Having spent months already on this easy problem, I don't see how our limited ressources are going to solve this if we don't tackle the problem in a very different way. A first step might be to disallow upload of certain easily detected errors (e.g. self intersecting version=1 ways with coastline tags) either in the editor(s) or in the API. This is certainly not going to magically fix all coastline problems but it will lessen the workload of the advanced mappers who try to fix coastline problems.

I suggested something similar some time ago - processing in tiles would allow partial updates of the valid areas and the invalid tiles would simply be left in the previous state. Given the dynamics of the errors in the OSM inspector this would probably not cause any of the tiles to get overly old due to persistent errors. This is however not trivial to implement, it would not produce full unsplit polygons (which are sometimes needed - not for normal rendering though) and it would occasionally lead to small artefacts at the tile boundaries when one tile is changed and the other tile is not. -- Christoph Hormann http://www.imagico.de/ ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk

Sounds good. This should also increase the chance that if you see an error in the OSMI it is not already fixed (which is very common at the moment and somewhat annoying of course). How sensitive is your system by the way in discarding a coastline as broken? Obviously any unfixable error in one of the four large continental coastlines will trigger it. Same for large islands like Greenland and New Guinea i suppose. But there probably is a limit. There have for example been many coastline errors in the Philippines recently due to recent mapping activity there but many on fairly small islands. -- Christoph Hormann http://www.imagico.de/ ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk

And thanks to you Paul for the data files in the first place. Also I wouldn't want the impression I'm the only one fixing coastline errors, so thanks to the rest of you as well. Just to be clear the error points layer is automatically updated from Paul's files. The other error layers require manual generation so may only get done once a day. Also due to the number of error points the map current won't display in some (maybe all) versions of IE, but is OK in Firefox Chrome. I can't be bothered to fix this, as the number of error points is falling daily, and so it won't be an issue in a while.

Steve What do the red dots mean? the red dots represent where there is a possibility of a gap in gap in the OSM coastline ways following the deletion of data which is happening this weekend. This gap could just be a few metres, or the dot could represent the start of a missing section of many 10's (or possibly 100's) of kilometres. In order for Mapnik to render coastline correctly there needs to be a continuos line of coastline ways around all landmasses. Any gaps in the coastline ways will lead to poor rendering. What can we do about this ? The missing sections in the coastline will need to be completed. There are various ways this can be done. In Australia there is the option of: tracing from Bing or AGRI. there is also the possibility of importing data. I did offer on the talk-au [1] list to re-import PGS data (relatively low quality), though I did ask whether it was better to delay and wait until someone had time to reimport ABS data If you are going to add in any coastline data please be aware that the direction it is drawn is very important.

Although it would be possible in the next few days to redraw some coastline using JOSM and store this off line ready to upload when the database comes back on line, my opinion is that it is better now to do nothing until the new database comes back on line in a few days. I am sure that Paul Norman will then regenerate the shapefiles from which the reds dots are derived, and the error maps will be updated to show actual positions where coastline ways are then missing .

This version respects odbl=clean. The shapefiles are in their normal place at http://pnorman.dev.openstreetmap.org/coastlines/ Included is a .osm file with all the error points. An overview can be found at http://maps.paulnorman.ca/coastlines2.png Detailed views: Great Lakes: http://maps.paulnorman.ca/coastlines-lakes2.png Europe: http://maps.paulnorman.ca/coastlines-europe2.png US West Coast: http://maps.paulnorman.ca/coastlines-west2.png Australia: http://maps.paulnorman.ca/coastlines-au2.png There are no significant multi-square flooded or dry areas. The following areas have significant number of error points: Pudget Sound in Washington State The mouth of the Columbia river in Washington The Eastern Australia coast The points indicated by the maps and by processedc_p files are where coastcheck encountered an error and had to guess where the coastline continues. These should generally represent transitions between ODbL clean and ODbL dirty sections of the coastline. Islands with no ODbL clean sections will not generate any error points. http://www.wightpaths.co.uk/coast/CT-only.php and http://suncobalt.homeip.net:82/coastline.php are two visualizations of errors but neither has yet updated to the new data. I hope to complete one more run of the ODbL-clean coastlines before the downtime. During the downtime I will be running a set of ODbL-clean and conventional coastlines (and a planet file). If diffs are available during the rebuild process I will be generating them then and reloading my database when the ODbL planet is published. Technical details: This new run takes into account odbl=clean. It may not correctly handle 1. Objects that are dirty via a changeset override 2. Objects that WTFE reported clean but are now dirty 3. Certain sequences of edits and tag additions that are not likely to occur frequently with coastlines and which require access to a full history database to evaluate The data is from 7 AM PST and the ODbL status is slightly more recent. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

So the problem seems not to be the coastline stuff but that there are tiles that haven't been re-rendered for half a year!? I updated the coastline shapefiles used by the mapnik layer last night. The previous update was about 4 weeks ago. If no one edits any data in an area after the coastline shapefiles are changed then it may be a long time before the tiles are rendered again to pick up the changes (as you are seeing here). Normally I force the zoom 0 - 12 tiles to re-render across the world each time I update the coastline shapefiles but it takes too long to do all zoom levels on each update. Back in January I ran a process to re-rendered all tiles last rendered prior to 1st Oct 2010 across the full 0-18 zoom range. This took a few weeks to complete and should have picked you older changes. I will consider running it again with a more recent cut-off point.

