Since I live within quarter of a mile of a section of 'abandoned railway' which used to extend several miles south and still extends several miles north I have a perfect example of one which perhaps needs re-tagging. There are still bridges and cuttings and while it is still essentially 'private property' some sections have unofficial footpaths. The section south of Broadway now has a new track (where it was dual track originally) and a growing new station. There is an option to continue north which would allow the preserved line to reconnect with the existing main line. Given the problems the preserved line has had with land slippage and having to replace 100+ year old bridges it may never happen, but the route is protected currently but 'abandoned'. Now if rendering changes do I need to re-tag this 'dismantled' to maintain the current map, or is this another reason for abandoning the main map service and providing an alternative? While my point about the historic aspect has been dropped, this line is also a good example of the managing of current and historic material since the main route of the line is preserved, the goods yard at a local army base is now being built over with a new housing development, and while it currently exists on the ground it will slowly succumb to progress and I have no problem with the CURRENT view of the data only showing the elements that remain, the history is a documented fact which just needs a slightly different style of management. It's NOT actually been removed from the database since it is still fully documented in the change log, so all we are talking about is semantics and allowing a view of the data that can be rendered using the existing tools. -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
