Digital line graph (DLG) data are digital representations of
cartographic information. DLG's of map features are
converted to digital form from maps and related sources.
Intermediate-scale DLG data are derived from USGS
1:100,000-scale 30- by 60-minute quadrangle maps. If these
maps are not available, Bureau of Land Management
planimetric maps at a scale of 1: 100,000 are used.
Intermediate-scale DLG's are sold in five categories: (1)
Public Land Survey System; (2) boundaries (3)
transportation; (4) hydrography; and (5) hypsography. All
DLG data distributed by the USGS are DLG - Level 3 (DLG-3),
which means the data contain a full range of attribute
codes, have full topological structuring, and have passed
certain quality-control checks.
DLG's depict information about geographic features on or near
the surface of the Earth, terrain, and political and administrative
units. These data were collected as part of the National Mapping
Program.

Refer to Positional_Accuracy element.
Topological requirements include: lines must begin and end at
nodes, lines must connect to each other at nodes, lines do not
extend through nodes, left and right areas are defined for each
line element and are consistent throughout the file, and the
lines representing the limits of the file (neatline) are free of
gaps.
The tests of logical consistency were performed by the USGS
PROSYS program. The neatline was generated by connecting the
four corners of the digital file, as established during initialization
of the digital file. All data outside the enclosed region were ignored
and all data crossing these geographically straight lines were clipped at
the neatline. Data within a specified tolerance of the neatline
were snapped to the neatline. Neatline straightening aligned the
digitized edges of the digital data with the generated neatline,
that is, with the longitude/latitude lines in geographic
coordinates. All internal areas were tested for closure using
PROSYS.
For Digital Revision Status = Not revised
Data completeness reflects the content of the source quadrangle.
Features may have been eliminated or generalized on the source
graphic, due to scale and legibility constraints.
For Digital Revision Status = Limited Update
This file has undergone limited update digital revision. The
file contains only (1) those features that are photoidentifiable
on monoscopic source, supplemented with limited ancillary source,
and (2) those features, present on the original source quadrangle,
that can not be reliably photoidentified but that are not
considered particularly prone to change.
For Digital Revision Status = Standard Update
This file has undergone standard update digital revision. The
data completeness of this file meets NMD standards for feature
content.

For Digital Revision Status = Not digitally revised:
This Digital Line Graph was digitized from the USGS source
quadrangle, by either the National Mapping Division, one of
their cooperators, or one of their contractors. The digital data
were produced by one of the following methods:
- scanning a stable-based copy of the graphic materials.
The scanning process captured the digital data at a
scanning resolution of at least 0.001 inches; the
resulting raster data were vectorized and then attributed
on an interactive editing station.
- scanning the paper map. The scanning process captured
the digital data at a scanning resolution of at least
0.001 inches; the resulting raster data were vectorized
and then attributed on an interactive editing station.
- scanning a stable-based copy of the graphic materials.
The resulting raster data were then manually digitized
and attributed on an interactive editing station. The
resolution of the digital data is at least 0.001 inches.
- scanning the paper map. The resulting raster data were
then manually digitized and attributed on an interactive
editing station. The resolution of the digital data is
at least 0.001 inches.
- manually digitizing from a stable-based copy of the
graphic material using a digitizing table to capture the
digital data at a resolution of at least 0.001 inches;
attribution was performed either as the data were
digitized, or on an interactive edit station after the
digitizing was completed.
- manually digitizing from the paper map using a digitizing
table to capture the digital data at a resolution of at
least 0.001 inches; attribution was performed either as
the data were digitized, or on an interactive edit
station after the digitizing was completed.
The determination of the DLG production method was based on
various criteria, including feature density, feature
symbology, and availability of production systems. Four
control points corresponding to the four corners of the
quadrangle were used for registration during data
collection. An eight parameter projective transformation
was performed on the coordinates used in the data collection
and editing systems to register the digital data to the
internal coordinates used in PROSYS, and a four parameter linear
transformation was performed from the PROSYS internal coordinates
to Universal Transverse Mercator (UTM) grid coordinates. The DLG
data were checked for position by one or more of the following
processes:
- comparing plots of the digital data to the graphic source.
- comparing the digital data to the digital raster scan.
DLG data classification was checked by at least one of the
following processes.
- comparing plots of the digital data to the graphic source
- comparing the digital data to the digital raster scan.

DLG3 attribute codes are used to describe the physical and cultural
characteristics of DLG node, line, and area elements. Attribute codes
are used to reduce redundant information, provide enough reference
information to support integration with larger data base, and describe
the relationships between cartographic elements. Each DLG element
has one or more attribute codes composed of a three digit major code
and a four-digit minor code. For example, with the 1: 24,000-scale DLG
data, the line attribute code 050 0412 has a major code (050), meaning
hydrography, with a minor code (0412) meaning stream.
