
component in the following sectors:
Atmosphere & climate
Water & catchments
Ecosystem service assessment
Marine & coastal
Ecology & conservation
Health & hazards
Education & publicity
The Centre for Ecology & Hydrology together with Defra will describe and discuss LCM2007 and ways
it can be used to help understand and manage the changing UK landscape.
