Paper
Rebuilding the Levees with GIS
Track: Database Design, Automation, and Management
Author(s): David McDaniel, Maik Flanagin, Michele Aurand

The USACE New Orleans District has historically segregated its levee data into individual survey files, CADD design drawings, and overview GIS layers. Although each dataset addresses a different niche of levee data management, no single comprehensive data source yet existed. Following Hurricane Katrina, requests for maps displaying levee designs and construction project locations were met by duplicating levee features for each new use. By associating surveyed traverse stationing to centerline reaches and surveyed elevations to centerline vertices, the District created a reusable Esri measure-based levee dataset. This dataset forms a comprehensive foundation that meets numerous levee management needs and supports an extensive array of decision-making requirements. Rather than redrawing levees, users can simply provide an event table for each attribution of the levees, such as construction, inspection, and design, using the official stationing. The new levee design eliminates time-consuming cartographic work and ensures consistent geometries across all attributions.
