New York State Department of Transportation Map Information Unit Quadrangle Map Packets

Alphabetical by name of USGS quadrangle.

This series contains data used to update master overlay quadrangle maps maintained by the former Department of Transportation Map Information Unit. Contents of the map packets vary. Systematic weeding occurred at the time the quad map packets were transferred from the Dept. of Transportation (DOT) to the Office of Cyber Security & Critical Infrastructure Coordination (CSCIC). However, core materials, when present, were kept, as follows: All previous edition compilation manuscripts; and Current edition reviews of county highways, railroads, city schools, and current edition proof copies to DOT Regions and County Planning Offices but only if the information was not transferred to the compilation manuscript. These materials are not necessarily present in every packet. Materials relating to the original editions (ca. 1968-69) are sparse.

The quad map packets occasionally contain master transparencies which are the earliest, sharpest generation of the quadrangle maps. Data from master overlay maps is now revised and disseminated in digital format (paper quadrangle maps have not been updated for several years).

B2020Series B2020, Planimetric and topographic quadrangle maps, contains the final product of the data found in the quad map packets.

B2026-12: Container list, providing alphabetical range of quadrangles covered in each box, and item list of all quadrangles documented by the records, are available.

This series was transferred to the State Archives under Records Disposition Number (RDA) 20982.

There are no restrictions regarding access to or use of the material.
