Re: [OSM-fi] Fixing broken and old-style multipolygons
Hi, Right, those seem to come from the notorious Corine Landcover import that was never completed nor reversed even it does have loads of topological errors. It does bring some colour to the map in about 25% of the Finnish territory, though. You may know that we do not have very good alternative sources for land cover imports because 71,6% of the area of Finland is covered by forests. Therefore our topographic map database does not even have a class for forests - they are background, not interesting at all. I had a look at some polygons and I do not know exactly how they should be corrected. For example relation https://www.openstreetmap.org/relation/1481481#map=8/62.740/25.565 It has an inner member https://www.openstreetmap.org/way/104644001 which somehow looks the same as https://www.openstreetmap.org/way/104646035 The inner polygon, that is coniferous wood, is a simple polygon with only outer ring. So as a stand-alone it could carry its own tags. But because the ring is re-used as a hole of the bigger mixed wood polygon it should not have tags. Instead the single ring coniferous area should be changed into a multipolygon relation that has only one member, and that new relation would get the coniferous tag. Is this correct? I really much doubt that anybody is interested in correcting the Corine polygons but people has not been too eager to revert the import either. Because of the colour, you know. But let's see how other members of the Finnish community react. I fear also that OSM will never get rid of the hand-written multipolygon relation system and because the reason for the trouble will not be fixed you have been forced to start your huge effort with fixing the broken data https://wiki.openstreetmap.org/wiki/Area/The_Future_of_Areas.

Re: [OSM-talk] DB Performance (was: JOSM plugin to import GeoJSON?_
Hi, Stefan did not tell enough details for repeating the test exactly so my test set-up is probably a bit different. Program: GDAL 2.1.0dev, released 2015/99/99 on Windows, compiled with sqlite-3.10.2 and libspatialite-4.3.0a Test data: 100 points (2D) without attributes in shp format Storage: USB 2.0 drive, same disk used for both input and output Test script which is also testing a performance hint about turning synchronous write off: @echo %time% ogr2ogr -f gpkg plain_points.gpkg plain_points.shp @echo %time% ogr2ogr -f gpkg plain_points_nosync.gpkg plain_points.shp --config OGR_SQLITE_SYNCHRONOUS OFF @echo %time% ogr2ogr -f SQLite -dsco spatialite=yes plain_points.sqlite plain_points.shp @echo %time% ogr2ogr -f SQLite -dsco spatialite=yes plain_points_nosync.sqlite plain_points.shp --config OGR_SQLITE_SYNCHRONOUS OFF @echo %time% ogr2ogr -f SQLite -dsco spatialite=yes plain_points_nosync_gt.sqlite plain_points.shp --config OGR_SQLITE_SYNCHRONOUS OFF -gt 65536 @echo %time% Timings from the 5 runs: 1: 38 seconds 2: 38 seconds 3: 41 seconds 4: 37 seconds 5: 39 seconds Conclusions: 1) In my tests with my data, software, and hardware, there were no meaningful differences in the conversion speeds. Test data of one million points may be too small or then the conversion needs so little computing that I was actually measuring the I/O speed of the USB drive. 2) Stefan measured a creation time of 1 min 51 sec for the Spatialite. There must be something in that. Fresh GDAL uses a default value of 2 for -gt (not corrected into all GDAL documents) and using -gt 65536 did not make any difference with GDAL 2.1-dev. However, with explicit -gt 200 the timing was 93 second so it may explain most part of the slow result. 200 is what old GDAL versions use as a default value for -gt which makes 5000 transactions for one million points. Stefan, which GDAL version did you use? Could you make a new test with bigger -gt value and if needed, re-consider your conclusion "Spatialite is several times slower for creation time". Could it rather be "Transactions are expensive with SQLite, try to avoid making too many"? File sizes of my test data which had million points without attributes: shp: 35 MB gpkg: 92 GB splite: 130 GB I took also a sample of one million points from a real world dataset with attributes: three doubles, two dates, and two strings and that changed the numbers quite a lot: shp: 170 MB gpkg: 153 GB splite: 185 GB No huge differences is file sizes when data have attributes. -Jukka Rahkonen- Mike Thompson wrote 2016-03-23 03:26: This from the ogr2ogr documentation[1] may be relevant: "When writing into transactional DBMS (SQLite/PostgreSQL,MySQL, etc...), it might be beneficial to increase the number of INSERT statements executed between BEGIN TRANSACTION and COMMIT TRANSACTION statements.

