Welcome to Mappa Mercia — a home for OpenStreetMap enthusiasts in the Midlands (England).

Since starting in July 2006 we have extensively mapped the Midlands region and have expanded the community of individuals and organisations that understand the benefits OpenStreetMap brings to the local region.

In 2013 we were delighted to host 300 people for the official annual OpenStreetMap conference, State of the Map (2013 website). More recently we have enjoyed working with Transport for West Midlands, Birmingham City Council and Amey. We look forward to many more great collaborations as HS2 is built.

See our dedicated website: for more OpenStreetMap related offerings.


We are a friendly bunch and anyone with an interest in OpenStreetMap (or maps in general) is welcome, so do please come along if you can. If you cannot make any of these locations feel free to propose alternatives throughout the Midlands for our summer calendar. During winter months we often retire to a warm pub in central Birmingham.

Mailing List

There is a West Midlands specific (+ East Midlands for the time being) mailing list for general discussion:

Mappa Mercia Website

A dedicated website for use by the OSM midlands community hosted at The site includes custom made maps and a blog - we welcome guest content. A big thank-you to Christoph and Stu for helping to build the website, and to blackadder for registering the domain.

Current Primary Mapping Focus

Mini-Project Notes and contributors
1 Blue Plaques separate render for Birmingham Civic Society. Tag with OpenPlaques UID, for example openplaques_plaque=15555.
2 Buildings Labelling of major buildings with names and heritage status (e.g is it a Listed Building?) and tracing every building from bing and labelling with an address. Andy has set the standard in Sutton Coldfield. Good tracking software available at - you have to choose the addresses option in the box which has a default setting of "geometry"
3 Footpaths Loads left to do almost everywhere. Also completing relations for major named footpaths: Heart of England Way need completing; Monarch's Way almost non-existent; A Coventry Way; North Worcestershire Path needs completing
4 Turn Restrictions Most are probably not entered as relations. We can't route through the West Midlands without them. There's a neat tool for verifying turn restrictions at which will then render nice German traffic signs(now it renders UK signs!) on the map.
5 Winter Maintenance - Road Gritting & Grit Bins Adding gritting routes and grit bin data from local authorities in the region. Birmingham, Walsall, Wolverhampton and Solihull complete: current focus is Coventry, Dudley and Sandwell - See /gritting for current update and tasks.
6 Sculptures & monuments We're the pilot region for the UK's Public Monuments & Sculpture Association PMSA) records (The database for the West Midlands can be found at Birmingham City Centre pretty well entered now - it's a good incentive to get out and map other things as well as the fun of tracking down the sculptures!
7 Utilities Power lines and pylons are pretty complete in Birmingham, Substations, sewage plants, gas venting stations, sewage pumping stations all need attention. Also the West Midlands has a dense network of underground pipelines for gas and oil, the latter emanating from the oil terminals at Kingsbury, BHX airport, Bromford (not sure about Bedworth). These can be traced by locating and mapping the pipeline markers
8 Land Use Built up areas look nice when they're rendered with land use colours. Mostly complete-just small pockets left to do and keeping up-to-date with changes e.g brownfield to construction to residential
9 Allotments Add internal service roads/ paths; buildings, etc. Add number of plots and presence of toilets from (in Birmingham) see pageAllotments Project. Pretty much complete.
10 Bicycle Parking BCC has provided its full list and details of all bicycle parking in the city. Contact Blackadder if you want access to the reference data to help map them all into OSM. There is a user page for this project here: Birmingham/Bicycle_Parking.
11 UTC traffic management data collaboration with Birmingham City Council. A joint bcc-mappamercia team is working on a prototype tagging scheme and editing a pilot SCOOT region in the city ( A SCOOT region is a collection of adjacent junctions and crossings)
12 defibrillators. 90 added by Central England Co-operative in 2016; "hundreds more planned for 2017"
