Mountain Legacy Project: Waterton Lakes - Riggal

The Mountain Legacy Project compiles historical survey photographs, maps and field notes created between years 1861 to 1953 by surveyors with the Geological Survey of Canada, the Department of the Interior’s Dominion Land Survey and other government departments. Repeated photographs of surveyed historical landscapes have been captured since 1998 onwards, in order to assess environmental change in the Canadian Rocky Mountains over the last century. This dataset compiles archival photographs and other objects from an undated Waterton Lakes survey by Riggal.

山地遗产项目（Mountain Legacy Project）汇编了加拿大地质调查局、内政部自治领土地测量局及其他政府部门的测量人员在1861年至1953年间创作的历史测量影像、地图与野外工作笔记。自1998年起，研究团队对已完成测绘的历史景观进行了重复拍摄，以评估过去一个世纪内加拿大落基山脉的环境变化情况。本数据集同时收录了里格尔（Riggal）所开展的未标注拍摄日期的沃特顿湖测量项目相关的存档影像及其他资料。
