OpenOrienteeringMap (not to be confused with the new OpenOrienteering Mapper project) is an orienteering map of the UK and Ireland, based on OpenStreetMap data. There are three formats – “Street-O Plus” “Street-O Lite” and “Pseud-O”. Version 2 of OpenOrienteeringMap is now in beta.
The Street-O map formats contain the level of detail equivalent to Street-O maps used for informal orienteering races around the streets of London and other urban areas in the UK and around the world. The Pseud-O map is a less serious map (as the level of detail in OSM is not sufficient for “proper” orienteering maps) but attempts to emulate the look and feel of standard orienteering maps.
Both maps make (loose) use of the ISOM and ISSOM orienteering mapping specifications, particularly the colours and the styling. Measurements are less likely to be within spec, due to artistic considerations and limits of standard screen resolutions.
When first accessing the website, you start zoomed out. Pan and zoom to your area of interest, then zoom back in a few times until you start seeing the orienteering map. Alternatively you can jump to a UK postcode, by typing it in at the top right.
Because the maps are based on the “Tile Mapping Service/XYZ” standard, they are viewable only at fixed scales. The current scale is displayed on the bottom right of the map. The most relevant scales for orienteering are 1:7000 and 1:14000 – these are the scales you will see for the third and fourth-most zoomed in levels (16 and 15), assuming a 72dpi screen.
Some areas of the UK are still missing much detail. You can help build the free map of everything in the world by contributing to the OpenStreetMap project, by surveying your local area and adding the roads, land types and other data into the project. The data is then pulled into OpenOrienteeringMap on a fairly regular basis – I’m aiming for monthly, or daily in the long term, but will need prodding to do it at the moment!
OpenOrienteeringMap was available for the world for a while, but the rapidly increasing size of the OpenStreetMap dataset has made this no longer possible at this time. However a version for specific countries is part of my plans in the medium term.
You’ll need a modern browser (i.e. not IE6) to make full use of the site.
Note that I cannot help fix the data – this should be done with the editing tools in OpenStreetMap – however if you have made a significant improvement to an area and would like it reflected in OOM before the next data refresh, by all means let me know.
