Moin[1]. My name is Hauke and I'm currently doing my master's degree of computer science in Hamburg, Germany. I'm contributing to OSM since April 2019 with focus on buildings, streets/ways, hydrants, cycle infrastructure, POIs and detailed mapping of all kinds of things.

I also write software and created e.g. the Simple Task Manager and the android app GeoNotes. There are some more projects listed below.

Apart from OSM, I have a (currently inactive) blog about IT stuff and another blog about my hiking and trekking. I also contribute to Wikipedia, Wikidata and Wikimedia whenever I have something interesting to contribute. Mostly in combination with OSM data I'm mapping.


Mapping activities


I add many hydrants and try to organize by efforts.

Problem with cycleway=street Hamburg

Some user used the tag cycleway=street in Hamburg, Germany. To turn this into valid cycleway-tags there was some discussion and I created a map.


Currently only one:

  • tax_free_shopping: Some shops offer a direct tax-refund (e.g. at airports) or indirect refunds via third-party companies (e.g. "Global Blue"). The new key is duty_free=*.

HOT mapping

I'm contributing (or have been contributing) to projekts in Ghana and Malawi:

WIP: Cleanup of bollard tags

See Mechanical_Edits/hauke-stieler_bollard_cleanup_germany for further information.

Software development

Actively developed

  • SimpleTaskManager: A tasking manager (like the one from HOT or MapCraft) but simpler. (GitHub)
  • GeoNotes: An android app to create georeferences notes and photos. (F-Droids)
  • OSM Open: An web application to find open things at a specific point in time (e.g. everything that's open tomorrow at 15:30)
  • OSM OAuth 1A dummy server: FOR DEVELOPMENT USE ONLY! A server that emulates parts of the OSM API (OAuth and some user details API enpoints).

More or less abandoned projects

  • OSM changeset crawler: A quite fast analyser of changesets e.g. by keywords in comments or by missing source-tags.
  • GPX smoother: A tool to make recorded GPX tracks a bit smoother.
  • image2tiles: Cuts an image (e.g. a scan of a hiking map) into XYZ-tiles, which can e.g. used in JOSM.

Other stuff I do

This wiki

Of course I also contribute to this wiki.


I'm doing workshops on topics like "how to contribute to OSM" at the university of Hamburg, Germany. For this purpose, I created slides introducing OSM, application, the data and how to contribute.

Other wikis

I also contribute to Wikipedia, Wikimedia commons and Wikidata as well.

  1. Moin (/ˈmɔɪn/) is a short greeting from northern Germany and it just means "Hello, long time to see, how are you? What a great day, isn't it?". Saying moin moin is also common but already considered to be a whole conversation.
