Home Cartographic Research Projects Generalization Generalization for The National Map To meet the goals of The National Map the USGS must accept high-resolution data from local, State, and other sources and merge these data into a consistent framework at an appropriate resolution. To the extent possible, this process should be automated, transparent to users, and occur in real-time as part of The National Map Viewer or the data delivery system. Part of this process will require spatial data generalization.