Creation time of GeoPackage was 18 sec., Shapefile 21 sec. and Spatialite 1 min 51 sec. So, GeoPackage is a bit faster than Shapefiles and significantly (about 37%) smaller in size. Spatialite in fact consumes much more disk space than Shapefile and GeoPackage, and Spatialite is several times slower for creation time.

Hi Frederic, I would like to receive some sample data, exact way to reproduce some of your ventures and cold numbers about the speed you have experienced. Spatialite does have it's limits but for plain selects with spatial and attribute filters it can well outperform both shapefiles and PostGIS. I keep most vector data for WMS services in Spatialite or GeoPackage due to the already mentioned and some other reasons: - supports long attribute names - supports strings longer than 255 characters - supports SQL - supports attribute indexes - much less encoding problems due to UTF-8 - one single file vs. a bunch of files in shapefile, perhaps even split to separate bunches for points, lines and polygons. For me SpatiaLite is a little bit slower than shapefiles if only spatial filter (BBOX) is used but usually faster if also attribute filters are involved, especially if more than one field is needed in filters (Shapefiles can be sorted by one attribute only). Of course spatialite must have indexes which suit the queries and when it comes to spatial index, the client must know how to utilize the table based R-Tree index. I also recommend to VACUUM once the database is ready to use. Many spatial operations are relatively slow in Spatialite and I don't usually utilize them on-the-fly with WMS server. Instead, I run the algorithm once and store the result into a new table because a few mega/gigabytes of additional disk space is not crucial on the server. However, such operations tend to be slow also if shapefiles are used as source data. Write performance especially with concurrent writes is another story. I am talking about read-only operations. I know that I am writing empty words as far as I do not include reproducible facts but I am willing to join to a controlled test if someone is organizing such. -Jukka Rahkonen- ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk

It's frankly the easier route but it would be a real shame if OSM isn't the venue to make it happen. I have been thinking that perhaps that would be the best route anyway even if Mr. Coast gets elected to the board. By my own experience about the addresses in OSM they feel fuzzy and somewhat difficult to utilize outside OSM. Addresses given to building polygons are quite simple to move to centroids of the polygons for making a point layer of all the addresses but for example finding the municipality or city for the address points is tedious because administrative units are defined as relations which are also somewhat fuzzy and all too often broken. With a dedicated database and tools for addresses the route could really be easier and faster and I would not feel ashamed at all while importing addresses from this master address database into OSM later. -Jukka Rahkonen- ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk

Hi Simon, We have considered that we cannot use OpenStreetMap as a background map in any of the applications where users are sending location aware information back to administration. For showing existing data it would be OK but not for gathering data from users because user could locate a place corner of Annankatu and Merimiehenkatu http://osm.org/go/0xPLoLTa0?m= by looking at the OSM map. The interpretation of ODbL is that this location is derived from OSM data and thus the database of the administration would become ODbL. It could be OK in some use cases but some data are confidential and ODbL is not an option. Therefore we do not use OSM at all. We use our own services and Google Maps. This is a concrete example. However, changing the interpretation of ODbL into georeferencing locations by looking at OSM map does not yield a derivative database would not necessarily change the situation in Finland any more because since 2012 most raster and vector data from the National Land Survey of Finland have been open data under attribution-only license. Because of this using the data is simple. This has also helped OSM because raster maps and aerial images can be utilized for digitizing and vector data imports have started this year.

[OSM-talk] Geospatial PDF maps from OSM data
Hi, I wrote a tutorial about using some new features of the next GDAL version 1.10. It is a GDAL tutorial but the examples are using just OSM raster and vector data so they may interest also this audience. PDF is not anything special and we do already have PDF export option in the OSM main map but these recipes bring also coordinates and OSM tags into the PDF map and users can themself decide what OSM features to add on top of the base map.

