I try to put it on everything I map. It shows fellow mappers how accurate my contribution is. They can make a more intelligent decision about whether to change it according to their own sources of information. source=survey "I went there. I took pictures/made notes. The tags and geometry are correct. Ways were made with GPS tracks, they should be good but may have artifacts." (I should really use the gps tag as well, but I am lazy) source=yahoo_imagery source=Yahoo "I traced this from Yahoo imagery. Details are not easy to see so things like road intersections should be checked." source=npe (UK) "I traced this from an old map. Relative position of the feature should be accurate but absolute location may not be accurate. The feature may have changed or gone." source=npe;local_knowledge "I traced this from a map. I know the feature is still there and that my tags are correct." source=landsat "Hey, if you can get a better source, please change." source=interpolation "I went there but guessed the outline (buildings, sports pitches, ...)"
