Open Street Map


Open Street Map

It is probably well-known that I like open source. Since some months I spend a lot of my free time by editing the Open Street Map (OSM). I would like to introduce you to this project, which will come across everybody’s future as Wikipedia did.

OSM is an open source project which’s goal is to provide a map of the whole globe and as Wikipedia does, it invites everybody to contribute new data under a creative commons license. Analog to the Wikipedia you can create a profile, edit the map, observe map sections, read the history, write blog posts and some stuff more. Things which are necessary for every open source project.

The power of the map is not that obvious. Maybe the map looks nice or maybe not that nice as Google’s map looks like. Just imagine that everybody is allowed to create his custom map: An historical map of the town you are currently visiting or a map where you can find every important information just. Of course there are already maps at the website of OSM. For example the cycle or traffic maps. But there are also smartphone apps as OsmAnd (which is open source, too) which enables you to check for the next café, ATM or just a toilet.

But there are also some amazing projects like the Isometric 3D maps project or the OSM tool Nominatim. Or the routing service “Open Route Service” of the University of Heidelberg.

You will find much more interesting applications of the Data just by searching the internet. Just put “osm” into your request.

And to finish this blogging day I send some sweet regards to…





Seeding radish


It is spring, so the seeding time is starting and the dreams of seeding stuff in my room are blooming. Because my ex-mate and biology student had to receive a birthday present we had to arrange something. Those girls are always happy with some seeds and potting soil. Or just seeds. Because no one of […]

Tatort is a famous German crime scene which is running since 1970 and playing in Swiss, Austria and Germany. I did not find any subtitles for the newer series until now. (Since you know about subtitles (in English, German or French) I would appreciate some response though.) I am describing here how to download the […]

A new great opportunity to see auroras: I just read that a sunstorm, which was errupted last week, will hit us on Tuesday. They say that it is the strongest geomagnetical storm since the last six years. (Here is the German source) Here is some stuff related to this event: Pictures from the NASA about […]

I am still preparing for my Swedish exam and am watching Swedish videos. There are probably also some others who had problems with spots (not just me), as I just found out. Spots of juice. So here is the solution presented in a perfectly made Swedish child documentary spot with subtitles: Update: There are also […]

There are some tips I would like to suggest you. If you have a mobile PC (notebook or netbook) you can do some stuff to make it hard to take it over. This will take you (depending on how fast you will find the right options) quarter an hour. Remark: I cannot assume responsibility for […]



You may have heard about the Open Street Map Project. To view those open maps you can also use Marble. What I really like about this software is that you can download several maps and view them on a virtual ball or even on a plane map. It is not just possible to view maps […]

Why encrypting communitcation? Before I give some reasons why your communication should be encrypted, I should describe how the reality in the web looks like and compare it to the “analog” communication. The “analog” mail is written by hand or printed out and signed and in the end, if the mail is not a postcard, […]

In these days I am very busy with my acceptance of the bible. Today I decided for myself to resign from the church. The only problem is that I have to do this at Bremen. I have the best reasons for that. At least I am pretty sure that non-private religions and democracies are incompatible […]
