<div>Can you link affected data in Poland? <br></div><div><br></div><div>In Poland you actually can reliably estimate real tracktype based solely<br></div><div>on high quality aerial images (not satellite imagery that is unlikely to be <br></div><div>sufficient), typically Geoportal 2 aerial and LIDAR data available in ISOK Cień dataset.<br></div><div><br></div><div>Note that your planned automatic revert likely counts as automatic <br></div><div>edits and needs to fullfill<br></div><div><a href="https://wiki.openstreetmap.org/wiki/Automated_Edits_code_of_conduct">https://wiki.openstreetmap.org/wiki/Automated_Edits_code_of_conduct</a><br></div><div>requirements, including support from other editors.<br></div><div><br></div><div>Jul 18, 2020, 12:53 by osm-ml@michreichert.de:<br></div><blockquote class="tutanota_quote" style="border-left: 1px solid #93A3B8; padding-left: 10px; margin-left: 5px;"><div>Hi,<br></div><div><br></div><div>while reviewing changes in my local area, I discovered that user Modest7<br></div><div>has been adding tracktype=* tags to lots of highway=track at various<br></div><div>locations. I asked him what sources he used apart from the satellite<br></div><div>imagery mentioned in the imagery_used=* tag of his changesets. See<br></div><div>https://www.openstreetmap.org/changeset/87236896 for a discussion with him.<br></div><div><br></div><div>I do not believe that one can add reliable tracktype=* information from<br></div><div>satellite imagery without having some ground truth knowledge in order to<br></div><div>know how to interpret the imagery in that region. Adding estimated<br></div><div>tracktype=* does not help OSM on the long term. People how rely on the<br></div><div>information (e.g. some wanting to drive or cycle on that track) are<br></div><div>disappointed about this low-quality OSM data. Mappers who decide where<br></div><div>to map assume these roads to be mapped properly. IMHO, adding<br></div><div>fixme=resurvey tracktype will not improve it. Data consumers usually do<br></div><div>not use tags like fixme=* In the case of imports (another type of mass<br></div><div>editing), we say that an import must not add fixme=* to cover<br></div><div>shortcomings of the data to be imported because they usually do not get<br></div><div>fixed in a reasonable time. Therefore, I plan to revert these changes.<br></div><div><br></div><div>Modest7 does not seem to realise that estimating tracktype from<br></div><div>satellite imagery is not doing a service to OSM. I am currently<br></div><div>preparing a revert of all additions of surface=* and tracktype=* by him<br></div><div>he uploaded since 1 January 2020 [1]. The revert will only edit tags,<br></div><div>geometry will stay unchanged. I revert changes on surface as well<br></div><div>because that's not very different to tracktype except that it applies to<br></div><div>other types of roads as well.<br></div><div><br></div><div>The countries which will be affected are:<br></div><div>Germany<br></div><div>Denmark<br></div><div>Turkey<br></div><div>United States<br></div><div>Poland<br></div><div>Ukraine<br></div><div>Morocco<br></div><div>Czech Republic<br></div><div>Lithuania<br></div><div>Sweden<br></div><div>Norway<br></div><div>eSwatini<br></div><div><br></div><div>A changeset discussion with him can be found at<br></div><div>https://www.openstreetmap.org/changeset/87236896<br></div><div><br></div><div>Best regards<br></div><div><br></div><div>Michael<br></div><div><br></div><div><br></div><div>[1] This date is not fixed yet.<br></div></blockquote><div><br></div> </body>
