Re: [OSM-talk-be] Question about speed limit rules in Belgium

In the Netherlands the rule is that outside villages, a speedlimit is valid for a roadsection, which is until the next crossing or junction. Is it the same in Belgium, so if I don't see a speedlimit sign after a crossing, the speedlimit is not valid anymore? A speed limit signed with a traffic sign (e.g. C43), and without zonal application, is valid until the next junction.

Luc Van den Troost wrote: Perhaps you can explain how 'abandoned' and 'disused' SHOULD be interpreted in relation to the rendering rules. As far as I have seen, the wiki pages about railways do not mention this. I can only explain at the moment how these situations handled on the mapnik map. How they *should* be shown, is another matter. Opinions differ. Personally, I don't need to see a (former) railroad on the map, when the tracks are physically gone, especially if it's converted to a cycleway. If both should appear on the map, then probably 'historical tracks' that are no longer visible should not be mapped, or at least not this way. Currently, mapnik renders railway=disused/abandoned/construction all with the exact same style: a dotted line. Historical items then might be mapped in a different way that is usefull for, for instance, a separate rendering or different layer. That would not only be the case for historical railway tracks, but as well for historical city walls, canals, gates, old river quai and docks, ... that all have influenced city development. But that is another discussion. Hard to solve, unless *every* data user starts to understand and process something like date_start/date_end tags. Another 'historical' point is that it is a pitty that OSM doesn't offer a kind of 'time-machine'. On one side it would be nice to see the growth of OSM that way, on the other side the map we are currently making will be historical one day. If - for instance - Doel would be broken down for harbour expansion, going back in time then would show how it was before, same would be if the 'hedwigepolder' on the other side of the border would be flooded again. But again, that is just a side remark and another discussion. Don't forget the Prosperpolder, where works are already under way to open it to the Schelde. I fear the infrastructure needed to store, process and show OSM as it was in a particular point in time, is not easy to construct.

Re: [OSM-talk-be] data error? errors with osm2gml.xsl
For now I just remove this tag and process my data without it. For the Antwerpen status page I do not need it. Removing a tag just because a tool doesn't grok it, seems like the wrong thing to do. Unless you only removed it from your local data, of course, and not from the OSM db. There is nothing wrong with a tag named '3dshapes:ggmodelk' in OSM. The colon is used in various places in OSM tags, as a namespace delimiter. The tool needs to be fixed, not the data. By the way, I am the one that put it there. Be prepared for a lot more of these tags, near the NL border. See http://wiki.openstreetmap.org/wiki/3dShapes for more info. The /Details page also explains 3dshapes:ggmodelk, and what you can do with it if you encounter it. Basically, it's the value an object had in the original dataset. If you're sure that what's imported is right (for instance, really a house, really a forest, really water), there's no harm in deleting the key for that object. -- Lennard ___ Talk-be mailing list Talk-be@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-be
Re: [OSM-talk-be] Hi all
but I think the NGI won't even consider doing that. In the import It's certainly worth it to ask and explore this, before we turn all our attention to CLC2000. I also believe we should explore the Freedom of Information acts more. Especially the Federal Decree has some interesting sections on our being able to use official documentation released under FOI. But, being Dutch, if someone from Belgium could delve into this, that would be better, I think. One less barrier to scare the officials. :) section they describe how to do it. Do you all think it is worth it? I have the entire CLC2000 dataset on my server, and had a quick look. The answer is, obviously: yes and no. Con: The data is old, some things will simply be outdated. Pro: Some objects, like residential landuse areas, look pretty good. All the typically belgian 'linten' are very recognisable. Con: Other objects, like agricultural areas, are pretty large, and would certainly not form a single continuous area IRL. This would need extra checking after the import. Pro: landuse mapping in Belgium, outside where there is yahoo hires coverage and people have spent time tracing, is pretty lacking. Taking the specific things from CLC2000 that would work nicely would be a good step forward. Pro: the way the French have setup the Corine import is that you can exclude areas which are overlapping with existing OSM areas. You can then, later on, import those areas missed due to overlap, by hand, from a website. Ben said we could even delete existing OSM areas before the import starts, if we know the existing mapping is inaccurate. If you guys want, I could set up a map overlay with the raw CLC2000 data, so you can check it out? I have got some more plans, but I promise I want do any bulk uploads without consulting you ;-) Do you have any other potential datasets in mind? -- Lennard ___ Talk-be mailing list Talk-be@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-be

