Re: [Tagging] Best way of tagging split between electronic toll and cash lanes?

I would use _link only, if it really links between two different ways, maybe even of the same type. But here I think it is just one highway going through, so I would not tag it as link. The toll point itself has to be considered as a slow down - essentially and visually by the user and supportively by a router. Using _link for the non-electronic lane may irritate 'normal' routers to prefer the electronic toll lane - and that may lead a non-electronic user in a dead-end. (downward compatibility as a security fall back) In this case the router should discriminate the lanes only by access tags (see below) - but not by the highway tag itself. Name, ref and relation - as you may choose every lane to go on your (high)way, all of them belong to all lanes in my opinion. There's also a question of what access restrictions go on the high-speed lanes. OK, to choose the 'right' lane by routers, it is essentially to know - but to use them, you need special equipment, and I don't know, if that is different for different toll passages. (Or is EPASS an 'everywhere equipment/operator'?) If you need different equipment, this (or the operator) must be tagged - and must be configured for the router too! I do not know, if an access=electronic_toll (with a subkey electronic_toll=*) would be satisfactory. (How do/shall routers handle unknown access values? I hope/think as 'no'). Nevertheless - as long as a router cannot discriminate _all_ of the necessary informations, he can only warn about the toll point itself - and the user have to discriminate visually.

Re: [Tagging] Feature Proposal - RFC - playground:splash_pad
Sounds good to me. I'd rather a clearly defined, unambiguous, possibly American term like "splash pad" than a less clear, but "more British" term like "water play area".

[Tagging] Best way of tagging split between electronic toll and cash lanes?
Many toll plazas now have high-speed electronic toll lanes. Tagging seems haphazard. As I see it, the choices are: *What gets tagged as motorway vs. motorway_link? *What gets the name, ref, and relation membership? Note that some plazas have the cash lanes marked like an exit: http://en.wikipedia.org/wiki/File:SR_417_University_Toll_Plaza.jpg while others have the cash lanes in the middle and the high-speed lanes as an exit. There may also be some where it's more of an equal split, with neither marked as the main route. So the question is whether to use motorway_link for what's signed as an exit, or to consistently use motorway for either cash or for high-speed. There's also a question of what access restrictions go on the high-speed lanes. ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

"German English" - the variety with with the allruntogetherwords? :) I'm a native en_GB speaker, and "splash pad" sounds unambiguous to me and not particularly an Americanism. "Water play area" sounds ambiguous and like it's a more widely scoped thing.

Numbering can be managed via the ref tag, postfixed with something like :nswssm to indicate that this reference id is for SCIMS State Survey Mark number. e.g. ref:nswssm=35225 > SCIMS lists 7 names for types of survey points.

I saw those 7 SCIMS names from http://www.lpma.nsw.gov.au/survey_and_maps/scims_online/glossary They seem universal and easily applicable to other states and other countries. So for now I'm using this same terminology for my tagging. > Any marks on the ground for positioning aerial photography (or > other remote sensing) would be a Mapping Control Point.

Two features I've encountered which would fall under this category, but I thing should be tagged differently are white pegs, and small metal disks with a nail or something in the centre which have "STATE SURVEY MARK" engraved... How would these two fall into SCIMS? They may both be CR's, but I think they need different tags as they are different. I would have thought the peg would be a CR and the nail an SS since the nail says "STATE SURVEY MARK"... > Trigonometric Stations are generally older then Cadastral > Reference Marks, and are known more accurately.

Re: [Tagging] Feature Proposal - RFC - playground:splash_pad
Not 100% sure about the history of using british_english for tags, but its linked to the project being founded in the UK and using british_english. To keep things simple the convention is, where possible, to stick with british_english for tags. Wikipedia has a use for some people, but openstreetmap is not part of wikipedia.The english pages are also dominated by american english which makes things difficult when using for researching openstreetmap tags. I suggested water_play_area because there is a successful "water play area" near me (I'm in the UK), and in recent years more parks near me have built these features and named them "water play areas". But googling around a bit shows that "water play area" has become confused in the UK. Although clear originally intended as an area with no standing water, it now seems some UK local authorities are using the term for areas of parks set aside for children to play with water. This area could have paddling pool or "splash park", or often both. So after all that I've changed my mind. It's better to use a term has a clear definition and it appears the north american "splash pad" only refers to areas with no standing water. It would be helpful to create a wiki link in Openstreetmap that directed "water play area" to "splash pad".
