Further application details.

The post code, place name and road name data was published by Ordnance Survey in May/June 2014.
Extracts from "The Database of British and IrishHhills" v14 published 22/04/2014 (ref. http://www.hills-database.co.uk/index.html )

Four levels of Ordnance Survey map detail are accessible within the application relating to different zoom levels. At the lowest zoom levels an overview of Great Britain is provided.

At the third level of detail, the map clearly shows the landscape features relevant to its scale, including relief, boundaries, settlements, main communications and physical features. The map data for this detail level was published by OS in January 2015.

The most detailed zoom levels features a 1:250 000 scale map published by OS in January 2014. The map is derived from a small-scale, vector, digital mapping product. It clearly shows the landscape features relevant to its scale, including relief, cities, towns, many villages, motorways, A and B class roads, railways, rivers and some woodlands.
