I installed a new, very professional firewall with spam protection – its not free, but there’s no alternative.

A nice bonus is that the system is also GDPR-compliant – whatever you may think of that.


I hope that

a.) Life will become easier for us admins
and above all it
b.) there are no more annoying blockades of legitimate users, a situation that is/was very unpleasant for everyone.

The update plan for the maps this summer will be published separately.

So long,
Your OpenAndroMaps team

Translated with DeepL.com (free version)

All maps are now re-rendered and available for download.

The Taiwan map has now also been updated, the programmer of the Mapsforge library was so kind to adapt the map writer to the enormous density of data there.


The next update will be available at the beginning of September.


For us the development of OpenAndroMaps is going on, there are plenty of things to think about.


We wish you a nice summer and pleasant trips with the OpenAndroMaps.

Greetings, Tobias, Michael, Christian

And there we go,


As all those who have ever met me probably guessed, my sense of order is stronger than my frustration and I have written a script for the resolution of the screwed-up super routes and integrated it into the process.


And because I enjoyed that typing so much, I changed the generation of the REFs (= short names of the routes).
Until now, the REF – if there were capital letters in the NAME and no REF-Value – was formed from these.
So e.g. “West Coast Trail” = WCT
Unfortunately, there are also relations which, especially in Scandinavia, had the path name_+vegur +vegen etc. in the NAME. This ended up in a REF that only consisted of the first capital letter.

From now on, the capital letters only become effective when at least TWO of them are recognised.
If there is only one capital letter, the first 5 letters of the NAME are used to form the REF.
So “Fjärilsleden” was REF=”F” until now, from now on REF=”Fjäri” – looks much, much better.


I did allow myself a new POI, namely the “E” charging stations relevant for EBikes without the obligation to consume (Pub,Restaurant…).
These can be found in the POIs under hike/bike, I think this is also of interest to one or two of you.
Here is the exact implementation: https://www.openandromaps.org/oam-forums/topic/ebike_charging_public-2


Perspective: In the course of the discussion about the ICN/IWN + super routes, it came up again that the “big” routes cover the small, local cycling/walking routes too often – we are currently discussing possibilities to switch off the international routes, but this is an essential intervention in the structure of the maps and must be considered = this will take a little time.


So, I wish you a pleasant Summer

Best regards,

Dear OAM community,


I am forced to suspend further updates of the maps = there will be no more updates for the time being.

Reason: A mapper has begun to “normalise” hierarchies of wheel relations that have been carefully maintained over the years.
This means that the previously common consensus – that the individual cycle relations, such as the Eurovelo routes, consisted of a hierarchy of main (super) relations with individual sub-relations (the countries), each containing all the necessary information – has been destroyed.

Now there are super-relations that are based on other super-relations, relations that cross-reference other relations, etc….
Unfortunately, this cannot be resolved with the hand-programmed tools of the OAM for the time being, as there is no way to resolve the possible cross-nesting of the super/relations 100% conclusively.

For the time being, the Scandinavian maps are affected – but it is foreseeable that this cancer will spread further.

Up to now, I have been able to iron out such improvements to the OSM database relatively quickly and without any major complaints, but now it’s time to take a break.


I am real terrible sorry for the community, my comrades-in-arms @Tobias and @Michael and all those who have contributed to this project in any other way, but at the moment I have reached the point where I simply don’t want to chase after every nonsense like Don Quixote against windmills.

Should something similar to quality control be introduced to OpenStreetMap at some point, I would be happy to become active again.


Have a nice summer
Your Christian

PS: Of course I will remove the donate buttons.

The download.openandromaps.org has been disabled and should not be necessary anymore since all links lead directly to the actual download server

This subdomain was a relic from the early days of OpenAndroMaps before the University in Göttingen took over the hosting of the maps. In those days the download sources changed regularly (Megaupload, GDrive, etc..) and to provide a constant URL the downloads.openandromaps.org was set up – which itself never hosted any files but only forwarded to the actual hosters.
With GWDG as our longtime, free!!! map hoster, the subdomain has not been needed for quite some time.
If GWDG should ever withdraw their support for the OSM project, there is no alternative anyway, since the monthly traffic volume for OAM alone is in the terrabyte range.

So, no more downloads.openandromaps.org.

Please just use the links from the website and update your bookmarks

If any links on the OAM website are dangling in the air and still point to downloads.openandromaps.org – please post a message.


LG, Christian


Unfortunately, the loading times for the non-cached part of the OAM website have been indisputably slow for about a week.
This is partly due to a much higher number of hack attempts (greetings to St. Petersburg – I hope the weather is pleasant).

