A data layer representing a complete hydrologic network, including transport arcs through wetlands, lakes, ponds, and double-line stream features, is a necessary component of many hydrologic applications. This paper describes an automated, AML-based process for creating transport paths. This process uses arc/node/polygon topology to select the start points for each path, GRID Euclidean distance and cost-surface functions to generate the paths, and ARCEDIT to add the transport arcs back to the original hydrography coverage(s).