The machine has only 16 GB. Anybody know how much RAM the coastline checker needs? The first stage of the coastline checker tool chain is a modified copy of an old revision of osm2pgsql. It could be adapted for pbf, same as the current osm2pgsql. It does two passes over the data, that's why a simple pbf2osm pipe doesn't work. The rest of the tool chain works on the resulting interim files, and wouldn't need to be adapted for a pbf planet. 16GB should be plenty. Last year I could still do a complete coastline run with a 4GB server, and it probably needs less than that. -- Lennard ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] coastline in mapnik
A stupid but working workaround is to go through the .osm file with sed or something and rename coastline to something else before running osm2pgsql. And the more logical solution would be to find the single line in the osm2pgsql code that drops natural=coastline, adapt that, and recompile/reimport. Also remove the natural=coastline 'delete' keyword from default.style. You'll then have the raw natural=coastline ways in planet_osm_line, and you can create a mapnik rule for those. -- Lennard ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Re: [OSM-talk] Coastline missing in Lake Superior - in case anyonenotices...
If you are going to delete many miles of coastline data, are you then going to take the responsibility for re-entering this data afterwards, to at least the same level of accuracy as the current data? It seems to me that it would be better to tell your editor program not to display the coastline during your editing session. After all, there are likely to be some people who want to render the coastline, and they won't be able to do so if you have deleted the data. ---Original Email--- Subject :[OSM-talk] Coastline missing in Lake Superior - in case anyonenotices...

I'm actually joining them to the CanVec water corners... but it's probably creating a coastal hole, not really sure if the join is actually working. My plan is to finish loading all the coastal areas with the canvec data. Then joining the big body of water with a single relation, on the Canadian side. That will become the new coastal waters object, when finished. On the USA side I'll just join the existing coastal waters object across the USA/Canada boarder. I should have the entire lake finished by the end of the week... I hope.

Yes. And therefore the problem lies in the rendering rules, not the underlying data, that's why these should be modified, not the data. Actually I can think of no case where water should not be rendered above other nearby polygons. The only situations would be covered underground water bodies, which should be tagged with a layer-tag and probably some yet-to-come-underground-tag, so I think this issue can be solved. (Probably the suggestion to map the water explicitly above and tag it with natural water, tidal=yes is the best hack proposed till now, but of course remains unsatisfactory). You lose the fact that the basin itself is part of the park, but I'm not sure how important that is.

Initially I could not get any of it to render as park. Somehow I eventually dumbed into something that renders the wetland islands as park, but it required deleting the islands and retracing them--not sure why. Anyway, I don't want to have to retrace the mainland wetland coastline to do this, and I also need to connect that with the dry mainland section. The entire wetland mainland area in the view is part of the park, and I know from visits to the area where the northern boundaries for the dry areas are. Can someone advise how to do this? I've stayed away from doing any further work on the local coastline until I figure this out. coastline and park should be entirely separate conceptually. Tag it how it is, and if it doesn't render how you think it should look into the rendering rules. Contorting the tagging to make the current rendering incarnation work right seems like not a good plan.

It depends on the context. A closed loop tagged with a highway tag is just a closed highway. Roundabouts are often simple closed loops, but render as a ring not an area. There are exceptions of course (it wouldn't be OSM without them :-)) If you want to draw a piazza draw the closed outline with highway=pedestrian which would normally render as a closed loop, but if you add area=yes the whole space is rendered as a filled piazza.

I've reported such an error a while ago on WIKI: http://wiki.openstreetmap.org/wiki/Talk:Coastline_error_checker Yeah, basically, there is some rounding done to simplify the polygons so that stuff that makes no difference in rendering gets filtered away. If the island is really small the end effect is that the simplification leaves an area consisting of a single point, and so it complains. I could ofcourse stop it complaining, but the islands wont appear in the output anywhere...

Coastline traces are often inaccurate, and often displaced. The best option is to adjust them manually. At least in JOSM I can move the landsat layer. So I'll try to match the landsat layer to known features, for example roads visible on the satelitte images. Then, I'll move the coastline manually so that it matches the landsat images A bit tedious, but I'll normally always do it if I map so close to the sea that this accuracy becomes important. -- - Vegard Engen, member of the first RFC1149 implementation team. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
