What does this data set describe?

Title: l76_1m_dem
Abstract:
Northern communities and infrastructure in the Mackenzie Valley may be impacted by landslides and slope movements. In recent geological history of the Mackenzie Valley, hundreds of landslides, often affecting areas several hectares in size, have been identified and mapped. In order to improve the geoscience information in the Mackenzie Valley, Natural Resources Canada initiated a regional landslide mapping project to i) provide baseline knowledge on types, regional distribution, and controlling and aggravating factors of landslides in the Mackenzie Valley through a compilation of existing and new information; ii) assess the influence of environmental factors (e.g. forest fire, climate variability, global warming); iii) map and monitor zones of potentially unstable slopes using remote sensing technologies; and iv) map susceptibility to landslides in a permafrost environment.
