Re: [talk-au] Way has been simplified...
Thanks all, I will probably have a look at OSMAnd settings as a first step. When editing the note don't bother me too much.

Is it maybe really old import before changesets were added? I would delete such notes and have changeset with "original way geometry was simplified some time ago, unnecessary nodes were deleted" ___ Talk-au mailing list Talk-au@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-au

OSM data is ODBL and you cannot add data on incompatible licences. And anyway, full history us available anyway. ___ Talk-au mailing list Talk-au@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-au

Does anyone know what this means It indicates that the number of points in the lines has been reduced by removing the unnecessary ones, while keeping the simplified line within 3 m of the original. , why do we need the note?

Re: [talk-au] Way has been simplified...
By default OSMAnd shows things which may be of interest to mappers. If you don't want to see these notes, you can turn the feature off.

Does anyone know what this means, why do we need the note? What purpose does it serve? This is usually from an import of data. The data may have many points (nodes in OSM) that lead to data bloat. JOSM has a tool that reduces the number of nodes such that any error will be less than 3 meters from the original information, 'simplify way'. It may be better to have these as 'comment=*' rather than 'note=*'? They should only be for other mappers to see if they have some concern with the data. ___ Talk-au mailing list Talk-au@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-au

When using OSMAnd for routing I came across the following note: "way has been simplified using a error criteria of 3m" it is usually in green text. Does anyone know what this means, why do we need the note? What purpose does it serve?___ Talk-au mailing list Talk-au@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-au