Re: [OSM-talk-be] Deinze: last call
One of my idea would be to do a detailed mapping of the foret de Soignes / Zonienwoud, and organize this with local associations that are interested in the promotion of the forest and education to ecologie. This could also be done in collaboration with scientists who could be interested in a better mapping of the forest for further analysis. Wht do you think about this ? I would not recommend mapping a forest, if you also want to cater for newcomers. Interpreting GPS tracks is hard enough when you just start, and working with GPS tracks from a forest with lots of tree cover requires experience to make the right decisions. However, if you have the right persons attending, and you are able to convey those caveats, it could be a fruitful day of mapping. If you do expect lots of newcomers, I would start with a residential area. -- Lennard ___ Talk-be mailing list Talk-be@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-be

The CORINE data is not that bad, but is slightly generalised in the sense that features smaller than 25 ha are not present, and are rolled up as part of a larger area. The way the import in France was done is to compare the CLC polygons to OSM polygons. Only CLC polygons with no overlap or a very small overlap to OSM polygons were automatically imported.

The 2006 dataset is not publicly available from the EEA and has to be obtained through the participating national agencies. We already received permission to use the CLC 2006 dataset in The Netherlands, but we then have to buy the actual dataset. The point is moot, since we already have the much more detailed 3dShapes data. We can still use CLC (2000) to enrich 3dShapes classifications. For Belgium, it's different, and any broad addition of land cover to OSM would mostly be welcomed, I assume. If it would be actually useful is another matter altogether. I think it would look nice on lower zoom levels, and could be useful as a starting point for individual mappers to improve upon, but more detailed data may already be available which would make a blanket import action undesirable.

Re: [OSM-talk-be] Problems with JOSM's unwanted behaviour.
But If you click on the last node of your way, then press Alt while adding the next node, then you end up with a new way that share its first node with the previous way. Exactly, and that was what he was told in the ticket. I entirely disagree with the suggestion to disable autocontinuation, and am very content with the way JOSM currently works in that respect. The example in the ticket (starting from a node in the middle of a way produces a continuation) is convoluted as well. It *doesn't* do a continuation of that way. That's also impossible in the data model. In the example (in the ticket) that node is also the endpoint of *another* way, and it does do a contination of *that*. However, it's made out to appear that selecting a non-endpoint node of a way and then drawing from that will produce a continuation. Not so. In short: use the modifier key when drawing a new way from an existing endpoint node. Don't go through all the hoopla of extending a way, then splitting it, deleting the tags, applying new tags. That only makes life difficult and indeed obfuscates the way history. -- Lennard ___ Talk-be mailing list Talk-be@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-be

However, it's made out to appear that selecting a non-endpoint node of a way and then drawing from that will produce a continuation. Not so. No, you didn't understand the examples. I never sayed that a road was boken up in the middle and then continued. It is just when you start a I was not saying that either. [...] This is exactly what happens when editing at node 803205990. This is exactly what I described. As most often, you intend to add a new road, the default behaviour should be like that. I think it comes down to being of another mindset. For me, clicking an end node to continue that way seems the natural thing to do. If it so happens that end node is part of a crossing, so be it. I have to remember to use ALT if I want to start a new way at the crossing. Of course, I could be entirely spoilt from having worked this way in JOSM for years. I thought Potlatch did the exact same thing. What is the handling in Merkaartor for this situation? (Count once your ways when editing and compare extended existing versus added new ways) That's not a fair comparison. Often enough when adding new ways, you are *not* at a junction with another way endpoint. You might be starting a new way in the middle of nowhere, or branching off of another way, but *not* at a junction. In my experience, when adding new ways, starting one at an 'endpoint junction' is the exception. The splitting and additional obfuscating happens, while this seems the obvious way for most users of getting out of this unexpected alongation. For some messy results see my examples Verstrekenstraat and Jachtdreef. I can actually agree with your other point, being that when splitting a way, the existing ID should stay with the longest fragment. You might modify your JOSM ticket to emphasize that part, or perhaps even better: start a new ticket with just that request (with a reference to the current ticket). -- Lennard ___ Talk-be mailing list Talk-be@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-be

