Identifying renewable energy resources is of paramount importance in reducing fossil fuel dependence and addressing climate change. The Rapid Hydropower Assessment Model (RHAM) uses GIS to identify hydroelectric power opportunities. Using a Digital Elevation Model (DEM) and regional hydrologic data, RHAM calculates the amount of hydroelectric power available on streams in a study area, screening out sites within parks and environmentally sensitive areas. RHAM also estimates project costs based on the historical cost of comparable projects. RHAM can also assess the suitability of hydroelectric development in a given area, taking into account economic, environmental and social factors, and can assess storage hydro and clustered developments. RHAM is currently being applied all over the world to unlock hydroelectric potential, reduce carbon fuel dependence, and help ensure a sustainable energy future for the world.
Since 1997, Esri Canada has been producing ArcNorth News, a free magazine distributed bi-annually to more than 7,000 subscribers. It is the only GIS publication dedicated to covering Canadian GIS successes using Esri technology.
