TELECOM & UTILITIES
DEMs are efficient location and positioning tools as they eliminate guesswork during the capacity planning process for telecommunication and utilities companies. Generating line-of-sight, viewshed and height optimization from DEMs help determine optimum locations for infrastructure. Be it transmitters, cables, water pipes or wastewater treatment plants, engineers can perform tower backhaul, right-of-way mapping, signal-to-noise and propagation modelling using DEM data. Flood modelling and watershed analysis are customarily used by utilities companies to determine optimum locations for hydroelectric facilities, reservoirs and dams and power lines (above and below ground). The use of satellite imagery in conjunction with DEM can help refine the optimum positioning of assets by taking into account guidelines set by government agencies (e.g. required buffers or height requirements for power lines / radio towers in a built-up area). The use of satellite images extends as a visual tool to aid the communication process, facilitating quicker decision making by agencies. The ability to remotely view and monitor ground assets in near real-time via satellite imagery makes satellite imagery an efficient asset-tracking tool. Technicians and facility managers can pinpoint abnormalities and assess the need for follow-up on-site checks, reducing costly and time-consuming routine on-site checks.
