OpenStreetMap
Tuesday: started work on detailed mapping of Newmarket, Suffolk, dealing with the race course and the residential areas to the north and west. It'll take a while - population about 15,000 so about 15 hours of surveying of which I did about three this week, so maybe 5 visits should see it done. It's only 10 miles from home though, so a bit more accessible than the remaining bits of South Cambridgeshire out towards St Neots.
The racecourse and related paraphernalia involved quite a few tags I'd not needed to use before, but much of the rest of the town in this part is rather dull ex-council housing residential (there's also a large industrial area which I didn't really start on, straddling Exning Road).
Discovered the Newmarket end of NCN51, which leads from Exning all the way into Newmarket town centre, most of it entirely away from the road down a small stream valley, so that got me back to the station and got mapped into the bargain (someone had obviously tried before, but maybe got lost, as it tailed off in the middle of a housing estate).

Good to see more of the outlying towns/villages near Cambridge getting some attention. I've all but finished off Cottenham now and was thinking of tackling Soham in the next few weeks - which is in desperate need of some mapping. Out of interest, have you found an easy and practical way to record street names while cycling (which I presume is your normal method)?

Check out this diary: osm.org/user/Brian%20Schimmel/diary .
He describes "audio mapping" and this seems to be quite practical. I urged him already to publish the plugin for Josm. Maybe he needs some more motivation:-)

That's an interesting association between population and surveying time that I'd not thought of ... I take it the "population about 15,000 so about 15 hours of surveying" is a rule of thumb for urban areas. Do you have any other similar rules of thumb for other types of areas?
By surveying time -is that driving, cycling, or walking? Is that just the time out on the ground or does it include the time to put the data into OSM, make ways, tag things, etc?
I'm just wondering if there's something here in your experience that I could use to make an estimate of how much effort to map the area I am working in.
