Ordnance Survey Maps, One-inch Revised new series, England and Wales, 1892-1908

In this section

Content

The one-inch was a standard topographic authority and included a wide range of information on the physical and human landscape: land-use, industry, quarries, farms, inns, canals, parks and gardens, relief, woodland, and even smithies were all shown. The maps were of course considerably generalised compared to the six-inch maps, especially regarding buildings, towns and place-names. The outline maps especially were also useful for administrative purposes, and both civil parish and county boundaries were shown, reflecting the significant changes of the Local Government Act of 1888. The outline maps were also used as base maps for various other purposes, including geology, boundaries of petty sessional divisions, and for indexes to larger-scale OS mapping.

Different styles for three classes of metalled roads, and another for unmetalled tracks

One of the most important changes to the previous New Series sheets was a revised road classification. Metalled roads (ie. using compacted gravel) were divided into three classes, all distinguished from unmetalled roads or tracks. Single and multiple-track railways were distinguished, with the latter evolving to a new chequered symbol, distinguished from the standard ladder symbol for single-track railways. The Revised New series was the first to introduce the symbols for churches with towers and with spires, as well as the standard cross for churches without either. New symbols for windmills, lighthouses and lightships also appeared and from 1896, P (for Post Office) and T ( for Telegraph Offices) symbols were also shown.

Outline and Hills editions

The sheets of the Revised New Series were usually published both in an Outline form, with contours depicting relief, and as a Hills edition, printed with a second copper plate of brown or black hachures to depict relief. The standard contour interval was 50 feet, 100 foot intervals to 1,000 feet, and 250 foot intervals thereafter, although there was an additional 25 foot contour on some sheets covering Lancashire, Yorkshire and Lincolnshire. Some sheets never had any hills editions published, and some were only published with black hachures in the 1890s. We have tried on this website to create a seamless mosaic for circa 1900 of Outline and Hills sheets (with brown hachures) from our holdings, and therefore have had to use some later hills plates from the 3rd edition, published in the 1900s.

Sheet size

All the OS Revised New Series sheets have 12 x 18 inch extents of map sheets (A2 size for copying), apart from the Isle of Man sheet which was published as a full 36 x 24 inch sheet (A0 size for copying).