Thank you to each of you for all the work you do! Hi, Sorry for a bit delayed answer but GDAL/OGR OSM driver developer had to do a couple of fixes for making this task to perform well. So you can do all that with GDAL OSM driver and SQL query language. Output can be despite CSV any other format that is supported by GDAL/OGR for writing. http://www.gdal.org/ogr/drv_osm.html http://www.gdal.org/ogr/ogr_formats.html Install a very fresh GDAL development version, about rev. 24970 or higher. For Windows you can get it from gisinternals http://www.gisinternals.com/sdk/ You want to query streetname from osm lines and name and probably some other attributes from osm points and from a limited area. It is possible but quite slow to create such CSV file directly from OSM data file that can be in osm-xml or pbf format with following command ogr2ogr -f CSV streets.csv finland.osm.pbf -sql select distinct name from lines where highway is not null order by name -spat 24.821 60.123 25.259 60.317 However, it is faster, especially if you want to do more queries, to convert OSM data first into Spatialite database. Here is a quite optimised command to use as a template ogr2ogr -f SQLite -dsco spatialite=yes finland.sqlite finland.osm.pbf --config SQLITE_SYNCHRONOUS OFF --config OSM_COMPRESS_NODES YES -progress This conversion takes a few minutes with 130 MB finland.osm.pbf file. Then you can repeat the first streetname search and it will be pretty fast ogr2ogr -f CSV streets.csv finland.sqlite -sql select distinct name from lines where highway is not null order by name -spat 24.821 60.123 25.259 60.317 The poi file can be created in a similar way.

Read the OSM driver manual page. The second command does not work before editing the defauld osmconf.ini file so that amenity is included in the points layer attributes. Note 2. There is a little bug in ogr2ogr CSV driver that may prevent creating a new csv file if there is already another CSV file with an uncommon structure in the same directory. The one-column CSV file that was created in the first example has such a structure. Delete the file or rename it with another extension before running the second example.

The main message was that perhaps there is a need to do some tests before saying if hstore or joined tables are faster. Here is a Spatialite database for testing http://latuviitta.org/documents/relation_test.zip First trials suggest that joined tables with proper indexes are not at all slow and compared with the standard tables created by osm2pgsql the query times can be several times faster. This is not a fair comparison because osm2pgsql tables are missing the attribute indexes but so they normally do in the Mapnik chain. Query times vary, so try yourself. Data is osm_lines from Berlin from some months ago. By the way, recent development around GDAL suggests that Spatialite may be faster with spatial and attribute queries than PostGIS. Improvements in GDAL Spatialite driver made Mapserver about 20 times faster than it used to be and now Spatialite is faster that PostGIS and even shapefiles. query from osm_line from osm2pgsql === select geometry, highway from osm_line where highway='primary' 0.531 seconds query from joined tables === select * from line_geometry, tags where tags.tag='highway' and tags.value='primary' and tags.join_id=line_geometry.osm_id 0.059 seconds -Jukka Rahkonen- ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

I never ran one with hstore when I think of what this must mean for the database engine, and storage space, then I shudder and would not be surprised by the factor 5 you mentioned. How about doing it with relations? Let the importer program create four tables osm_point osm_line osm_polygon osm_relation These tables would each have two attributes: Geometry and osm_is. Geometries in the osm_relation would be of type geometry collection, that is, a collection of whatever, and it could hold for example the tranport route relation with the route and bus stops and everything in one PostGIS geometry object. Then there should be one or four tables for tags (everything in one table or split to suit the geometry tables). The three attributes would be osm_id, key, and value. Osm_id would be used as a foreing key for joining geometries and attributes. If osm_id can not be guaranteed to be unique then there should be point_id, line_id, polygon_id and relation_id added to suitable places. Every attribute would be indexed. For Mapnik use where all that is needed is to do simple SQL selects. I guess that this database would be faster to query than hstore even it also contains all the tags. It might be faster for Mapnik than the current tables with extra wide attribute schema because now attributes are not indexed at all (or are they?). SQL queries according to tags and values or even with a part of the tag and value strings would be easier to do than from hstore. People could enhance attributes for some special uses by converting max_speeds and other values which are actually measures from strings to integers or doubles etc. This option is so obvious that I believe that someone must have tried it already.

