Will Phillips has built a website OSM-Nottingham which shows many groups of POIs in the Greater Nottingham area, and also allows address searches, and searches of local and national government open data sources for the area. The site also incorporates a range of historical map layers. This is a perfect one-stop shop for checking and visualising both OSM and open data in the Greater Nottingham area.

There are a few things which are familiar to regular and experienced mappers in Nottingham, which may not be obvious to those mapping during a visit or correcting and updating map data. Please pay particular attention to the following points:
ALIGNMENT WITH IMAGERY. Much of the area has been initially mapped from Yahoo aerial photography and is out of alignment by anything up to 20 metres. Other information is from old out-of-copyright maps and has a similar or greater degree of inaccuracy. A small part of the data has been realigned from GPS traces. This is a tedious and time-consuming process so has only been done when absolutely necessary to maintain topological relationships. Please be cautious before realigning any ways/areas to Bing imagery. It is best to check and realign the Bing imagery with available GPS traces before commencing editing. The Yahoo imagery was superseded by the more recent Bing imagery which is superior and covers the entire city. Most Bing imagery is 2013 until zoom level 20, when (better) images appear which are dated around 2008. The 2013 imagery does not cover the Northern edge of the City (checkout Tesco in Bulwell to see how confusing this can be). At the edge of the city some imagery is as old as 2001. You can examine the metadata associated with imagery tiles on JOSM. SK53 is in the process of setting up a grid of imagery offsets (initially at around 1km spacing) across the city for use with Zverik's imagery offset database.
NOTTINGHAM OPEN DATA. This is a fantastic resource, but if you are using it to add to OpenStreetMap, DO NOT USE ANY INFORMATION FROM THE MAP VIEW. Unfortunately the map view contains non-open data which requires a suitable licence from the Ordnance Survey. The only data which has this licence is that for Public Rights of Way. Some other data contains co-ordinates, often these are of the relevant postcode centroid. IT IS RECOMMENDED that this data is used as a source for driving surveys, or cross-checking against other sources (particularly useful if you remember a POI from a past visit & want to know if is still there before mapping it). Imports MUST be discussed with members of local community before any action is taken.
The highest quality data in OSM comes from the result of on-the-ground surveys. These can often be supplemented by other on-line material to enhance the surveyed data with features which it is difficult to observe accurately.
However, many parts of Nottingham, have been armchair mapped using a wide range of sources. These are discussed below, listed in a rough chronological order of usage.
Most of Nottingham was covered by Yahoo imagery: areas missing were Carlton, Gedling, Arnold, and everywhere N of Valley Road. Unfortunately the imagery had a significant displacement (around 10 metres) along a N-S axis, and much detail was added before this was realised. At the time it was not significant because the amount of really detailed mapping was limited, and the focus was on ensuring topological correctness. Over time this displacement has become more of a problem.
Areas outside the Yahoo imagery were often originally traced from NPE maps: for instance council estates in Bulwell, Sherwood and Bestwood. Virtually all of this has been replaced by subsequent realignment with Bing or OS Open Data, and in many places by GPS tracks and surveys.
NAPTAN data were imported for Nottingham and Nottinghamshire on 19 September 2009. Message from NAPTAN administrator read:
The NaPTAN bus stop data has now been uploaded for Nottingham and Nottinghamshire.
Details for merging the data with existing OSM data can be found on the wiki: NaPTAN/Surveying_and_Merging_NaPTAN_and_OSM_data
The data was used to derive road names in areas which were unmapped in 2009/2010. Of course, a standard OSM survey should be carried in the long run.
As of 2013-09 much of this data is now 4 years out of date and many nodes have not been re-surveyed to remove duplicates. A comprehensive check of this data in the city is needed.
OS Open Data
Available from 2010. Used to add road names to existing roads which had been arm-chair mapped. The ITO comparison layer and OSL Musical Chairs were used to hunt down missing roads at a later stage. Some areas, notably Top Valley and Rise Park were mapped entirely from OS Open Data (despite the notice above).
Some boundaries, mainly ward boundaries, were added from Boundary Line. Others, such as the Nottingham City Council boundary have not been corrected with this data.
A limited number of features were included from OS Vector Map District: mainly rivers as areas.
The availability of Bing imagery enabled much greater refinement of both existing areas, and particularly places which had not had any aerial imagery before. Bing provided very high resolution imagery (to z21) from around 2008. This allowed very detailed mapping of buildings. Around March 2014 these detailed zoom levels have disappeared and the new 2013 imagery is not of the same quality.
