A conservation group is determining the most likely paths of movement for a population of bears in British Columbia, Canada. The study area is very large geographically with mountainous terrain and no roads, so the group will use distance analysis rather than sending a field team to observe the bears. Additionally, both slope and land cover are known to substantially affect the paths the bears prefer, so the group has developed a model of the bears' travel costs that accounts for these preferences. Which three modes of measurement are appropriate for this analysis? Choose three. Planar distance Cost-weighted distance Include barriers Geodesic distance Surface distance Straight-line distance