[OSM-legal-talk] Copyright and License in WFS service
Could you tell what is the proper way to credit OpenStreetMap in a WFS service? I am planning to start keeping my WFS server solidly up and I would like to have a few OSM datasets in the service. In the beginning they would be the osm_point, osm_line and osm_polygon layers which are the standard PostGIS layers created by osm2pgsql with the hstore option for keeping all the tags. In addition the service would contain some data from the National Land Survey of Finland (NLS). The NLS datasets have a more permissive license than OSM data, NLS open data license which is attrirution only and pretty close to CC-BY. WFS standard defines the AccessConstraints element in the service metadata and I have sketched to have there a text like + Access Constraints == Contains Map data from OpenStreetMap contributors http://www.openstreetmap.org/ licensed under the Creative Commons Attribution-ShareAlike 2.0 licence (CC-BY-SA) http://creativecommons.org/licenses/by-sa/2.0/ Check also additional OpenStreetMap constraints http://www.openstreetmap.org/copyright? Contains map data from from the National Land Survey of Finland licensed under the NLS open license http://www.maanmittauslaitos.fi/ilmaisetaineistot + Would this be enought? WFS service metadata can be obtained by doing a GetCapabilities request http://188.64.1.61/cgi-bin/tinyows?service=wfsversion=1.1.0request=getcapabilities However, it is possible to download data from the service without ever doing the GetCapabilities request by sending http://188.64.1.61/cgi-bin/tinyows?SERVICE=WFSVERSION=1.1.0REQUEST=GetFeatureTypeName=osm_pointmaxfeatures=20 In this case the OSM data have been imported with osm2pgsql and after that there are not much left in the data to tell that they come originally from OSM.

[OSM-talk] PD aspiration statistics
Hi, The licensing working group has been discussing about a thing called PD aspirations https://docs.google.com/View?id=dd9g3qjp_113gtw62wdf Excerpt from the minutes 5. OpenStreetMap PD-Contributor Terms Freimut Kahrs wrote to us concerning an issue that has recently emerged on German and international blogs and mailing lists, suggesting that mappers should be able to choose between two different Contributor Terms offered by OSMF: 1. CT-ODbL (the current 1.2.4 Contributor Terms) 2. CT-PD , which releases personal contributions into public domain and allows direct use as such by end users of the OSM geodata set. A discussion concluded that there are disadvantages. It was also felt that, while attractive to a segment of the community, it goes against the 2007 consensus of choosing the latter of going PD or go something like CC-BY-SA but written for data. We noted that we are already giving an opportunity to folks to indicate their PD aspirations. It would need work on whether it is legally feasible and would also require changes to OSM's end user licensing, i.e. not just ODbL. Are there plans to publish some day the statistics about how many users have been willing to indicate their PD aspirations and how wide a segment we are talking about? Without statistics the bare opportunity to indicate PD aspirations is not very much to be happy about. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Re: [OSM-talk] Mapping huge lakes as coastline
Teemu Koskinen teemu.koskinen at mbnet.fi writes: I converted a few of the biggest lakes in Finland a few years ago to coastlines, and they worked fine, until last year some other user converted them to multipolygons with natural=water -tags. He also splitted the biggest lake (Päijänne) in pieces, which created arbitrary lines across the lakes at random where the lake was divided to different polygons. The biggest lakes in Finland have tens of thousands (or even hundreds of thousands) nodes and a LOT of islands, so it's not practical to represent them as (multi)polygons IMO. It is not practical, either, to represent them as coastlines. For example osm2pgsql is not importing coastlines into PostGIS at all but users must use the processed land polygons as shapefiles for rendering these coastline lakes. One may say it works fine with Mapnik rendering because of this shapefile workaround. Some could call it as a dirty hack. For example, it gets complicated when somebody wants to add tags for the lakes and islands. By the way, i checked that the biggest lake polygon in the data of the National land survey of Finland is the lake Saimaa, and it has exactly 287273 vertices and more than 5000 islands. It is a bit heavy to handle in PostGIS and Oracle Spatial and with GIS programs but not at all impossible. There is a wiki page about the future of areas in OSM.

