Landslide locations and extents Ireland (ROI/NI) ITM

Landslide locations and extents help us locate where landslides have occurred. Ireland's location, terrain and climate result in landslides occurring mainly in areas with steep slopes where rock meets the surface and peat covers the terrain. Landslides have the potential to cause great havoc, and have done so all around the world. They have resulted in loss of life and damage to infrastructure. Landslides can damage roads, railways, canal embankments, and cause dams to fail. They can destroy or severely damage buildings of all types – housing, commercial or industrial property. Rivers can become blocked or diverted by sediment or rock displaced by landslides. A map of landslide locations can be used when planning large scale infrastructure projects such as roads, wind farms and housing. Understanding where landslides can occur will help prevent future damage to any structures built. A landslide is the movement of material down a slope. This includes rock, earth, mud and peat. Landslides in Ireland mainly occur on steep mountain slopes. Geologists map and record information on where and when landslides happen and on the material that has moved. To produce this dataset landslides were mapped using digital imagery and mapping in the field. We collect new landslide location data and update the landslide location dataset every year. This is a vector dataset. Vector data portray the world using points, lines and polygons (area). The landslide location data is shown as points. Each point holds information about the landslide event, its date, its location, the type of landslide (topple, bogslide, flow), the type of material (peat, earth, rock) and the cause of the landslide (heavy rainfall). he landslide extent perimeter data is shown as polygons which is the area of the landslide. Each polygon holds information about the landslide event, its date, its location, the type of landslide (topple, bogslide, flow), the type of material (peat, earth, rock) and the cause of the landslide (heavy rainfall).滑坡点位与滑坡范围可帮助我们精准确定滑坡的发生位置。爱尔兰的地理位置、地形与气候条件，使得滑坡主要发生在岩石裸露地表且覆盖泥炭的陡坡区域。滑坡具备极强的破坏性，全球范围内均曾发生滑坡灾害，已造成人员伤亡与基础设施损毁：其可破坏公路、铁路与运河堤岸，引发堤坝溃决；各类建（构）筑物——住宅、商用或工业建筑——均可能被摧毁或严重损毁；滑坡裹挟的泥沙与岩块还可堵塞或改道河流。滑坡点位图可用于公路、风电场与住宅等大型基础设施项目的规划工作，明晰滑坡易发区域则有助于预防后续新建建（构）筑物遭受滑坡破坏。 滑坡指物质沿坡面向下移动的现象，涵盖岩石、土体、泥浆与泥炭。爱尔兰境内的滑坡主要发生在陡峭的山坡地带。地质学家会对滑坡的发生位置、时间以及滑移物质进行测绘与记录。本数据集通过数字影像与野外测绘手段对滑坡进行测绘制图而成，我们每年都会采集新的滑坡点位数据并更新该数据集。 本数据集为矢量数据集（vector dataset）。矢量数据通过点、线与多边形（面域）来表征地理空间。其中滑坡点位数据以点要素形式呈现，每个点位包含滑坡事件的相关信息：事件发生日期、具体位置、滑坡类型（倾覆滑坡（topple）、泥炭滑坡（bogslide）、流动滑坡（flow））、滑移物质类型（泥炭（peat）、土体（earth）、岩石（rock））以及滑坡触发原因（强降雨（heavy rainfall））。 滑坡范围边界数据以多边形要素形式呈现，用于表征滑坡的影响区域，每个多边形同样包含上述滑坡事件的相关信息：事件发生日期、具体位置、滑坡类型、滑移物质类型以及滑坡触发原因。
