Abstract
 An ArcObjects Software-Based 3D Cross Section Tool for REALM Track: Water Resources Author(s): Thomas Heinzer, Diane Williams A new model, REALM (River, Estuary, and Land Model) is under development at the State of California Department of Water Resources. This effort is driven by the need to improve upon the functionality and performance of existing simulation models from a traditional water resources modeling standpoint. REALM will also incorporate management tools from other disciplines needed to solve the Department's and California's increasingly complex and difficult water issues in the Delta, tributaries, and bays. One component of this strategy is the implementation of a 3D cross section editing and analysis tool. When viewed in 3D, the bathymetric data are represented by a cloud of points. Using this cloud for reference, the analyst can digitize a cross section into georeferenced 3D space, resulting in a more representative cross section at any given reach interval. A summary of the methods and ArcObjects programming techniques employed will be presented.
