Sorry but this is missing the point ... There are many specialist areas, and some good lists that already support them, but the whole point here is not a single niche subject, but rather elements that are currently mapped but evolve over time retaining many elements visible on the ground but with gaps created due to new development, or changes in layout as bottlenecks are improved. We are not talking about mapping historic details from maps but simply retaining currently mapped data in a slightly different format so that the information can still be accessed. Railways are just a small but easy to identify element that have become uneconomic over time. As have some waterways, and coastal erosion continues to affect some areas of the UK, and I'm sure the rest of the world. All are slowly evolving ove time and that evolution is as useful as a map that only displays a snapshot of 'today'. HOT is mapping disaster areas and the the currently mapped details get overlaid with the effects of change and the remaining visible elements stick through. Trying to cherry pick what gets kicked to an 'historic' database and what remains in the main one should not be necessary especially if the restoration work slowly returns the original elements. Simply tagging collapsed buildings or blocked roads and railways and then tagging what gets rebuilt and what replaced is exactly the sort of data that should be recorded. -- 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
