Hi Vidar,

I just uploaded a new build that gives you the possibility to extend the OSM services with local map sources.

- open the application package and copy the MapServices.plist file into your application support/TrailRunner folder
- TrailRunner will then load this local file with a higher priority, so you can edit it.
- the OSM layer can now contain more than one source. I already added the TopoOSM source for the area around Massachusetts.
- To extend the sources, you can copy and paste the MA area and modify it for a different source and region.
- Please note that the ZoomLevelRange is reverse, meaning 0 in TrailRunner is the highest resolution.
- TrailRunner will check if a better source (QualityLayer) lies within the defined area (GeoCoverage).
- To create a new GeoCoverage region you can type command-d once in TrailRunner, this will display a debug red region. 
>> (more command-d's will show other regions I sometimes use, but the first is for the map source located at the last click point)
- When you click somewhere in the map and press command-c, you'll get a coordinate string you can paste.
- When you press command-alt-shift-r, TrailRunner will reload all visible map tiles and will also reload your MapServices.plist file

I write you this in the hope that you might extend the MapServices.plist with good local map sources I could then provide to everybody.
Please note that there is still one drawback:
- My engine does not (yet) support layering of OSM tiles. So the Colorado maps do not yet work as only one such source is being displayed and they are made of three layers.

Please let me know if you still have questions about all this.

cheers and thanks for your help
- berbie.
