Woody habitat corridor data in South West England
This dataset contains polylines depicting non-woodland linear tree and shrub features in Cornwall and much of Devon, derived from lidar data collected by the Tellus South West project. Data from a lidar (light detection and ranging) survey of South West England was used with existing open source GIS datasets to map non-woodland linear features consisting of woody vegetation. The output dataset is the product of several steps of filtering and masking the lidar data using GIS landscape feature datasets available from the Tellus South West project (digital terrain model (DTM) and digital surface model (DSM)), the Ordnance Survey (OS VectorMap District and OpenMap Local, to remove buildings) and the Forestry Commission (Forestry Commission National Forest Inventory Great Britain 2015, to remove woodland parcels). The dataset was tiled as 20 x 20 km shapefiles, coded by the bottom-left 10 km hectad name. Ground-truthing suggests an accuracy of 73.2% for hedgerow height classes.

- Statement
- The output data product has been ground truthed, suggesting an accuracy of 73.2% between field survey and modeled heghts of hedgerows (see documentation). The dataset has not been exhaustively checked for all errors. Extensive manual checking (comparison to aerial imagery) removed obvious anomalies, but many are likely to be remaining. Particular issues with misclassification of features at the coast resulted in all features within a 50 m buffer of the high water mark being removed. Some areas of tall in-field crops are probably also present as apparent low scrub, and difficulty in rendering very irregular patches of trees and scrub have created very dense or very simplistic areas of polylines.
