Re: [OSM-newbies] How to tag when building present
On Sat, Dec 20, 2014 at 7:31 AM, Gavin Scott gavincsc...@gmail.com wrote: In my area all the buildings have been drawn. How do I tag the facilities located in those buildings? Here are the options Create a point inside the polygon and tag that with the attributes of the fasciities/functions that operate within the building, say Hopsital, or Shop. Tag one of the nodes that form the building polygon with the services performed within. Perhaps one of the the entrance nodes. Tag the polygon line. (I think this is impossible as the line has already been tagged with the value building. This is perfectly possible. You cannot tag _the same key_ twice, but you can have different ones. building=yes + shop=bakery is perfectly valid. I should point out that all of these building polygons has been tagged with key=building If you mean by this what is usually meant by it, we have a major retagging to do. The way to tag a building is not key=building, but building=yes To get back at your question: I would be against the second solution (using one of the nodes of the polygon. The polygon, if everything is correct, should denote the outer walls of the building. Only things that are actually on that outer wall should get mapped on nodes of that polygon. A shop would be extending into the building, so putting it on the outer wall would be incorrect. Putting it on the polygon would be correct if the shop and the building are indeed 'the same thing'. That is, there is not something else in another part of the building. Putting it on a node would always be correct (unless it is already put correctly on the polygon). My preference is not to put it at the entrance, but at the (approximate) center of the actual shopping area. Another question. If one of these buildings conducts more than one function, say a bottleshop that also operates as a supermarket. these tags must appear on different nodes? One node one value I believe is the principal. It depends on what you mean by 'also operates as'. If it is really more like two shops in the same building, then put two nodes in. If it is one shop with a somewhat odd combination of articles for sale, choose one as the main one (a supermarket that has an extraordinarily large bread section is still a supermarket, a place where bread is baked and sold that also has a few shelves of other foodstuff is still a bakery). If you really cannot choose, use the semicolon as described in another answer, or consider it two separate shops and use two nodes. -- André Engels, andreeng...@gmail.com ___ newbies mailing list newbies@openstreetmap.org https://lists.openstreetmap.org/listinfo/newbies
Re: [OSM-newbies] Systematic shift between streets and aerial photo
Both can be the case, but here it seems it's the streets that are correct, the photograph that is shifted - When I look at nearby http://cycleland.blogspot.nl/2014/05/different-modes-different-priorities.html and then load the GPS traces (in Potlatch), there are several traces, and all of them correspond to the openstreetmap data, not to the satellite image.

At one point we knew very well, from the paper map we had with us and the GPS unit's breadcrumbs, that the designated trail was sending us to a junction 1km due north, only to then track back another 1km due south to a position roughly 300m to our east. As we were already nearing the end of the day and were tired, the prospect of saving ~2km of walking was too good to pass on, so we did the naughty thing and took a shortcut through the forest. I mapped it for two reasons: 1. If someone happens to be there and needs to get out of the mountain quickly, this is the best way to do it. 2. Now the mapped way is circular, otherwise it would have abruptly ended in the forest nothingness. The right kink shown at http://osm.org/go/Zc93G@e0M- (if it's not live yet, you should be able to see it by clicking the + on the map and then the data overlay) captures my dilemma. Following the marked trail we would have walked on due NW back to the guidepost, and rejoined the Long Path. I currently chose to: 1. break the way in two 2. clearly mark the shortcut section as such (by name) 3. not using the foot=designated tag for the shortcut. What's the right thing to do in a case like this? This is useful data for the map in case of emergency, but I don't want this to turn into a mainstream trail either! I would have mapped it with no name at all, and with highway=path rather than highway=footway.

Best would be to have a list of all traces, on which one could select which ones to include and which ones not, but it would also be a great improvement to be able to only see traces from a certain time frame. -- André Engels, andreeng...@gmail.com ___ newbies mailing list newbies@openstreetmap.org http://lists.openstreetmap.org/listinfo/newbies

It seems that the proper thing to do is simply join the unnamed part to the named part, but I cannot figure out how to do that. The Potlatch cheat sheet says something about Join/Merge to another line (if they share an end point) by Shift/click, but nothing particularly useful happens when I do that. Start as if you simply want to extend the way, and move in such a way that the other way is highlighted (so that there would be a common point created if you would click). Then move (back) to the common point and press shift+click. I myself find it easier to first remove the common point from one of the ways, then re-add it in that way. Still, I have to wonder whether merging the ways is the right way to go here: there is a lot of TIGER-data, and I am not 100% sure all of that data applies to both parts of the way.

