Mapped roughly the Peak District National Park.
Just rekindled my interest in OSM after years of absence did some basic stuff and decided I wanted something bigger to do.
I noticed that we are lacking huge national Parks in the UK on OSM.
The best way I though to do this was to import data but I couldn't find anything easy to do this job. So I did it by hand well from my computer.
Using the information now available from OSOpenData I roughly mapped the the Peak District. Using Potlatch 2 as my editor I have now got a good-ish rough approximation of the Peak District. It took hours but I did it.
The boundary lines on the OpenData I used were large - probably hundreds of meters across and guessed the best I could. Now it is up to me and other mappers to map the boundaries in more detail.
Enjoy. I might try adding more national parks soon to get some green on the map of the UK. :)
