First of all, it is ok that an import takes a few years and therefore creates ugly green rectancles on the map. If an import is "unavoidable" :-), a manual import is the best thing that can be happen. But if someone uploads a changeset without a manual review beforehand, he counteracts the aim of a manual import: addind good data to OpenStreetMap. That's what I am mainly fighting against. If a users uploads much more than 100 objects per minute [1], you can be sure that he has not done any manual review. A manual review by myself confirmed this these. I am fighting against such changesets/users. A good imports must be reviewed *before* it is being uploaded. The review contains: - - Run JOSM validator, fix all warnings and errors. This includes all warnings regarding validity of areas. (you can argue if all warnings about "deprecated" tagging have to be fixed) - - Compare the data with available imagery. Is the forest really a forest or is another tag more appropiate? Right-click on a Bing tile at JOSM and have a look how old/recent the imagery is. - - Check if CanVec data fits to itself. http://worstofosm.tumblr.com/post/22180046353/dear-openstreetmap-isnt- it-strange-how-the - - Check if there has been any other data before. If yes, adapt the either the CanVec data or the old data. https://wiki.openstreetmap.org/wiki/File:Import-Fails-Powerlines-Not-Ins ide-Cutting.png https://www.openstreetmap.org/way/439631732 - - Ways should not overlap with other ways if it is not necessary. The outer ring of a lake should also be inner member of the forest multipolygon. Maybe the program which created the OSM files should be imprved? - - Keep the history. https://wiki.openstreetmap.org/wiki/Good_practice#Keep_the_history If a tile has been imported without being checked manually and no post-upload fixes have been done (i.e. upload without any checks), I will not shrink from reverting it. If a tile has been uploaded to OSM without a review and if it has not been fixed within a month, it is worthless and can easily be reimported at a later time if someone has the time to check and fix it. For the future, I will abstain from reverting changesets which have been imported before September 1, 2016 and whose users are currently doing the fixes that should already have been done. But if I come across an imported tile of low quality which has not been touched for a few weeks and is full of errors, it is just a question of time until it is reverte d. Best regards Michael [1] I had a look on a few of my changesets which added a large number of buildings to OSM. The fastest changeset contained about 60 objects per minute and was full of missing buildings as I later detected while collecting the housenumbers and usage of the buildings. - -- Per E-Mail kommuniziere ich bevorzugt GPG-verschlüsselt.
