Preliminary Canadian Landslide Database

This preliminary landslide database includes 11,135-point features with assigned landslide type, material (surficial, rock, anthropogenic) type, point location type (headscarp vs. deposit), and qualitative location confidence (low, moderate, high). Where known, volume estimate, the date of occurrence, trigger, contributing factor, and reference are provided. The inventory contains both landslide events (discrete recorded period of movement) and landslide features (slope with morphology consistent with past or ongoing movement). No characterization of the current level of activity or hazard is provided.

The landslides have mostly been identified using Google Earth and publicly available lidar. Previously published landslide databases have also been incorporated and referenced. Landslide type attribution should be considered preliminary. Version 10.1 includes the addition of approximately 431 landslide features over version 10.0.

Point location and attribute data are provided as .csv file which can be imported in GIS software and as .kmz file for visualization in Google Earth. The .kmz file of version 10.1 also reverts to the landslide type symbology used in version 9.0.

Summary statistics are provided in a separate spreadsheet.

本初步滑坡数据库包含11135个点要素，附带已标注的滑坡类型、物质（表生、岩石、人为）类型、点位置类型（滑坡后壁与堆积体），以及定性位置置信度（低、中等、高）。在已知相关信息的前提下，数据库还提供了体积估算值、发生日期、触发因素、影响因子及相关参考文献。该编目既涵盖滑坡事件（即有记录的离散运动时段），也包含滑坡特征（即形态与既往或正在发生的运动相符的斜坡）。本数据库未对当前活动水平或灾害风险开展任何表征。

本次滑坡数据主要通过Google Earth与公开可用的激光雷达（LiDAR）数据识别得到，同时整合并引用了此前已发表的滑坡数据库。滑坡类型的属性标注暂定为初步结果。相较于10.0版本，10.1版本新增了约431个滑坡要素。

点位置与属性数据以两种格式提供：可导入地理信息系统（GIS）软件的.csv格式文件，以及可在Google Earth中进行可视化展示的.kmz格式文件。10.1版本的.kmz文件还恢复使用了9.0版本所采用的滑坡类型符号体系。

汇总统计数据另行提供于独立电子表格文件中。
