How spatial data is being used in natural resources & environmental applications. Canada is big. Our watersheds and forest corridors cover vast areas, often spanning several administrative regions. For this reason, it can be difficult to effectively monitor and communicate the conditions of the environment as it changes, and also difficult to reach consensus on a plan of action and coordinate on policies between jurisdictions. Lack of coordination between regional governing bodies, short sighted planning and rapid land development have been the peril of the natural environment over the last 100 years or more. Habitat loss, erosion, soil and groundwater depletion and contamination have all taken a toll, and now ambitious plans to mitigate further damage are needed to aid recovery, not just for the intrinsic value of nature, but also for the sustainability of food production, water, air and climate.
