Looking for something to map?
I'm not an expert at anything & understand mistakes as I have made my share of them - this could make it easy to work with me? I'll point out where I think you may have made an error, but don't see the sense in the blame word - mistakes will happen with the quantity of data we process. We just have to put them right later. I'm more than happy to work with someone else in adding detail to the map. I like surveying, and try to have a good walk or cycle ride most days. I've mapped Swanley right down to building detail for the majority of the town, but in quite a large area I have added a node with an address number, but it needs the rest of the information added, and preferably the outline of the building added & the tags adding to either the building or the entrance. There are currently address nodes in Lullingstone Avenue, New Road, Woodlands Rise & Woodlands Close + I will be adding more if I get time (To see them you have to zoom in at a lower level than that at which the buildings are visible).
If you're interested in working with me, read on about how I obtain my data, and how I add it to the map, then contact me with your suggestion as to how we could work together.
I use several methods for obtaining data, probably not always the most appropriate, but I try!
When I cycle I normally have my garmin gps turned on obtaining tracks - this seems to produce the most accurate of the traces I have produced over the years. The map on my garmin is obtained from Talkytoaster. I also obtain traces from my android phone using OSMTracker. In the past I've used various methods of obtaining traces - even if they are not particulary accurate, provided you have set the recording rate to 1 per second, by the time you have 6 traces of a road or feature, you will be able to see where the average of the traces is.
I try to visit most places at least twice - my phone is Android at the moment, and I use OSMTracker with a custom layout to make it easier to collect info about speed limits, lane numbers, traffic calming, & lighting. On this initial visit I try to get shop details, bus stop details (updating Naptan data), speed cameras & post boxes. (I currently use OSMand as a navigation programme on the phone as an incentive to get the data right!).
My second visit will be a long time later, and will involve a foot survey using KeyPadmapper3. I walk fairly slowly gathering house numbers, doing one or two streets at a time before I save the file & start a new one (if there is an IT hitch I haven't lost too much this way). KayPadMapper3 produces an .osm file, and a .gpx file for each mapped area, and I load this into JOSM, download .gpx traces to align everything to, then load BING or similar aerial imagarey & align the address nodes to the centre of the building they refer to, before uploading to OSM. The nodes may sit in this state for days, weeks or months before I do more with them.
Final editing (nothing's final!)
I use josm with the buildings, terracer & address plugins but that's just personal preference built up over the years. I've tried the built in editors & Potlatch 2, both of which produce excellent results. Each building node needs a city & street tag at least, and they may get this as an interim stage or I may move straight to building tracing then copy & paste the tags across. If I know where the entrance to the building is, the address tags should be pasted across to here & removed from the building outline, but this hasn't always happened in the past (I said earlier I make mistakes).
Every couple of months I visit Matt Williams excellent postcode finder website (http://milliams.dev.openstreetmap.org/postcodefinder/landregistry/) and enter a partial postcode such as 'BR8 7' and update any buildings or nodes for which postcode data is now availalble.
Working in partnership
If you would like to update areas I have surveyed, you would be very welcome. I'm also willing to try surveying areas for other mappers, provided you are not asking for somewhere too far away to be surveyed (I can cycle to places about 10 or 15 miles from Swanley for surveying purposes, and may even be able to visit places further away on occassion).
