Woody linear features framework, Great Britain v.1.0

A modelled dataset derived from a range of national datasets, describing the distribution of woody linear feature boundaries in Great Britain. The dataset presents linear features which have a high likelihood of being a woody linear feature. The dataset was created by a predictive model developed at the Centre for Ecology and Hydrology, Lancaster in 2016.

Provenance & quality

The dataset is the output from a model which classifies the attributes of each linear feature within a linear framework (based upon the simplified version of Ordnance Survey MasterMap).
The following approach was taken: Areas of the framework were masked out where woody linear features were unlikely to be found or where it would be impossible to detect them, i.e. where land was higher than 350 m, urban, wooded or in a coastal tide-washed area. OS Land-Form PANORAMA/LCM2007 were used to do this. Boundary height information was calculated from a DTM (NEXTMap 5m). Boundaries with woody linear features were identified from this calculated height data using thresholds for different vegetation height attributes for a given length of boundary, namely: minimum vegetation height -0.13 m (accounting for the presence of a ditch adjacent to the woody feature) to maximum vegetation height 58 m (the maximum height for a tree in GB), and mean vegetation height 0.58 m (accounting for gappy features). The dataset presents linear features which have a high likelihood of being a woody linear feature.