Basically I do not care about rendering but I have an interest in plain data. I am after interoperability without a need to import everything into OSM first. I would like to do spatial queries from the database and through web services and see what features and what tags OSM users have recorded around a given place and do comparisons with data from other data sources.

The question by Richard Fairhurst (2008 October 9) Interesting (I know, I know, I should get a life). But if the nice chaps at Richmond tell you there’s a recycling box at the corner of Park Lane and Park Road, and you use Google (map or satellite) to determine that said corner is at 51.425297,-0.334935, isn’t that a derivation? Because it would be really, really cool if it wasn’t. The answer by Ed Parsons (2008 October 9) @ Richard, OK so this is really cool then, as I can use Google maps to determine the actual location, as it both does not occur on the original map or at Richmond’s website. It is the product of my interpretation in this case based on local knowledge and the imagery therefore it is not derived ! Niklas is having very analogous use case. He took a photo and he knows he was standing at the corner of Park Lane and Park Road. If he then looks at Google maps and takes the coordinates for geotagging his photo, Ed Parsons seems to think that the geolocation of the photo is not derived. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

I remember that Frederik has used a word interoperability in some of his mails. Most OSM folks seem to think that interoperability means either a) transparent tiles and OpenLayers or b) vacuuming all the geodata with somehow suitable license into OSM. I believe there could be also other ways. It is understandable that road data are imported into the main OSM database because we have lots of our own highway data with better and more up-to-date knowlegde about road attributes. Road data must also be noded for making it suitable for navigation and OSM data model with the spaghetti topology and all the data on a one single layer suits this use. However, some of the data which have been imported could as well be used from somewhere else, like from a separate OSM-Import database or from an external service. Use of SRTM countour lines in OpenCyclemap, Openmtbmap and in some other places is one (only?) good example about using non-OSM data together with OSM data without imports. It is not really a pleasure to try to follow the rules given in documents like http://inspire.jrc.ec.europa.eu/documents/Network_Services/INSPIRE%20Draft%20Technical%20Guidance%20Download%20%28Version%202.0%29.pdf Still I think that it is better this way than by having a huge Central Spatial Data Infrastructure database in Brussels.

A telephone number is a fact in the sense that it is it's own identity. A copy will be identical. And this seems to be the basis of much US case law in this area.

[OSM-talk] OpenJUMP supports live GPS with OSM data now

I did some testing with the rc4 version and wrote some lines with screen captures into https://sourceforge.net/apps/mediawiki/jump-pilot/index.php?title=GPS_plugin Some features: - Unlike GPSD based solutions like JOSM livegps plugin, OpenJUMP GPS extension works with Windows - Nothing OpenStreetMap specific included. OpenJUMP can open shapefiles and read data from PostGIS database. OSM shapefiles from Geofabrik or Cloudmade can be used as such, as well as OSM data imported into PostGIS database with osm2pgsql. Also the new 'tags' column of hstore datatype is supported and therefore all the OSM tags can be accessed by OpenJUMP if the PostGIS import has been done by using the -k option - OSM can combine OSM data with anything else that can be converted into shapefiles or PostGIS, including data from all the various OSM forks we may have :) - Georeferenced images and WMS services can be used together with vector data. - Not suitable for OSM editing. Edits can be saved into shapefiles and with some struggle converted into osm format with tools like ogr2osm.py for further processing with JOSM but it's tricky. So no, OpenJUMP is not an OSM editor. - No routing. Osm2pgsql brakes the topology and even there has been some pgrouting plugin for OpenJUMP I would believe it won't work well with OSM data. Some kind of a workaround is to download route from Cloudmade in gpx format, convert it to shapefile and add then as a new layer into OpenJUMP map. -Jukka Rahkonen- ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Sooner or later the streets and buildings will disappear from the OSM-ODbL but what will happen to the POIs? I suppose there are folks who say that also these POIs should be deleted from (or not transferred to) the OSM-ODbL database because they are derived from the CC-BY-SA only data.
