The OpenStreetMap based maps named "OpenStreetMap - Mapnik" and "OpenStreetMap - Big" are rendered on servers that I maintain myself. myTracks does not use the official servers of OpenStreetMap.org because myTracks would generate too much traffic. However my servers do not use the latest map data of OpenStreetMap. If you want to use the servers of OpenStreetMap.org you can do so by using the file 15_OpenStreetMap_org.maplayer. Please download the file and drag & drop the file onto myTracks dock icon. After restarting myTracks you will find a new map type called OpenStreetMap.org. This map type uses the official OpenStreetMap.org servers. However, this map type doesn't support Retina displays.
myTracks caches the map data on your local hard drive. In case of the OpenStreetMap.org map type the cache is located here:
If you want to clean the cache you simply have to delete this folder.
You can also install this map type on the iPhone or iPad. Here are the steps you have to perform:
- Connect your iPhone to your computer.
- Start iTunes
- Select the iPhone in iTunes
- Switch to the "Apps" tab
- Under "File Sharing" in the list of apps select "myTracks"
- Add the map layer file