I am currently working with the hoster on a solution that will be fast AND easy to administer again.

Until then, please bear with me…..

The already announced new map generation is now ready to be released for download.
With this new generation, fundamental design weaknesses such as common hike/cycle route names or fragmentation of MTB routes in some cases have been resolved.

The new features meant a deep impact on the production structure of the maps.
New hardware on which the new V5 Mapsforge Writer from EMUX runs smoothly and a complete rewrite of most software was necessary.

Here are the new features in a nutshell:

  • The MTB routes are now rendered independently and according to categories (like the cycle routes) – this means that interregional MTB routes such as in the UK or the Granittrail in the Waldviertel are prominently highlighted.
  • Overlaps between bike and MTB routes are now neatly resolved.
  • Short names of MTB/bike/hike routes are now separated
  • The links between route nodes (NL) are now rendered later on
  • Dozens of OSMC hiking symbols are added….

What needs to be done on your side: An update to the render theme – when installed directly on Android in Locus, the theme is installed/updated automatically.

Thank you for your feedback during the beta test, where a profound bug was discovered and fixed.


Have a peaceful Christmas,
We wish you good health and beautiful walks in the winter-snow

Unfortunately, the cloud server has completely crashed, and restoring the existing backups did not help either.

I have now moved the website to a normal web space and will try to get the whole thing up and running again tomorrow.

At the moment, there will probably be problems with the redirects – this mainly concerns the direct install on Android.
This will also be taken care of tomorrow in the course of the day.

Sorry for the trouble.

PS: The registrations and forum posts of the last 24h are unfortunately also lost, sorry.

Many people might ask themselves: “Why Excel for an OSM map project?
Well, with OAM there is a stock of around 270 maps to manage with the most diverse settings.

For example, map symbols for petrol stations and drinking water sources in urban areas appear only at much higher zoom levels than in Scandinavia – for this, there is also the ELEMENTS theme by Tobias, which takes this into account. This means that different tag mappings have to be created and assigned to individual maps.
But also such trivial things as map centres, languages, fineness of elevation data, allocation to render queues (load balancing) have to be managed. Corresponding start-up programmes for each individual production step such as conversion of file formats, creation of boundary polys, elevation data, sea areas, inheritance of bike/MTB/hike routes etc,etc. – belong to !automated! production.

Last but not least, the web pages must be regenerated after each update.

This is impossible to do manually, so far Excel-VBA programmes in combination with PERL scripts have done most of the hard work.


For about 10 days now, I have been sitting in front of the computer every free minute and porting VBA to Starbasic. Porting means cleaning up 9 years of organically grown programmes and simply rewriting them, leaving out my beloved PERL for pure administration jobs.
In addition, a flexible folder structure was implemented to allow porting to other machines and effective load balancing/caching.


With the switch to a free office package and the cleaning up of the programmes, it is now much easier for my co-authors to familiarise themselves with map production in OpenAndroMaps. 


The first maps rolled out today from the LibreCalc generated start scripts, the automated creation of the download pages will be addressed next week.


New rendering machine: Thank you very much for your donations – most of the parts for the PC have arrived and are awaiting assembly, which will be started after the next map update if there are no unexpected problems with the software port.
For me this is a great reassurance as it means that the test computer will go to @Michael and thus 10 years of accumulated knowledge about vector maps will be preserved.


There will be more detailed information about the new render machine.
Here in a nutshell: AMD Ryzen 5600G, 128GB RAM, ASUS MB, 2TB 970evo Plus as standard drive, 1TB Toshiba SSD for the planet extracts and height data, NOCTUA fans, new semi-passive power supply, as well as various used parts from the spare and new fans for the old case.
Should my time run out, this computer will also go to @Michael.

best wishes and stay healthy


Dear OAM community,

In a nutshell:
I had been struggling with health problems for quite a while this year. I would like to say  THANK’s to my comrades-in-arms Tobias and Michael who have kept up the support here.

I am now looking forward to a long overdue holiday trip which I will start next week and which will – hopefully – take me to the far north.

Which means that the next map update, any bug fixes and improvements will continue in August (at the moment the computer is runnig full speed and every map rendered until Friday will be uploaded). I hope for your understanding.

Looking back on the first half of the year, a lot of improvements have been made to the maps – and Sonny has been busy adding the LIDAR elevation contours.
The Scandinavia_North map will be replaced by a Scandinavia_NorthEast map. From now on the maps Scandinavia_SouthWest + Scandinavia_NorthEast cover Scandinavia completely.

Until autumn, stay healthy and
(again) nice tours with the OAM
