Landslide Inventory of North Carolina

Currently, this inventory is incomplete as mapping efforts and updates to older formats are still underway. Over time, this Feature Service will include every mapped landslide feature in North Carolina to date, as well as all future mapping efforts. The "Observations" layer identifies locations where landslides have impacted roads/structures or document’s locations where photographs or notes have been collected. "Ground Ruptures" are represented as lines indicating the extent of surface ruptures, which frequently serve as early indicators of landslides. The "Landslide Features" layer delineates the observed extent of mapped landslides. When feasible, landslides are classified into three phases: (1) initial slide (Source Area), (2) erosion or entrainment phase (Transport Zone), and (3) deposition phase (Deposit). This layer contains valuable fields such as confidence in existence and location, landslide type, and the storm events associated with each landslide. The following other Features Services will be adapted to fit this schema and appended to the dataset. North Carolina Post Helene Landslide Inventory (appended)当前本滑坡编目数据集尚不完备，因针对老旧格式的测绘与更新工作仍在推进中。随着工作推进，本要素服务（Feature Service）将涵盖截至目前北卡罗来纳州所有已测绘的滑坡要素，以及未来所有新增的测绘成果。「观测」图层（Observations layer）用于标记滑坡影响道路或建构筑物的点位，以及已采集照片或笔记的相关位置。「地面破裂」图层（Ground Ruptures）以线状要素标注地表破裂的波及范围，此类地表破裂通常是滑坡的早期预警标志。「滑坡要素」图层（Landslide Features layer）用于勾勒已测绘滑坡的实际波及范围。若条件允许，滑坡将被划分为三个阶段：(1) 初始滑动阶段（源区，Source Area）、(2) 侵蚀或裹挟阶段（运移带，Transport Zone）以及(3) 沉积阶段（堆积区，Deposit）。该图层包含多项关键属性字段，例如滑坡存在与位置的置信度、滑坡类型，以及各滑坡关联的风暴事件信息。后续其他要素服务（Features Services）将适配本数据集的数据架构（schema）并追加至本数据集。北卡罗来纳州海伦飓风后滑坡编目（North Carolina Post Helene Landslide Inventory）将作为追加数据集纳入本库。