Maybe it's like trying to determine if the light stays on in the fridge. Seriously, you have got to be joking. There is no way in the world that I am going to make millions of areas to describe each little bit of a residential area that sits between each road, building, etc... every time you want to add another element to the map, you'll have to go back and cut a hole in the existing area in order to place the new element. I think cutting holes in area elements is more of a mistake than layering. I think that cutting holes will not be necessary. Rules inside the renderer would be a much better way to do this - if area A is completely inside area B, then render the area as area A, or more general, if something is a part of two areas, render it as the smallest. Unfortunately it seems the actual renderers seem to have taken a different route, where in some cases the overlapping area gets a kind of mixed colour, and in other cases some type of area always takes precedence over another, even if it is a part of it, but I still think that a rule as specified above would be the best way to go. -- André Engels, andreeng...@gmail.com ___ newbies mailing list newbies@openstreetmap.org http://lists.openstreetmap.org/listinfo/newbies

I will answer your questions in reverse order: And third, is it appropriate to add a nearly zero-length cycle path to show that bikes and pedestrians can go through, or is there a better way? It is not just appropriate, I consider it compulsory. Although I do think that for cases like this pedestrian (with bicycle = yes) is better than cycleway.

The bollard should be placed at the spot where the residential road changes into a pedestrian road, or somewhere on that pedestrian road.

The addition of the pedestrian road might already solve this, and we also tag for the database, not the renderer.

I disagree. I think standard speed limits can also be useful to include, for several reasons: * to denote to other volunteers whether someone has bothered checking the speed limit already so that when five people are checking speed limits in the same region, they are not all checking the same roads * because default speed limits vary by jurisdiction * because people may differ in the way they map their regional highway types onto the ones of Openstreetmap, so that two roads may both have the default speed limit for their type of road, and have the same classification, and yet have different speed limits * because speed limits on the same type of road may differ - in particular they are often lower in cities and towns than on the countryside -- André Engels, andreeng...@gmail.com ___ newbies mailing list newbies@openstreetmap.org http://lists.openstreetmap.org/listinfo/newbies
Re: [OSM-newbies] highway shapefiles - how to translate road types?

I now have them (thanks!) and am working on interpreting the highway (contains all roads) shapefile. Below is the list of road-types contained in the shapefiles (18 different categories in all). Where can I find information that defines what all of these terms mean? Specifically, I just need to know which roads can be driven on, and which cannot. Here are my ideas about what the various roads mean. Specific tags about car accessibility (access = ..., motorcar = ...) always trump the highway tag. I'll change the order some to get the major groups together and in order 'Normal' roads, from highest to lowest grade: 'motorway' Minimum two lanes per direction, separate lanes for the directions, all crossings uneven, highest maximum speed, part of a national numbering scheme. 'trunk' Connections with other roads are usually uneven; slow traffic (bicycles, tractors) are not allowed; often but not always separated lanes; part of a national numbering scheme 'primary' Major connecting road between towns or between a city and the rest of the world. Minor roads and single houses usually don't connect to it. 'secondary' Connecting road between towns or between a city and the rest of the world. When connected to other roads it has priority. 'tertiary' Any road that is not 'big' enough to be secondary, but is still used for interlocal or (in cities) interquarter traffic. 'residential' A road inside a village, town or city, the primary purpose of which is to connect houses to the road net. 'unclassified' The equivalent of a residential road outside urban areas (although here in the Netherlands because of the way the AND-data were imported, most residential roads are actually specified as unclassified as well) 'service' Anything that looks like a road, but that one would not necessarily expect to have its own road name. Usually can be driven on. I myself mostly use it for entrances to parking lots and similar. 'track' An unsurfaced road, usually broad enough to drive a car (otherwise I would classify it a path), but whether it can actually be driven depends on the road surface and the type of car. Links: 'motorway_link' A piece of road connecting a motorway to another road 'trunk_link' Connection between a trunk road and another road, the other road not being a highway 'primary_link' Connection between a primary road and another road, the other road not being a highway or trunk road. 'secondary_link' Connection between a secondary road and another road, the other road not being a highway, trunk or primary road. Pedestrian roads: 'pedestrian' A road inside a city, closed off for most traffic to allow use by pedestrians. Driving on it would be possible if somehow you got on, but it is not allowed. 'footway' A road or surfaced path specifically designed to walk on. Driving on it is not allowed, and usually not possible. 'path' Anything used to walk or drive on that is not built or maintained as a road. In most cases an unsurfaced walking path. Not suitable to car traffic. Others: 'Driveway' I don't think this one is standard 'road' The type of road is unknown to the person who entered it into OSM -- André Engels, andreeng...@gmail.com ___ newbies mailing list newbies@openstreetmap.org http://lists.openstreetmap.org/listinfo/newbies
