Digital line graph (DLG) data are digital representations of
cartographic information. DLGs 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 DLGs 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.
DLGs 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.

Oracle
The identification of features is provided by the
distinct electromagnetic energy it emits,reflects, or otherwise transmits. This is
called the spectral signature. Other signatures such as tone (lightness or
darkness), texture (surface roughness or smoothness), pattern,shadow, shape, and
size are as important. Thus, through the use of the thematic mapper sensor, such
elements as water features, soils, and vegetation can be identified and distinguished from
each other.
Topological requirements specify that: (1) lines must
begin and end at nodes; (2) lines must connect to each other at nodes; (3) lines do not
extend through nodes; (4) left and right areas are defined for each
line element and are consistent throughout the file; (5) and the lines
representing the limits of the file (neatline) are free of gaps.
The tests of logical consistency areperformed 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 are ignored and all data
crossing these geographically straight lines is clipped at the
neatline. Neatline straightening aligns the digitized edges of
the digital data with the generated neatline or the
longitude/latitude lines in geographic coordinates. All internal
areas are 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 a 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
cannot 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:
(1) Scan a stable-based copy of the graphic materials. The
scanning process captured the digital data at a scanning
resolution of at least 0.0001 inches; the resulting raster data
were vectorized and then attributed on an interactive editing
station.
(2) Scan 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.
(3) Scan 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.
(4) Manually digitize 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.

The determination of the DLG production method was based
on various criteria, including feature density, feature symbology,
and the 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: (1) Compare
plots of the digital data to the graphic source, (2) Compare the
digital data to the digital raster scan.
DLG data classification was checked by at least one of the
following processes: (3) Compare plots of the digital data to the
graphic source, (4) Compare 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 different
cartographic elements. Each DLG element has one
or more attribute codes composed of
a three-digit major code and a four-digit minor code.
