page 18 onwards for explanation of methodology
Originator:
Natural Resources Wales (NRW)
Is this an existing or new approach to measuring landscape change?:
Existing
Aspect of landscape:
Spatial coverage:
All Wales - approach to monitoring that could be used rather than data for the LD.
Geographical unit:
character area
Frequency of measure:
approx 10 years
Indicator:
landscape diversity and quality (value)
Resource requirements:
Data licence for OS and aerial photographs, satellite imagery can be sourced that is free to use but need specialist understanding and resource to run the comparisons between two time periods
Establishment cost:
Medium (additional staff time and limited cash up to £15k)
Any other comments:
happy to explain further if of interest
Ongoing operational cost:
covered in the above
Ongoing reporting cost:
interpretation of the data and reporting - could be stafff time or use contract
Data source:
Baseline and reporting units • LANDMAP relevant spatial dataset
For information and context • Ordnance Survey 1:50,000 and 1:25,000 • True colour aerial photography - assessment of land cover change • Wales Tranquil Areas Map • Phase 1 Habitat of Wales & Seasonal Change map of landscapes influenced by habitat change • Consented and Operational Wind farms • Additional information sourced relevant to each dataset • Professional and local knowledge from local authority input and specialists
For comparison over two time periods • OS MasterMap Roads and Buildings - changes in artificial structures and surfaces • Satellite imagery (e.g. Landsat 5, 7, Spot 2003) – Normalised Difference Vegetation Index (NDVI) - changes in living and non-living surfaces – Complexity Maps (Segment Density) - more/less/same landscape complexity • Mega Change Map - highlights the most significant changes
