  • Topography Layer is a detailed, intelligent, geographic database. It contains almost half a billion features from the built and natural landscape of Britain. Detailed and surveyed to a high degree of accuracy, the Topography Layer is continually revised to incorporate changes to the urban and rural environment. It consists of nine themes: land area classifications; buildings; roads, tracks and paths; rail; water; terrain and height; heritage and antiquities; structures; and administrative boundaries. The ITN Layer is a detailed, accurate and up-to-date digital dataset consisting of a Roads Network theme and a Road Routing Information (RRI) theme for Great Britain. The Roads Network contains road categories, from motorways and primary routes to named and unnamed minor roads and local streets. RRI contains features such as height, weight and width restrictions; traffic calming; turn restrictions; and one-way roads as well as vehicular access and time restrictions. Other OS Layers – not available within Digimap Address Layer The most complete national address dataset for the whole of Great Britain. Imagery Layer The OS MasterMap Imagery Layer is a maintained dataset of  high-quality aerial photography and provides a detailed aerial map of Great Britain.

    5. 5. OS Open Data ‘Create and support innovative, exciting ideas and applications using our mapping. With OS OpenData you can freely access a selection of the most detailed mapping datasets available for Great Britain.’ http://www.ordnancesurvey.co.uk/oswebsite/products/os-opendata.ht •Digimap OS Collection provides some of the OS Open Data sets – different terms and conditions apply to this data (can be used commercially). •When users download OS data from Digimap, a conditions document is included, which specifies if data is: – covered by Digimap licence – Covered by Open Data licence
    6. 6. Digimap’s Ordnance Survey Collection View and print PDF maps Download map data Query tools
    7. 7. Digimap’s Ordnance Survey Collection •Roam – fixed scale mapping. • 14 zoom levels, or views. • Each view uses an OS map data product, appropriate for that scale. • Print A4 to A0 PDF. • User can select print scale. •Carto – user selects scale of map. Print A4 to A0 PDF. To be withdrawn July 2013.
    8. 8. Roam
    9. 9. Historic Digimap Ancient Roam – timeline allows you to view maps from different decades Access to land use maps from 1930s. Historic Download tool – download 3 different map series