DoT Cycle Data
Nottingham Open Data
Over the past 2 years (from 2012), Nottingham City Council have released a large number of data sets under the OGL. Many of these have proved extremely useful as both sources of data for OSM, or as tools to drive particular surveys.
Public Transport Routes
List of relations and routes tagged in Nottingham at Nottingham/Public Transport
Major roads in the conurbation are in place, as are most areas with aerial photography - West Bridgford and Clifton are missing most road names, and the LCN/recommended cycle routes are marked in most of the city centre, and south of the Trent.
A more detailed picture of the current status by area (cake slice) is shown below.
The boundary of the city/unitary authority is complete but possibly inaccurate (see talk), ways which are part of the boundary are members of a relation.
More information on mapping particular features is on the Nottingham/Features page.
Kev - Lives in West Bridgford and mapping most of the area south of the Trent, particularly cycle routes - hoping to map these more fully when the weather gets somewhat warmer. NTU City and Clifton campuses have been mapped.
Rob - Did some of the major roads, and bits in Bramcote and Wollaton. Unfortunately not based in Nottingham, so only doing bits and pieces when visiting family.
Russ Phillips - Done some bits and pieces (some using Yahoo's aerial imagery). Not based in Nottingham, but has friends there, so visits sometimes.
Will Hebden - Working in Nottingham, so able to start filling in the city centre.
Will Phillips - Lives in Stapleford and primarily mapping the western suburbs of Nottingham and the surrounding countryside.
SK53 - Comes from Nottingham and is in the area frequently, usually maps on SW and W side of city.
Status by Area
Greater Nottingham area, has been split into 'cake slices' with the following outer boundaries: S.of the Trent, includes Nottingham City areas of Wilford and Clifton and the West Bridgford area of Rushcliffe district; N of the Trent, bounded to the W by the River Erewash (border of Notts and Derbys) until crossed by the M1, then by the M1 to Long Lane (Watnall), to the N by Watnall Road, A611, City Boundary (S of Bestwood Country Park) and then across country to Dorket Head, to the E from Dorket Head along Mapperley Plains, along Arnold Lane, Colwick Loop Road (A612) to the Trent at the Netherfield Railway bridge.
Colour and symbol legend
The status of each map region is indicated by a symbol, which describes the type of feature, and a colour, which indicates the completeness of that feature in a map region.
Meaning of symbols
- - Roads for car traffic are present. One way streets and pedestrian streets are present. This means that the map can be used for car navigation - Key: c
- - All public institutions are present (Churches, sports facilities, venues, schools, hospitals, city hall) - Key: p

|Cake Slice||District||Status||Remarks||Mapped / Checked by|
|1||City Centre||Good coverage. Some minor roads, narrow pedestrian ways (known locally as twitchells) and many POI missing.|
|2||The Meadows||Coverage is still patchy, but with the exception of an area near the library everywhere has received at least one survey visit. About 75% of the area W of Queens Walk has now been surveyed in detail: a huge number of intersecting footpaths and housing which bears little relation to its allocated street make the area quite complicated. All roads obvious from distributor roads are now labelled. Precise assignment and completion of addresses may only be possible once a house numbering scheme is under way. A small number (<10) of courts and named housing units not on streets may have been missed, but the street and footpath network is now adequate for routing, some address information is being collected and added for more recent surveys.|
|3||Lenton Lane||A mix of industrial estates, retail parks, with odd bits of greenspace. Mostly on land formerly occupied by the railways, and the long gone Clifton Colliery, Wilford Power Station, and the Royal Ordnance Factory.|
|4||Lenton||Predominantly residential area, more-or-less complete. Some tidying up needed around Canning Circus, and along Castle Boulevard. Some small mews type roads in The Park may have been missed. Restrictions on cars (oneway street, traffic calming etc.) in the streets around Harrington Drive needs to be checked.|
|5||Radford||Predominantly residential area, road network completely in place (90%). Areas re-developed since 1970 tend to have complex networks of roads and paths. Only two or three long straight streets, and gated areas have not been surveyed on foot with GPS. One or two unnamed streets remain, usually remnants of the former road network: the names can probably be inferred from old (out-of-copyright) maps.|
|6||The Forest||Mix of residential (many houses in multiple occupation), green space, with schools and some commercial. Most roads in place with names from OSSV. Patches (particularly in the NW quadrant) still need detailed ground survey, but most areas have been visited and street names verified by ground survey. Detailed mapping has taken place near the Lincolnshire Poacher on Mansfield Road, and most addresses are in place to the west of the Arboretum. Alfreton Road, Radford Road and Gregory Boulevard need surveying for retail POIs. Also worth looking for in-fill developments (for instance blocks of student flats), which may have different postcodes from the main street.|
|7||Mapperley Park||Most roads mapped from Yahoo and NPE data. Requires survey as there are many inaccuracies.|
