Landslide perimeter

Extension of the landslide phenomenon as defined in the technical protocols of APAT concerning the National IFFI Project. The perimeter is classified according to the type of landslide, according to the Varnes classification. Often the perimeter of failure is obtained by the envelope of the different events of failure本数据集为遵循APAT关于国家IFFI项目的技术规程所界定的滑坡现象延展范围。该滑坡周界将依据滑坡类型，按照瓦恩斯（Varnes）分类法完成分类。多数情况下，失稳周界可通过历次不同失稳事件的包络线获取。
