Riverine feature extraction from high-resolution imagery

Physical infrastructure designed and developed to enable this growth has been in place for 50 years or more, and an increasing proportion has reached the end of its design life. Taking dams for example, while the Canadian case is less well documented, 85% of U.S. dams will be >50 years old by 2020. In particular, decayed riverine infrastructure (e.g., dams, levees, bridge and pipeline crossings, etc.) has significant implications for public safety, economic and environmental health.