|8||St. Anns||Only about 50% roads present: particularly in the area N of Woodborough Road, where the Yahoo aerial photos are difficult to interpret. Intricate network of footpaths only partially mapped.|
|9||Sneinton||Most roads present, with majority named.|
|10||West Bridgford and Edwalton||A very large area. All roads present, along with all street names. Buildings have been imported using the automatic extractor from OS OpenData StreetView, but address data is sparse.|
|11||Wilford, Silverdale and Compton Acres||All roads present, as are all streetnames in Rushcliffe (east of the line of the former Great Central Railway). The convoluted road system of the modern estate of Compton Acres has the rough road network in place but refinement is needed, the major paths are also in place, although some smaller ginnels may have been missed.|
|12||Clifton||Most roads present, with about 75% now named (SK53 13:52, 25 July 2009 (UTC)). Obvious POIs (Pubs and Churches) have also been augmented. Again the footpath network will present a challenge.|
|13||Dunkirk and Beeston Rylands||Mixed area of Industrial/Commercial with pockets of residential areas at Dunkirk and Beeston Rylands. The large area occupied by the Boots complex may be difficult to survey.|
|14||Beeston||Generally well covered, particularly around the town centre. Some gaps in outlying estates.|
|15||Nottingham University||Mapped in detail some time ago, but needs revision. One or two known roads are missing or not mapped correctly (e.g. Willoughby Close).|
|16||Wollaton Park Estate||
SK53 has been using this area to familiarise himself with several aspects of OSM. Most streets, footpaths etc. have been walked several times to generate GPS traces, and to acquire data for adding addresses according to the Karlsruhe scheme.
|17||Wollaton||All roads present and named. Network of footpaths largely complete, with some missing in Wollaton Park. Bus stops and routes about 50% complete.|
|18||Bilborough||Most roads present. Progressive additions from ground survey.|
|19||Broxtowe||Many roads present, although N part is off Yahoo imagery and much less complete. Broxtowe Country Park not mapped in any detail.|
|20||Hyson Green||Includes New Basford and Forest Fields. Most roads and street names present. The area N of Gladstone St requires work: many changes to original street layout, additional housing, and loss of industrial streets means that this area is particularly difficult to interpret from aerial photos. Requires ground survey.|
|21||Sherwood||Most roads present, but many from NPE are out of alignment in the N part of area. Requires ground survey.|
|22||Woodthorpe||Limited amount of ground survey, usually on route somewhere else. Many street names verified.|
|23||Gedling||First detailed survey work showed that NPE maps were still useful, although alignments will be wrong.|
|24||Carlton||As above for Gedling. POIs and street names added along length of Carlton Hill.|
|25||Colwick||Mix of industry along the main road, green space (park, country park and racecourse) and post-WWII housing (both social and private). No Yahoo photos for much of area. Colwick itself fully surveyed in Sept. 2009, with Netherfield also receiving much needed attention. Some initial surveys of other area (Bakersfield, Netherfield) have been done along main roads. Colwick Country Park and Netherfield Lagoons have been surveyed although are not complete, but Colwick Woods needs an initial survey.|
|26||Attenborough, Chilwell and Toton||Largely post WWII development other than the historical centres of the original villages. Some redevelopment of the Ordnance factory site. Most missing roads and street names were added during winter 2009-10.|
|27||Stapleford||Mostly complete (February 2011). Every road and street name is present. All addresses have been surveyed and house numbers are close to completion. However, there are a few instances where the correct number has yet to be ascertained.|
|28||Bramcote Hills and Wollaton Vale||Most roads present, and a few missing street names.|
|29||Strelley||Mainly open countryside, few roads. In a draft of a recent development plan this area was proposed for residential development.|
|30||North Bulwell||Again a lot of countryside, but some residential (Bulwell Hall & Seller's Wood Drive estates) and industrial areas (Blenheim Industrial Estate). Start finally made on this area. SK53 10:25, 3 August 2009 (UTC)|
|31||Bulwell||Complex mix of Victorian/Edwardian housing and industry, later infill, complete re-development and modern industrial estates. Also includes the former Cinderhill Colliery site. No Yahoo images, poor coverage. Some GPS traces for Bulwell centre, along Cinderhill road, and in the Bulwell Hall area. The Hempshill Vale estate has been completely mapped.|
|32||Basford||Surveying in Aug & Sep 2009 has improved coverage significantly. Whitemoor Estate and Basford Hall College site are the main areas lacking detailed ground survey.|
|33||Highbury||Poor coverage. A few street stubs and names grabbed on a drive thru. SK53 10:25, 3 August 2009 (UTC). Northern part surveyed by ~~ in Sept. 2009.|
|34||Bestwood Park and Daybrook||Poor coverage. In most areas roads have been sourced from NPE with limited surveying of road names. Most of the area S of Arnold Road/Oxclose Lane has been surveyed in detail.|
|35||Rise Park and Top Valley (inc. Rise Park and Top Valley)||Coverage is thorough but mainly from OSSV or Bing.|
|36||Arnold||Thanks to [User:Forumla1] coverage has improved considerably since 2011.|

The usual caveats apply w.r.t to copyright on these sites.
