Value of OSM
From OpenStreetMap Wiki
Page for estimating the financial value of OSM data, or the cost of producing it, based on a mailing list thread in June
Considering it is estimated to take 1-2 days for mapping a medium-sized town, it should be possible to map somewhere in a weekend (see Weekend mapping projects)

Speed of surveying, estimates
| Method | Surveying time | Editing time |
|---|---|---|
| Roads, by car | ||
| Country roads, by bike | ||
| Towns and villages, by bike | Approx 1-2 days for medium-sized town (like Sandy, which is about 40% complete after an afternoon's (5 hours) cycling)
Waddington took 6-7 hours (over 5 days) 2.5 hours/85 roads Wellingborough Shipston-on-Stour - population approx. 4,500 - 3 hours to survey on cycle |
About 2-3 hours per town or village, including all road names and designations
|
| Cities, by bike | 1 hour per 15 miles of street?
150 hours for 100,000 population, outer suburbs of London |
1 hour of editing per hour of tracklog recording |
| Cities, by foot | 1 hour per 3 miles of street? | |
| London streets, using eCourier data | n/a (but thanks to the couriers!) | |
| Bridleways and cycle routes | 1 hour per 15 miles? | 0.5 hours per 30 miles of cycleway or footpath? |
| Footpaths | 1 hour per 3 miles + travel time to reach the footpaths | |
| Rivers, by satellite photo | n/a | Ojw did about 40 miles of the Thames in about 4 hours. Most of that time was waiting for data-transfer |
Estimates of OSM size
| Feature | Approx. number in OSM database | Estimation method |
|---|---|---|
| Towns | at least 11 towns in the UK, plus 17 villages near Bedford | from PDF atlas/places.txt |
| Cities | at least 20 in the UK | from PDF atlas/places.txt |
| Roads | 34,000 miles | Planet.osm from may, including untagged segments assumed to be roads, but excluding things tagged as railways and paths |
| Bridleways and cycleways | ||
| Footpaths | 500 miles | Planet.osm from May |
| Railways | 500 miles | Planet.osm from May |
