Having bought a Nokia N810, which makes it easy to add waymarks, I revisited using continuous sound tracks in JOSM this week, meaning I don't have to have wires draped across my handlebars, nor keep pressing the pause button. Ideally I'll use a bluetooth mic and record on the N810 in future, but the sound quality isn't good enough that way yet.

So, I've reimplemented the rudimentary audio support in JOSM to thread the audio player, supply the usual controls, synchronise with waypoints and allow for a sampled set of waypoints when you can't create them explicitly, and to have a play head which follows your track in JOSM in real time. It makes audio mapping much easier both while surveying and while entering data.

Two further trips to Newmarket on 6th and 15th February completed firstly the industrial and residential areas of Studlands Park and the area east of Exning Road over to the river valley carrying NCN51, and then the village of Exning. Not only were the existing roads there woefully incomplete, but what was there was significantly wrong as well: wrong names and deviant tracks. Corrected now.

Secondly, completed the rather more sparse area of east and north east Newmarket: the large number of stables and studs mean that residential development is not very dense along Ely Road (A142) and Bury Road (the old A11 road). Moving round to the south-east, however, density increased again on the rising ground behind the town.

Battery on my Nokia N8109 ran out on both trips after 4 hours 10 minutes. Biked home after the first session via NCN51 all the way - it's a long way round and I got back exhausted. Second trip I did bus both ways, and the timing was perfect. However it does leave an area called Crockfords Park south of the railway and the old town south of the High Street still outstanding. One more trip will probably complete the town.

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).

Thursday: first mapping expedition for a while, but needed to get out of the house despite the poor weather.

There was a gap in the Duxford area along the A505 between Whittlesford and Fowlmere which encompasses the Imperial War Museum complex (not all of which is accessible), and a surprising amount of housing, some new, which is actually part of Duxford. Went a bit further west to capture the hamlet of Crishall Grange, Thriplow public waste recycling centre, and pet cemetery.

Then the weather cleared a bit so I headed south on my bike to Great Chesterford, which I've completed, and with a bit of time to spare for the train back, also did Little Chesterford.

The two large villages of Over and Willingham are on the outer edge of South Cambridgeshire, biunded by the River Ouse to the north. Over was partly done, but turned out not very well. There were several incorrect street names and there was a lot less done than I had thought from looking at the map. So I completed Over, and then did the rather larger village of Willingham, which had only the two through roads already present. The hamlet of Overcote is around the corner from Over on a long dead end road out to the river, where NPE marks a now long-gone ferry to the Pike & Eel pub on the other bank.

This is the first time I've encounteed any hostility mapping. I had a nasty man in maroon overalls threaten to set his dogs on me for having the presumption to come down his road, Mere Way in Willingham. And Willingham is completely swamped with cars - there's an unbeliveable amount of traffic for such a small village.

Surveyed the large village of Swavesey and the smaller villages of Boxworth, Elsworth, Conington and Knapwell on Friday. Cold but bright, so a good ride on the bike, but yet another puncture, tedious and meant I ended up in the dark.

Filled the last remaining gap west of Cambridge and east of the A1198 with the parishes of Caldecote, Bourn, and Caxton, and also the little village of Longstowe on the way. A really bright, clear winter's day. Saw a kingfisher on the bridge in Caxton, just after recording Kingfisher Way.

Completed the missing south-west corner of South Cambridgeshire up to the Suffolk border with a trip around the villages of West Wickham, Horseheath, Shudy Camps, Castle Camps and Bartlow, including the hamlets of Camps End, Cardinal's Green, Mill Green, and Streetly End.

This is a really boring area. The villages have virtually no facilities, other than a school in Castle Camps, and the pubs are shut at lunch time. Not a single shop. Landscape is dull. Why would anyone choose to live in this featureless area? - there's obviously lots of expensive houses.

Anyway, though they're all small villages, they add significantly towards completion of South Cambridgeshire.

A gorgeous day to be out for a bike ride, though I wish I'd brought my tourer because there are more hilly bits than I'm used to in the flat lands of Cambridgeshire. Lots of cycling between villages, and not that much mapping considering the time I was out for.

