Turning Merge Lines on attempts to merge features together to simplify a map haven’t noticed it making that much of a difference. Optimization options include Reduce Point Density with the Douglas-Peuckel algorithm to shrink the map size and speed up display default is 2.6, and higher values simplify even more (mkgmap’s author recommends 10 as a good value). The other General options don’t seem to make that much of a difference. Description, which identifies the mapset in the GPS unit.Map ID Number, which should be a unique integer value between 6559999 to avoid conflicts with other maps.The most important variables in the General Options section are: Hold the mouse cursor over each of the variable options to see pop-up help text describing their use, derived from mkgmap’s original documentation. Use the button at upper-right to select the. You’ll need to have Java 1.6 installed on your system which you can check at the Java website. I’ve finally gotten around to fixing some of these issues, and now have a newer version of the GUI available download it here (it comes with a copy of the mkgmap compiler), and unzip it into the folder of your choice. It didn’t allow use of any of mkgmap’s more advanced options.It assigned every compiled map the same default Map ID number (63240001.img), which meant that you could only use one compiled map at a time without having map conflicts.It required the compiler to be in the same directory as the data file.I wrote a simple Windows GUI for it a while back, but it wasn’t very good: It’s command-line only, which can make it a pain to use. I covered the free map compiler mkgmap in part 13, which converts OpenStreetMap data files (.osm) and Polish map files (.mp) to Garmin’s binary.
