UKCEH Land Cover Plus: Hedgerows 2016-2021 (England)

This dataset contains a model of the extent and height class of woody linear features on field boundaries in England, including hedgerows, tree lines and semi-natural thickets of shrubs and trees. The model was derived from processing of the Environment Agency lidar product (National Lidar Programme), captured in 2016-2021, and the linework is consistent with the polygon boundaries used in the UK Centre for Ecology & Hydrology (UKCEH) Land Cover Map (LCM). Due to expected low densities of woody linear features, and potential uncertainty, areas excluded from the coverage include LCM classes of mountain/moor/heath, open water and the coastal zone, urban/suburban areas and woodlands (i.e., areas of continuous non-linear woody cover). An area of approximately 24 x 25 km on the North Yorkshire Moors was also excluded from the model, as this area was not mapped by the EA lidar.

本数据集收录了英格兰田野边界上木质线性特征的面积和高度类别模型，包括树篱、树木行列和灌木树丛的半自然密集植被。该模型源自对环境署激光雷达产品（国家激光雷达计划）的处理，数据采集于2016-2021年，其线划与英国生态与水文学中心（UKCEH）土地覆盖图（LCM）中使用的多边形边界相一致。鉴于木质线性特征的预期低密度以及潜在的测量不确定性，排除在覆盖范围之外的区域包括LCM中的山地/荒原/草地、开阔水域及海岸带、城市/郊区以及林地（即连续的非线性木质覆盖区域）。此外，北约克郡摩尔的约24 x 25平方公里区域也未被纳入模型，因为该区域未由EA激光雷达进行测绘。关于本数据集的详细信息可查阅https://doi.org/10.5285/d90a3733-2949-4dfa-8ac2-a88aef8699be。
