Least Cost Analysis calculates the time or energy required to cross land or water given the topography of a landscape and the speed of a boat. Using different starting locations (village sites, archeological sites, or resource use sites) Least Cost Analysis produces both cost and aggregate catchments. In cases where the destination is known, least cost paths can also be derived.
Inlailawatash conducted a Least Cost Analysis for the Kó’moks First Nation, whose traditional territory includes the eastern portion of Vancouver Island from the Salmon River watershed in the north to the Englishman River watershed in the south as well as the islands of Denman and Hornby and portions of the BC mainland. Click here (http://www.komoks.ca/maps) to view a map of their traditional territory.
The analysis was conducted using a number of traditional village sites as starting locations. Maps were then developed from this analysis showing the shortest travel times from villages. These maps reflect areas of historic and concentrated use and will be used to assist Kó’moks First Nation with risk assessments, referrals, and legal cases.
