About this deal

The directions for making pavements given by Vitruvius. The pavement and the via munita were identical in construction, except as regards the top layer.

By 1991 the last significant, aid-funded mapping projects had been completed by OSD and all survey parties had been disbanded. OSD’s title was changed to OS International and its priorities turned to consultancy, mainly in Eastern Europe, while traditional map production gradually declined. Between 1946 and the late 1980s, Directorate of Overseas Surveys (DOS) field parties worked towards establishing ground control (planimetric and height) for mapping, observing national primary and secondary survey frameworks, and assisting with tertiary and cadastral control and levelling. The collection includes results of control surveys by other organisations, some connected to DOS schemes and most used by DOS in its mapping programmes.You can see this functionality in action if you choose one of the One Inch layers from the 1950s-70s. We sell a limited reproduction range of one inch to one mile maps (revised fromthe late 1800s and published in the early years of the 1900s) from our OSmap shop. We alsosell various historical products produced by our licensed Partners. Great Britain 1:1,000,000 (in the style of the International 1/1M. map) With the National Grid.

During the 1970s, government reviewed the DOS’ purpose. Then, in 1984, the organisation was merged with Ordnance Survey and given a new title: Overseas Surveys Directorate, OS (OSD). In addition to contract photography, the collection occasionally holds cover obtained by the national survey departments, and other aid agencies such as the Canadian International Development Agency. The example map sheets are held with full supporting records. Directorate of Overseas Surveys staff listsRAF photography at varying scales is held, along with Royal Navy photography. Additional records exist for more than one set of cover at various dates and is available for environmental research, geomorphology, vegetation, communications, and settlement, across a 40–50-year time span. The DOS maps from the collection have been re-located to RGS-IBG, which now holds a complete set designated as The Ordnance Survey International Collection (OSIC) Map Archive.
