Landslides dataset (5km Hex-Grid) version 8

The 5km Hex GS Landslides dataset shows a generalised view of the GeoSure Landslides v8 dataset to a hexagonal grid resolution of 64.95km coverage area (side length of 5km). This dataset indicates areas of potential ground movement in a helpful and user-friendly format. The rating is based on a highest level of susceptibility identified within that Hex area: Low (1), Moderate (2), Significant (3). Areas of localised significant rating are also indicated. The summarising process via spatial statistics at this scale may lead to under or over estimation of the extent of a hazard. The supporting GeoSure reports can help inform planning decisions and indicate causes of subsidence. The methodology is based on the BGS Digital Map (DiGMapGB-50) and expert knowledge of the behaviour of the formations so defined. This dataset provides an assessment of slope instability. Landslide hazard occurs due to particular slope characteristics (such as geology, gradient, sources of water, drainage, man-made constructions) combining to cause the slope to become unstable. Downslope movement of materials, such as a landslide or rockfall may lead to a loss of support and damage to buildings. Complete Great Britain national coverage is available.

该5公里六边形GS滑坡数据集呈现了GeoSure滑坡v8数据集在64.95平方公里（边长5公里）六边形网格分辨率下的总体视图。该数据集以便于用户理解的方式标示了潜在的地面运动区域。评级基于该六边形区域内确定的最高易损性级别：低（1级）、中等（2级）、显著（3级）。同时，也标示了局部显著评级区域。在此尺度下，通过空间统计进行的汇总过程可能导致对灾害范围的低估或高估。相关的GeoSure报告有助于指导规划决策并指出沉降的原因。该方法基于BGS数字地图（DiGMapGB-50）以及对该定义的地层行为的专业知识。本数据集提供了对边坡不稳定的评估。滑坡灾害的发生是由于特定的边坡特性（如地质、坡度、水源、排水、人造建筑）结合在一起导致边坡变得不稳定。物质的下滑运动，如滑坡或岩崩，可能导致支撑丧失和建筑损坏。完整的英国全国覆盖图已提供。