Dat lijkt me ook logisch want als je bijvoorbeeld een landuse=cemetary of garages of zo hebt, dan wil je niet dat die onder de residential gerendered wordt. Die anderen zijn belangrijker dan de residential. En de residential onderbreken of een gat maken voor de andere landuses is compleet onnodig en zorgt voor veel overbodige data. Ik zie dat niet anders dan een layer toevoegen aan een tunnel of een brug. Daar wil je ook taggen voor de renderer zodat die goed rendert. Een grote landuse is veel overzichtelijker en handiger om mee te werken, in alle opzichten. In Nederland zijn de gebieden met landuse=residential al in een heel vroeg stadium geïmporteerd, in de tijd van de AND-import. Toen was het blijkbaar nodig, of de toenmalige renderers (bijv. osmarender) ondersteunden het niet, om met de hand de landuse te ordenen. Osmarender sorteerde bijvoorbeeld alles per layer en renderde dan de objecten in volgorde waarin ze in de .osm file stonden, dus met oplopende ID's. De huidige methodiek van renderers, in ieder geval die ik ken en gebaseerd zijn op mapnik en/of de standaard kaart op OSM.org, is om te sorteren van grootste oppervlakte naar kleinste (binnen een layer klasse). Als je het in die volgorde rendert, zal het grootste gebied (een bebouwde kom met landuse=residential) altijd onder kleinere gebieden (een grasveld, een kerkhof) komen. Het argument van layer=-1 voor landuse=residential heeft dus zijn oorsprong in het verre verleden. Met de huidige generatie renderers (en manieren om met data om te gaan) is het m.i. niet relevant meer. In NL had de uit de AND-tijd overblijvende landuse=residential allang ontdaan kunnen zijn van layer=-1. Als dat gedaan is, is er alleen indien de landuse=residential valt binnen een nóg groter vlak landuse (bijv. een bos) nog maar een probleem. Echter, daar hebben we tegenwoordig multipolygon's voor, waardoor we een gat kunnen maken in het grotere vlak. En ten slotte, we zouden ook weer kunnen terugkeren op een hele oude discussie, die van landuse als fysieke eigenschap vs. landuse als functie-omschrijving.

Robin Paulson wrote: while we're on the subject of convoluted tagging schemes for highways, i've always been intrigued by the following combinations, which seem to mean the same thing, but are clearly different: highway=footway cycle=yes highway=cycleway foot=yes is there any difference between these two? Yes, in the cases where I've used this way of tagging. The difference is in the signs used. The highway=footway;cycle=yes is mainly a footway and marked as such, but with a sub-sign saying 'cycling allowed'. This implies that the main users are pedestrians, and cyclists should take all due consideration to them, like not claiming the road. Cyclists are 'guests'. The other is actually the other way around. It's marked with a cyclists sign. You are allowed to walk on it (since there might not be a suitable footpath or sidewalk/pavement nearby), but have to realise there are (fast) cyclists around. Often, the foot=yes is implicit, because pedestrians can go pretty much anywhere, like on cycleways if no pavement is present or even the main road if neither is present (at least in The Netherlands and Belgium). I'm using an explicit foot=yes if the cycleway is not paired with a nearby pavement/footway, so the routers will know they can use it for pedestrians. Now, what I'm curious about, and what came up in recent discussions on talk-be and #osm-nl, is how far the implicit foot=yes goes in both OSM in general, and current routers specifically. Not every country has the same implicit access rules. For instance, in Belgium where a do-not-enter-for-drivers sign (round, white with red border) is used, with a sub-sign 'residents only', it is implicitly assumed that foot=yes (since pedestrians are not drivers, the sign does not apply to them), but also bicycle=yes;horse=yes, even though they're legally both drivers, and don't have to live on that street. Currently, I would need to tag every such destination-only road in Belgium with: access=destination;foot=yes;bicycle=yes;horse=yes. Would it be possible in the future to mark such implicit nation-wide access=* rules for various types of road? So within Belgium, I could get away with the much easier access=destination and be done with it, unless there are explicit *=no access classes) ? -- Lennard ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

It apparently never was a real problem in law enforcement, or it would've likely been amended. explicit speedlimits here as well, but Lennard was writing about implicit speedlimits (in town=50 and the like). Those are not valid for bicycles, but this is IMHO also not a very important issue, as most bikers don't get beyond 50km/h. Exactly, it's a moot point, and I included it mostly to make the point that there are so many subtle ways to handle maxspeed, that it would be difficult to make an all-encompassing tagging scheme.

My thoughts are that the import process should sort out the hard part of this: comparing of features against a polygon, and stamping them with a field we can filter on in mapnik.

