Hallo. Maybe covered=yes http://wiki.openstreetmap.org/wiki/Key:covered is what you are looking for? Yours Hubert Am 30. Dezember 2014 05:27:43 MEZ, schrieb johnw jo...@mac.com: I'm micromapping some public areas, in this case train stations. two questions: 1) there are large open concrete areas for pedestrians, but there are also covered walkways through them as well. http://www.openstreetmap.org/edit#map=19/36.38380/139.07281 I mapped the open sections as highway=pedestrian+area=yes, while I traced the covered walkways (that connect the bus shelters) and tagged it as building=roof highway=footway I'm not sure if I should just create single area of highway=pedestrian and put the building=roof over it or what. Also, the roof doesn't render as a building, but as a white pedestrian area. I think if it is tagged at building=roof, I should ask -carto to render it as a building, but it logically remains a footpath as well. I'm unsure of how to tag it all. I assume I have made a mistake mixing pedestrian and footway tags. 2) what is the best practices for tracing sidewalks? when following a sidewalk along a road, and you reach an intersection, does the footpath way cross the road via the sidewalk (continuing along the road, or does it turn the corner, following the sidewalk encompassing the block, and the sidewalks are separate ways ( rather than a node) that join disparate footpaths at the corners of the intersection? This is an intersection mapped with footpaths following the sidewalks around the block, with sidewalk ways connecting the corners at the intersection. http://www.openstreetmap.org/edit#map=20/36.42339/139.05830 I'm guessing for simplicity, the way follows the street through the intersections, but to map the sidewalk as a way would require segmentation of the ways anyways, so following the sidewalk around the corner seems to be a cleaner choice, especially with the heavy paint work here in Japan for sidewalks.

Re: [Tagging] Accuracy of survey
Hi Warin and all, I am not sure what you dislike in accuracy. Accuracy is how far the measured mean value is from the actual value ( http://en.wikipedia.org/wiki/Accuracy_and_precision). However we can start calling it a trueness, to follow the ISO definition. If you mean something else, please explain, and I believe it would deserve a page in OSM wiki. Now, I am talking about the absolute trueness. That is, how far a POI is according to the map from its actual position on the planet. No, I don't forget that the planet surface is moving relative to the GPS coordinates. Even more so, there are local surface movements, especially if the survey marker is located, say, on a bridge or close to an excavation site. It should be considered when defining this non-movable POIs. Taking into account the inherent precision of the survey marker position (they are designed to have a well-defined position), it does make sense to have OSM data for them defined better than for all usual elements. At the same time, if you are talking about common use, these POIs are of little interest to normal users. So their specific properties will not disturb anyone. However, some mappers may be in possession of the surveying tools allowing them to have better trueness than possible with a GPS, provided that they have some good reference points. Survey markers are designed just for that. For these mappers, the absolute location of the survey markers is important, and I see no reason to prevent them from having it in OSM. OSM renders distort road widths according to their classification .. that is normal mapping for road navigation. If you wanted air navigation then the actual road width would be better to render, with runways having more emphasis. True. However the underlying data is independent from how a specific renderer represents each element. A street is usually just a line, thus having no width.

However we need a clear consensus on how we define the sufficient accuracy and how the data for such points will be updated. Ultimate 'accuracy'? You do realise that the tectonic plates are moving? So your reference points need to include a date so they can be corrected for the drift. You'll find that data is available for those survey reference points .. together with their precision. Do you want to update these points to maintain their 'accuracy'? How often? Survey reference points are 'quite common' in built up areas ... but not in remote locations. And depending an the age and how precise the survey was will have some effect on their 'accuracy'. One surveor in Australia forget to allow for the temperature effect on this measurement chain back when chains were used. I disagree with the point of view that an accuracy sufficient for consumer GPS devices is sufficient for OSM and therefore there is no problem here. Nobody ever declared that OSM is for smartphone users. We are trying to map the world, and accuracy should be of primary interest for this project. Again the word 'accuracy'. Context 1. I have advised one mapper in their diary that most, if not all, users will be using their data entry with similar equipment to what they have .. so any 'inaccuracy' will also be present for the other users. Thus what they map should represent what is there and should be usable as a map .. considering that the GPS information may be very vague under the tree cover present and the local cliffs etc. Context 2 I will be mapping a track that is covered in a few places .. by an over hanging cliff. As such it is not visible by satellite .. nor will the GPS track be that 'accurate'. So I'll be mapping it from the available information that I have then - a few photos, my track and the satellite image. It will take me about a week to traverse the area. No shops etc. I would rather have the less 'accurate' representation of what is there compared to a blank area.

Re: [Tagging] Accuracy of survey
2014-12-24 0:21 GMT+01:00 Friedrich Volkmann b...@volki.at: I used estimated_accuracy=* or gps_accuracy=* a couple of times, but I doubt that it prevents other mappers from moving or even deleting them. Some use editors like Potlatch, so they are not aware of tags. Some do thousands of edits, all of which are validator based corrections. They do not ask nor think nor look at tags, except at those reported by the validator. the effects of those semi-mass-edits or other careless following edits must not be feared too much: as long as the original tag is preserved (otherwise it will unlikely be noticed unless it is searched for) other mappers might take a look and see from the history to which coordinates the note belongs. I think notes are a good way of passing particular information about the survey conditions to other mappers. Positional accuracy should not be overestimated, in dense areas it is more important to have good relative positioning (things should relate in the map like they do in the real world, e.g. with regard to left or right side of the road, crossing in the same point or 2 adjacent crossings, angles, line of sight, size relations, parallel vs. not, etc. In these settings you typically won't find a GPS of much use when mapping today in a well mapped urban area. In lower density areas (e.g. countryside, mountain areas) it usually doesn't matter to have cm-precision, 10-15m are more than sufficient, bare some potentially very rare counter examples. Still I can understand that when you use equipment with significant higher or lower precision than average you'd want to have a dedicated tag to formalize entering the presumed precision in a machine readable way. just do it ;-) Cheers, Martin ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
