The most detailed street-level open data vector mapping product available, OS Open Map – Local is a great backdrop over which to display and analyse your data.

This dataset is published as Open DataAn open dataset of all Unique Street Reference Numbers (USRNs) within OS MasterMap Highways Network, with an associated simplified line geometry representing the geographic extent of each USRN.What OS Open USRN provides you with:Essential identifiers for streetsOur Open USRN product contains USRNs across GB. They are the authoritative identifier assigned to and uniquely identifying streets and are essential for managing Great Britain's Highways. Once its allocated to a street record, a USRN will never change or be reused.Authoritative sourceThe USRNs in OS Open USRN are allocated by Highway or Road Authorities and Highway Bodies, under their statutory responsibility to maintain this information. This means you can have confidence you’re accessing an authoritative source of these identifiers.Complete USRN dataAll USRNs present in OS MasterMap Highways Network, are also included in this product – so you can be sure you’re not missing out.Share and link dataOS Open USRN will enable you to start sharing and linking together information about USRNs which you can visualise with a location.

High resolution scanned images of Ordnance Survey maps from 1932 and 1933 in .tif file format, and corresponding .pdf format versions of these.These show parts of Salford, including the former docks, and the western side of Manchester city centre. A0 sized poster prints of these maps were used as part of the Undiscovered Salford display in the Community Science Showcase at Manchester Science Festival's GameLab event. The event took place on 20/21 October 2018 at the University of Salford's MediaCityUK campus.Original files kindly provided by the Salford Local History Library from their archives held at the Salford Art Gallery & Museum.OS Copyright expires 50 years from the date of publication, hence these maps are copyright free.

Audience: PublicExtent: UKUpdate Frequency: MonthlyWe are releasing this without delay as part of our commitment to Open Data so that Open Street Map, Ordnance Survey and other cartographers can ensure that National Cycle Network data is as accurate and uniform as possible across all platforms.Our decisions about which on-road sections of the Network to reclassify or remove have been informed using objective criteria based on the best data available to the charity about the speed and volume of traffic.It is important to point out that we also rigorously sense checked all decisions to assess their strategic impact on the Network as a whole as well as on valued long distance routes. In some cases sections have been removed because they duplicated other sections, they were left isolated by nearby removals, or they added little value to the Network. As a priority, we have dealt with on-road sections where the volume and speed of motor traffic are difficult for some user groups.You can read more about the methodology we used in our Removal and Reclassification Methodology

This webmap contains the GB Cartographic style providing a consistent symbology from national scale to street level.The cartography is similar to the OS Open Carto, which is delivered as a raster tile layer, but as it is a vector tile layer it provides capabilities for customization and high-resolution display. This service contains data supplied by the Ordnance Survey in their Zoomstack product (data last updated June 2022)The map projection is British National Grid.Customise this MapBecause this is a vector tile layer, you can customise the map to change its content and symbology. You are able to turn on and off layers and change their symbols. You can open this style in the vector tile style editor, make your changes and save a copy of your modified style to use yourself.Please send any feedback to VectorTiles@esriuk.com

Colourful and easy to use, Bartholomew’s maps became a trademark series. The maps were popular and influential, especially for recreation, and the series sold well, particularly with cyclists and tourists. To begin with, Bartholomew printed their half-inch maps in Scotland as stand-alone sheets known as 'District Sheets' and by 1886 the whole of Scotland was covered. They then revised the maps into an ordered set of 29 sheets covering Scotland in a regular format. This was first published under the title Bartholomew’s Reduced Ordnance Survey of Scotland. The half-inch maps of Scotland formed the principal content for Bartholomew's Survey Atlas of Scotland published in 1895. Bartholomew then moved south of the Border to the more lucrative but competitive market in England and Wales, whilst continuing to revise the Scottish sheets. This Bartholomew series at half-inch to the mile, covered Great Britain in 62 sheets in the 1940s, Bartholomew’s first to cover Great Britain at this scale (their previous series covering Scotland and then England and Wales). The series provides an attractive and useful snapshot of 1940s Britain. By this time, Bartholomew had altered the range of information on their maps compared to the 1900s. There were more categories of roads, Ministry of Transport road numbers were added, and new recreational features such as Youth Hostels and Golf Courses. Bartholomew’s topographic information was gathered partly from original Ordnance Survey maps, and partly from information sent in to Bartholomew from map users. One important user community for Bartholomew were cyclists. From the 1890s, Bartholomew entered into a formal relationship with the Cyclists’ Touring Club, then numbering around 60,500 cyclists, proposing that club members supplied Bartholomew with up-to-date information. In return, Bartholomew provided the CTC with discounted half-inch maps. The relationship worked very well, turning CTC members into an unofficial surveying army, feeding back reliable and accurate topographical information which Bartholomew would then use to update their maps. You can read more about this and see selected letters from cyclists at: http://digital.nls.uk/bartholomew/duncan-street-explorer/cyclists-touring-club.html.

Usually Bartholomew made revisions the sheets right up to the time of publication, so the date of publication is the best guide to the approximate date of the features shown on the map. You can view the dates of publication for the series at: https://maps.nls.uk/series/bart_half_great_britain.html
