First off: I really want to express my thankfulness on Histor’s work on it’s own Histor style map. But that being said, I also want to open a debate on the style itself and which direction it could go, which might be controversial: what about a complete overhaul of the Histor style based on the current standard mapnik style? Back in the days, I assume Histor style used to be a derivative of the then standard mapnik style, but with extra features such as ports, railroad differentiation, i.e. all things the standard map style lacks. But then the standard style had a complete redesign, and the Histor style didn’t follow and kept the old style. And now, Histor is editing the style to fix the problems the old style had, and which is exactly the reason why mapnik itself changed to its new style too. But the problem with that is, with all respect, the current Histor style seems a bit… amateurish. And that’s normal, because the new standard mapnik style probably took a ton of work by a lot of different people to get at the point it is now.

I’m quite new to the OGF community, but I have much longer experience on OSM. On OSM I got quite used to extracting data through Overpass and then editing the desired dataset in JOSM. Since the time I’ve been here on OGF, I’ve tried and constantly failed at doing the same with the dedicated OGF Overpass, only to find out it’s simply impossible. This is because the Overpass server stores no metadata anymore since the GDPR law went into effect, and that metadata is required to edit the dataset in JOSM. But… I found a workaround! I wrote a one click script to extract all IDs from a .osm Overpass dataset into a single list, so you can easily paste this into the ‘Download objects’ dialog in JOSM. JOSM will then download exactly what you previously got as output from Overpass Turbo, and you’re ready to edit right away!

So how do you get this to work? First you have to download your data from Overpass Turbo as you would normally do (‘out meta’ isn’t necessary, ‘out skel’, ‘out geom’, ‘out’, or even ‘out ids’ will all do the job). Then click ‘export’ > ‘raw data’, this will download a file called ‘export.osm’. Next you run the script you can download here by simply double clicking the batch script which will run the other script (which is a PowerShell script). Make sure the export.osm file is in the same folder as the script. The script will run and in a matter of seconds you will have a new file called ‘List.txt’ which contains a list of all IDs, and they’re automatically copied to your clipboard too. In JOSM, paste this list into the ‘Download objects’ dialog. Make sure object type is set to ‘mixed’, and in your JOSM preferences the checkbox ‘Use Overpass server to download objects’ is disabled in the connection settings. Then you just have to click ‘download’ and voila, your data is loaded into JOSM.