Completed the last three small villages in this unmapped pocket of South Cambridgeshire: Great Chishill, Little Chishill and Heydon, together with the nearby Hertfordshire village of Barley and Essex village of Crishall, and their connecting roads.

So now, all South Cambridgeshire villages are done in an arc from Linton east of Cambridge round to the south and up to Kingston in the west. However, there is some detail around the Imperial War Museum site at Duxford and in general along the A505 there (including the hamlet of Crishall Grange, done only from npe so far) remaining. Further east we have Bartlow, West Wickham and "The Camps" to do; further west, lots of stuff along and west of the Royston to Huntingdon Road (Papworth, Bassingbourn etc), Highfields-Caldecote, Bourn, and villages north and west of Cambourne. North of Cambridge, there's the Swavesey, Over, Rampton area.

Completed the town of Whaley Bridge (east of Stockport) last weekend, after being rained off heavily on two previous vists. More extensive than I thought and hard work on a bike, as it is on the edge of a steep hill.

The canal basin at Buxworth is interesting: where the transshipment used to happen between the tramway (now a cycleway) leading up to the stone quarries up in the hills and the Peak Forest Canal.

A nice day to be out on a bike yesterday, so completed a lot - the parishes of Comberton (a medium sized village) and Harlton, Great and Little Eversden, Kingston and Toft (all quite small).

Completed the long-outstanding village of Bar Hill, near Cambridge, a dormitory overflow settlement built in the 1970's. Also discovered a link through to Lolworth which is otherwise inaccessible by bike as the only road is off the A14 which is a motorway in all but name. Introduced a new mapper to the project, we started off together doing Bar Hill.

On holiday in Ireland between Carrick-on-Shannon and Upper Erne on a boat on the canal. So mapped the canal of course. A bit short on names because they don't have street names inquite the same way as towns, and I wasn't concentrating on mapping either.

A pleasant ride in nice weather completing the villages Whittlesford, Duxford, Ickleton and Hinxton, including the Human Genome Campus. The A1301/M11 junction was completely wrong - there's two separate roundabouts, not a single roundabout with grade separated junction.

After a puncturedisaster last time, a more successful visit this occasion on a glorious summer Sunday afternoon. Completed the large village of Sawston, plus missing detail for the small village of Pampisford, which completes that. And the streets either side of Whittlesford station before catching the train back from there.

Friday afternoon completed surey of Meldreth and Melbourn, which means Cambridge is now completely linked to the Hertfordshre border and everything off the A10 between Cambridge and Royston is done.

Curiosities included a complete but shattered bell in Melbourn Science park; some gorgeous marrows for sale by the road side, and a little driveway with a notice "Tea Ladies Only"

About a third (the north-east quadrant) of the large village of Sawston south east of Cambridge completed today. Would have done more but I had yet another puncture. Every time I go out something seems to go wrong with my bike.Last week it was a broken saddle. So more of Sawston to follow another day.

Two sessions this week comprehensively surveying a group of villages off the A10 SW of Cambridge: Harston, Newton, Haslingfield, Hauxton, Barton, Foxton, Shepreth, Barrington, Fowlmere and Thriplow.These bring us much closer now to the Hertfordshire border, with only really Melbourn in between.

The A428 road between Cambridge and Bedford has been dualled as far as Caxton Gibbet (where it meets the A1198 between Royston and Huntingdon). The old road has been declassified and rerouted in several places.

I mapped all this on July 20. Also the village of Hardwick, west of Cambridge, and the northern half of the new town of Cambourne a few miles further west; there's still quite a bit to do there. Also enabled me to link up Scotland Road at Dry Drayton with Hardwick.

Now I've discovered there is a diary...

June 9th, cycled out to Balsham (already mapped) and then over to Linton via Chilford Hall vineyard. Linton village fete underway. Mapped the whole village (about 4,500 people) in about three hours, and then just finished off the small village of Hildersham up the road.
