Paul, NPE maps were the first backgrounds for the editors other than some quite low res Yahoo imagery of the UK, so people used them for mapping streams/rivers/woods etc back in the day. As you have noticed, they don’t necessarily relate to modern streams – they may have dried up or been culverted/piped long since. They are all over 50 years old, (for copyright reasons) after all. Yes, if the facts on the ground have changed, then the stream needs to be moved, or removed. No process needed, just use an editor.
Note – only remove NPE tagged items if you know they have changed – don’t just do a mass-remove! (That’s in the unlikely event you were planning to write a bot to remove them all!)

Do you really need to print this email? From: Paul Churchley [mailto:p...@churchley.org] Sent: 06 October 2013 16:57 To: talk-gb@openstreetmap.org Subject: [Talk-GB] NPE data I have come across some data tagged as source=npe. I know what the NPE maps are but my question is a bit of a newbies one... why is NPE data mapped on OSM if it is so old? I have just mapped an area for a customer of mine and there is a stream mapped running right through the centre of his property. It is tagged source=npe. The stream is no longer there and hasn't been for the 20 or so years he has owned the property. The old stream is showing up on OSM rendered tiles. His properly is a caravan site and so it would be good if his property did not have a stream that no longer exists running through it as it suggests that it might flood... which it doesn't. What is the situation regarding npe data? Can it be removed? Obviously I would just remove it!!! But is there is a process to get it removed? If it is to be kept, then how can we get the OSM tiles rendered without it showing this old stream? I can see that some specialist tiles might want to show old data like this but I wouldn't have thought it appropriate that normal OSM tiles would need to show this old data would it? Any help would be appreciated.
