Example applications

• A framework for carbon accounting
• LCM2000 provides
• A spatial framework for the landscape
• Land cover labels for each parcel
• A means for integrating disparate data sets
• A suitable landscape unit for models
• Results aggregated within a range of reporting
  units

Example applications
LCM2000 Level-2

Example applications
Carbon (t/ha)

Example applications
Carbon (t)
12
Example applications

• Catchment characterisation
• Relating land use to catchment hydrology
• Catchments can be characterised at a range scales
• Different catchments can be compared
• Field survey squares placed in a wider context
• Integration of channel measurements within actual
  catchment contexts

User perspectives

• The UK Land cover maps address
• A broad range of applications
• A large number of activity sectors
• Many stakeholders within and outside the CS
  consortium
• In excess of 600 users to date.

User perspectives

• Spatial structure
• OS framework provides
• MasterMap parcels
• Field level data objects
• Provides spatial consistency
• Better links to other data collection activities
• Habitat objects that better reflect management
  units

18
User perspectives

• Thematic content
• LCM2007 reports Broad Habitats
• An initial baseline
• what is there
• Opportunity potential to use LCM2007 for other
  habitat / land cover activities
• E.g. to infer Priority Habitats (1Many)
• E.g. local BAP reporting

19
User perspectives

• Metadata uses
• Object-level metadata
• Measures of sub-parcel variation uncertainty
• Can be re-worked to other link to other data

20
User perspectives

• User Summary
• Opportunity potential of LCM2007
• Provides a strong link to other data sets
• Can act as a framework within which base other
  data collection activities
• Can be re-cast to other classifications (CLC,
  NLUD)
• Extendable for easier revision and enhancement
• Allows more engagement with end user community
• Difficult to do this with previous land cover
  maps
• LCM2007 represents a watershed in national land
  cover mapping
