Summary
Abstract: This data set contains boundaries and tags for major geologic units in the
conterminous United States. In addition to the polygons representing the areal
extent of geologic units, it identifies boundaries of metamorphic provinces,
major faults, calderas, impact structures, and the limits of continental
glaciation. The data depict the geology of the bedrock that lies at or near
the land surface, ... View entire text

Quality The line attributes were manually checked by assigning unique line types to the
values and then plotting the data. The plots were then compared to the source.

The polygon attributes were checked by visually comparing the final colored
plots to maps at various larger scales. Polygon and node topology are present.
All polygons are ... View entire text
