Automated Data Integration in Support of The National Map

Data integration is a significant problem for The National Map. We propose to examine data integration from a layer-based approach, developing a conceptual framework based on resolution, geometric accuracy, and topological consistency, and apply it to five of The National Map data layers, digital orthoimages, elevations, land cover, hydrography, and transportation. From the experience with the layered approach and the data developed, we will examine a feature approach to integration based on a model previously developed and implemented as a feature library. We anticipate significant results leading to an automated approach based on the conceptual framework, the empirical results, and the use of those in metadata to drive an automated process.
