Description:
Abstract: The DLG data files used to create this dataset are derived from the 1:2,000,000-scale maps contain selected base categories of cartographic data in digital form. The data files are derived from the sectional maps of the 1970 National Atlas of the United States of America. The Transportation category includes major transportation systems in three separate subcategories: (1) Roads and Trails, (2) Railroads, and (3) Cultural Features (Airports and Alaska Pipeline). This file contains only data pertaining to New York State.
Purpose: DLG's depict information about geographic features of political and administrative units. These data were collected as part of the National Mapping Program.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report: Originally tested by manual comparison of the source with hard copy plots.
Logical_Consistency_Report: The topological structure of each DLG file is fully validated by software. There are no extraneous intersections; that is, a line does not join or cross another line, or itself, except at a node. No line extends through a node. Polygon (area) adjacency is also validated; that is, area left and right topological attributes of lines are consistent throughout the file. The neatline is free of gaps. Validation of DLG data is performed for each category within a file.
Completeness_Report: Roads and Trails: Data completeness generally reflects the content of the original source graphic. Selective updating of the maps was done prior to digitizing. The Roads and Trails category includes Interstate and primary State highways. Railroads: Data completeness generally reflects the content of the original source graphic. Selective updating of the maps was done prior to digitizing. The railroads category of data includes main line and branch line railroads. Cultural features: Data completeness generally reflects the content of the original source graphic. Selective updating of the maps was done prior to digitizing. The Cultural features for New York State are limited airports.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report: Comparison to a graphic source or image source is used as control to assess digital positional accuracy. Cartographic offsets may be present on graphic, due to scale and legibility constraints. Data has been vertically aligned between categories of data.

Process_Step:
Process_Description: This file was originally digitized by the National Mapping Division based on the sectional maps contained in The National Atlas of the United States of America published by the USGS in 1970. At the time of digitization in the late 1970s, most of the information contained in the maps was updated, using the latest available source materials. The digital data were produced by manually digitizing from stable-based copy of the graphic material using a digitizing table with a resolution of 0.003 to 0.005 inches. The digital data were checked for position by visually comparing proof plots with the graphic source. The digital data were checked for classification by manually checking proof plots against code listings. This file has undergone digital revision. The digital revision uses ancillary source, with no field verification.

Process_Description: This file was processed from Digital Line Graph (DLG) format packaged using the Spatial Data Transfer Standard (SDTS), into Arc/Info coverage format and then exported into Arc/Info Interchange format (.e00) using Arc/Info ver. 7.1.2. This file was also reprojected from Geographic to Universal Transverse Mercator, with units converted from decimal degrees to meters. No revisions or corrections were made to the data in this conversion process.

Entity_and_Attribute_Information:
Overview_Description:
Entity_and_Attribute_Overview: 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.
