1:2,000,000-scale state boundaries of the conterminous United States

http://water.usgs.gov/lookup/getspatial?states2m
This coverage is of the state boundaries of the conterminous United
States. It was derived from the Digital Line Graph (DLG) files
representing the 1:2,000,000-scale map in the National Atlas of the
United States.
Boundaries
United States
This coverage is intended as a basemap for a variety of
applications.
Procedures_Used:
This series of maps was published as part of the National Atlas of
the United States (USGS, 1970). The maps for the conterminous
United States were digitized in 15 sheets and published in the
Digital Line Graph (DLG) format as described by Domeratz and others
(1983).
First, land polygon types were RESELECTed from COUNTY2M, then a DISSOLVE
on the item ST was run.
See the narrative for COUNTY2M for more information.
Revisions:

Process_Date 2/27/96
Reviews_Applied_to_Data:
This coverage has received no formal review. It has, however, been
used in numerous applications where serious errors would have been
obvious. Some state coverages were corrected following such use.
The offshore polygon extensions and the Canadian Great Lakes
polygons have had no review.
Related_Spatial_and_Tabular_Data_Sets:
This coverage is part of series of 1:2,000,000-scale basemaps
covering the United States. Layers in this set include:
COUNTY -- County boundaries.
STATE -- State boundaries (formed from COUNTY).
WATERBOD -- Water Bodies.
STREAM -- Streams.
HUC -- Hydrologic cataloging units (basins).

Attribute accuracy is described, where present, with each
attribute defined in the Entity and Attribute Section.
Polygon and chain-node topology present.
(Information in wordy narrative form describing omissions,
selection criteria, generalization, definitions used, and other
rules applied to derive the data set)
(An explanation of the accuracy of the horizontal coordinate
measurements and a description of tests used, if any, to
determine horizontal positional accuracy. This is different
from horizontal resolution as reported in the DOC file.
Positional accuracy defines how correctly the digital features
match real-world features and woiuld be related to the concept
of the National Map Accuracy Standard -- xx% of well-defined
point features fall within xx units of their true position.
The resolution is the smallest unit of measure the GIS can
reliably manage without truncation or rounding.)
approx. 1 km
Resolution as reported
(The same as above, but for vertical information that may
be encoded with the 2-D features such as cell or contour
estimates of a vertical dimension. A description of the
contour interval of input data and its basis could be described
here.)