- Nottingam City Transport (NCT), Trent-Barton. List of main bus routes in city. Currently only about 5% implemented as relations.
- Pedals. A local Nottingham cycle advocacy group. The monthly meeting minutes contain a wealth of information relevant to mapping cycleways, particularly status, closures, changes.
- Nottingham Civic Society. Lists of historic buildings. Also have a footpaths officer.
- Ramblers Association, Nottingham Local Group. Comments as for Pedals above, but for footpaths.
- CAMRA, Nottinghamshire Group. Formidable amount of information on pubs and associated matters (particularly transport) in their bimonthly newsletter "The Nottingham Drinker". Useful for identifying the status of pubs.

- Notts local history. Site devoted to transcriptions of out of copyright works.
- Rise Park. Site about this area.
- Park Views. Range of opinion and information focusing on the Lenton and Dunkirk areas.
- Lenton Local History Society. Lots of useful stuff, including pages organised by street name.
- . Bulwell Hall Estate. Very useful information from the pages of a life-long resident.
Bits and bobs noticed whilst mapping, in no particular order.
- Bus Stops: Most are coded with one or two letters followed by a two digit number. Single letter stops are in the City Centre, two letter stops represent a code for an area (LE=Lenton,RA=Radford,GE=Gedling,CA=Carlton,Wo=Wollaton, etc.). Some stops outside the city have two letters and four digits, where the letters appear to code the local authority. Most stops have a name, which can be very useful for cross-checking other local map features.
- Lamp Posts: Seem to have unique 5 or 6 figure identifiers in the city. Seems to apply to other street furniture, e.g., bollards have a code starting with B.
- Bars and Pubs: Most establishments in the City Centre have a plate outside which states how many standing and sitting customers allowed by their licence. Could be useful to selective rendering.
- Postcodes: Short streets (i.e., those with a single postcode for the whole street) in Gedling Borough have the full postcode in red on the street signs. Also true for some streets in Broxtowe.
Development of OSM Coverage
Map from 2007, very little of the city had been mapped.
A massive change can be seen 20 months later.
- Stubs of roads in Rise Park, Top Valley and Bestwood Estate created, along with relations for 70 and 71 bus routes. SK53 12:53, 14 August 2009 (UTC)
- Detailed survey of Colwick village, and Industrial area by Simon Halsey. SK53 10:04, 5 September 2009 (UTC)
- Radford detailed survey completed. SK53 19:43, 8 September 2009 (UTC)
- S part of Gamston completed Simon Halsey, Netherfield partially surveyed Willumm. SK53 22:56, 11 September 2009 (UTC)
- Weekend 12/13 Sept. Part of Old Basford fully surveyed (SK53), new CentreLink bus service added (kevjs), missing roads in Edwalton added (Simon Halsey). SK53 09:37, 14 September 2009 (UTC)
- SK53 13:19, 25 September 2009 (UTC)
Relatively little progress
- Major progress in the Stapleford, Bramcote and surrounding areas. Largely the work of will7777.
- A fleeting visit in March from Steve Chilton produced some much needed updates on Nottingham University campus.
- Many missing street-names added from the Ordnance Survey Open Data StreetView set. Also some changes in status of main roads and references (particularly the A ). Where streets have been sourced from NPE the alignment has not been updated. This has been with a view to ensure that these areas get an 'on-the-ground survey'. SK53 09:04, 1 May 2010 (UTC)
- Some boundaries imported from OS OpenData BoundaryLine around Broxtowe District.
