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.
