State of The (Manx) Map

The map of the Isle of Man is the featured image this week on OpenStreetMap so I think now is a good time for the State of The (Manx) Map post that I've been considering doing for a while. (Obviously borrowing ever so slightly from the name of the upcoming State of The Map conference in Manchester... have you registered yet?).

Overall coverage

The overall coverage of the Island is great thanks to the assistance of the Isle of Man Government, as you can see from the map below. Much of the detail from the government map has been included in the OpenStreetMap data, although I'm sure there are some features that have been overlooked to date.

The gaps in the map start to show when you zoom in to specific areas. Taking Douglas as an example, I'll show what level of detail is available and what will need local assistance (and possibly a mapping party) to get the town maps to a usable level of detail.

Douglas in detail

Douglas has the majority of its major routes mapped already, but it's missing a lot of the detail in between, like smaller roads, housing estates, pathways and the like. Where these do exist in the map already, they usually do not have a name associated with them, and almost never have all of the cul-de-sacs and such mapped out.

The likes of Castletown have more of their roads covered (it's smaller, and much easier to cover them) but likewise doesn't have the names of many of the smaller streets. Port St Mary is covered pretty well, including names, thanks to the support of one guy and his bike.

If you live in a place that's missing detail, you have an opportunity to help... Let's try and beat Google Maps to coverage of the Island!

Mapping party

If anybody from the Island is interested in doing some mapping (taking a GPS unit out and writing down street names as you go), especially around Douglas and Ramsey, then let me know. I'm likely to be back on the Island for most of the last week in August, so perhaps a little mapping party is in order then...

Isle_of_Man_map_wikipedia.pngOn a related note, it's great to see as well that some other free maps of the Isle of Man are surfacing on Wikipedia, licensed under a Creative Commons license.

Best of all, the image is in vector format and so can easily be altered to illustrate things with ease (it's perhaps a good starting point for the TT Course map I started last month).
