Mobile Atlas Creator is a free open source application that runs on Windows, MacOS and Linux. My maps are easily installed by simply copying two files to the correct folders. They may then be viewed on your computer in Mobile Atlas Creator where you can select all of part of the map for export in many different formats. The apps shown below are only a sample of formats that are supported. And you can also send maps to dedicated devices such as a Garmin handheld or Magellan Triton GPS.
All maps include full documentation, written for beginners, including a thirty page tutorial to guide you through each step of installing and using Mobile Atlas Creator.