Re: [OSM-talk] Patch to render names from routes and custom highway shields on a per country basis
John Smith wrote: This is already dealt with for coast lines, so it shouldn't be much of a jump to deal with country borders in a similar way. Indeed, but a factor to take into account. Only update your internal version of the boundary when a newer and valid version is in OSM. At present we're using multiple relations where the name changes along a route but the ref stays the same and vice versa so it's not possible with the current pre-processing that is done to do a nice little query to get the shield and name from the same query. I have no idea how to fix this. If those relations get flattened into a planet_osm_line geometry, you have 2 (or more?) for the same stretch of road. One for the shields, another for the name. Join them up in a query, or split shields and names handling everywhere and take what you need from the relevant geometries. The other biggy is dealing with the country borders during pre-processing, again no idea how to do this. You'd have to supply osm2pgsql with the relevant borders right off the bat, before it starts importing. That would mean 2 runs over the planet file (ouch!), or publishing a separate file with the relevant data. That is if you let osm2pgsql do the processing. As with coastlines, the country/state boundaries don't change drastically in the course of weeks, so an updated version of the regions could be generated every once in a while. OTOH, if osm2pgsql will only run some queries and let postgis handle the stamping of features with a proper field to filter on in the stylesheet, it can be done at the end of the import. The challenge to this method is in how to handle diffs. You wouldn't want to run through every geometry in your database everytime you import diffs, but only the changed ones. One more issue I see is what to do with features that cross these boundaries? Which style will/should they get?

Split the border-crossing road twice, so there is only a short section that actually crosses the border; probably less than 10 meters.

Names change, refs change, maxspeed, surface, etc. We're already breaking it up for any number of reasons, at a border.

One of the reasons being that if something happens there, you don't have to explain emergency services where you came from and where you were going, but can just tell them the ref on the nearest marker. Say where the motorway has ref=A16, the motorway_link may be numbered ref=A16f. In Belgium, they can have refs too, but they seem to be a longer (internal?) version of the numbering scheme.

Do other countries have speed limit signs on every way? That's not how I remember it from my brief visits to the USA and Crete (other holidays didn’t involve driving). Commenting on the NL situation: there are default speed limits for road classifications and where they are (inside or outside built-up areas). These can be overruled with posted speed signs, which only apply until a junction (motorway: on-ramp) in the road. After the junction (aptly called a 'decision moment' in pseudo-legalese) the sign has to be posted again if it differs from the road default. To overcome the multitude of signs, in many places they're now using a zonal application of posted speed signs, where the sign is the same, but it's framed on a rectangular sign with the word 'Zone' written above or under the speed sign. These apply until you've passed the 'end of zone' sign (with diagonal stripes). Only zone-30 is possible inside built-up zones (default: 50kph), and zone-60 outside (default: 80kph). Every other speed limit is posted with the regular signage regime. There have been cases where the zone was 'leaky' and you could enter it without having seen a sign. You'd have to document it fairly well if you got a ticket and wanted to legally challenge it, but that could succeed. The reason being: how could I have known, when I've encountered no signs? So, having a way to apply a speed limit to a broad range of roads (zones, built-up areas) and having a/various nation default(s) would be helpful. -- Lennard ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Re: [OSM-talk] POI by coordinates
Tom Hughes wrote: the situation is: I've got a POI in the area where I'm only in summer. I've marked in somewhere in Google Maps and now I want to mark it in OSM. [snip] ...but bear in mind that importing data which has been derived from Google Maps is not allowed anyway! Even when someone has been there, verified the POI, and used Google Maps only as a fancy kind of notepad, in lieu of jotting down the coordinates on a piece of paper ? Of course, I understand, if he has placed the POI in Google Maps by checking their map and positioning the node from memory, this would not be usable for OSM. -- Lennard ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] Proposed Relations
Frederik Ramm wrote: 2. I want relations to become ordered and will try to sneak this into API 0.6; there will be no noticeable change for any API client, just that it so happens that things are returned in the order you put them in, rather than in any order. There is one noticeable change here to clients: if they download such an ordered relation, and upload a newer version, they should have kept the ordering intact. The current unordered relations mean that a client can store it locally however it likes, and upload it in a completely different order, and it won't make one iota of difference to anyone. That assumption would become invalid. -- Lennard ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Re: [OSM-talk] When will the next mapnik coastline update be?
Peter Körner wrote: Yes, the processed_p is available from [1], where it is generated every now an then (manual step). Then, it has to be updated at the osm mapnik server, which, again, is a manual step. This is not entirely true. The Coastline Error Checker runs through all the coastlines every every* night, generating a processed_p shapefile, but this version is not used by the OSM mapnik map. The latter generates its own coastline shapefile every time the full planet is reloaded, which happens on an infrequent schedule. So there are at least two people involved that are not working in an planned time schedule (as nobody pays them for this, i think). Fortunately, the coastline doesn't change that often ;) More often than you may think, as existing OSM data is refined, or sand suppletion or depletion is performed, either by nature or by man. * When hypercube isn't down or otherwise slow, which is quite often these days. -- Lennard ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
