Re: [openrailwaymap] DE: Optimale Position von railway:switch-Nodes u.a. / EN: optimum position of railway:switch nodes etc.

P1. Proposals for the position of tags for single turnouts (abbreviation: ST; including both straight as well as curved ones): P1(a) Tip of the switch blade (i.e., the position where the route changes; might be also recognized by the point machine in aerial images) P1(b) Tip of the frog ("massif" part; can be approximated from the intersection of both inner rails) P1(c) another proposal? P2. Proposals for the position of tags for diamond crossings (abbreviation: DC): P2(a) Center of DC, i.e. intersection of both track centerlines P2(b) another proposal? P3. Proposals for tagging of complex switches: P3.1 Decompose them whenever applicable: - diamond crossing with ... slips: * single = 2x ST + 1x DC * double = 4x ST + 1x DC - three-way switch = 2x ST (solves also the route ambiguity problem in single slip case) P3.2 Tag those parts according to P1 and P2. _My favorite_ is: P1(a) + P2(a) + P3.1 + P3.2, which considers the position of turnouts and diamond crossing and clearly defines the drivable routes on them clearly.
