Re: [Talk-GB] NPE data

2013-10-07 Thread Tim Waters
I think this shows one of the benefits of adding source tags to our edits
 - because in the future a better source may come along.

At the time a lot of natural features in the UK were traced from NPE maps
and they made many parts of the UK in OSM much better than nothing.

It's really encouraging, and we should further encourage folks to re-map
and edit areas.  When I encounter something tagged with NPE as the source,
I feel more confident moving and editing it whether aligning a stream to
Bing imagery or to my GPS trace we'd also need to remind people to
change the source tag as well!

Cheers and happy mapping!

Tim

For a while it was the best we had. But that was some time ago. (2008?)

 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.

It should be deleted then.

 would just remove it!!! But is there is a process to get it removed?

You select it in the editor and hit delete.

Or more appropriately, rather than deleting the whole stream you may just need 
to remove the offending section. You can do this by following it to the 
point(s) which join up with modern reality, splitting the way there and then 
deleting the appropriate section.

 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?

It may take a few hours for the tiles to re-render without the stream and even 
then you may have the old ones in your browser cache.

Of cause it would be nice if people could actually tag when a feature ceased to 
exist using the end_date tag. This is all important material for the OHM view of 
history.

Re: [Talk-GB] NPE data

2013-10-06 Thread SK53
In general waterways mapped with NPE will be rather inaccurate. It is more
likely that this stream still exists but is perhaps as much has 200 metres
away. Masses of persistent features (notably streams, but also major roads
etc) were mapped from NPE maps upto around 2010 when OS OpenData and Bing
maps became available. There has been no concerted effort to revise this
data: perhaps there should be now!
