... This project will 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, the project will examine a feature approach to integration based on a model previously developed and implemented as a feature library.
