How about covering your area with land use data using yahoo/landsat? It's something I do occasionally at the end of the work day when I'm totally exhausted - it's a nice dumb work which helps my brain turn off. And it comes handy for various hiking maps (example of my area: http://www.openstreetmap.org/?lat=46.5045&lon=15.534&zoom=12&layers=0B00FTF).
Anyway, I find mapping footpaths in forests much more interesting than plain old residential streets and roads - fewer people tend to cover them and sometimes it turns out be a real adventure - getting lost or meeting http://en.wikipedia.org/wiki/Image:Wild_Boar_Habbitat_3.jpg Not to mention the health benefits ;) Igor Donald Allwright wrote: > > >At 9:00am on a Sunday morning, the meaning of "no cycling" on urban > >footpaths mysteriously disappears :-) > > Unfortunately the mud doesn't, which if Saturday is anything to go by > would have been a bit too much for my non-mountain bike :-) > > >The real challenge as has been pointed out is the white space without a > >nearby contributor.
