Questions for a new front end GUI for MkgMap
by Frank Bijnen 21 Feb '25

Dear all, Sorry if this is the wrong place to ask. Background: I have developed a front end gui for mkgmap, written in Delphi (Rad 12 CE) that will run on Windows 64 bit. It allows to download the files needed and create maps from them using splitter/mkgmap. Typical files to download are the bounds-latest.zip, sea-latest.zip from www.thkukuk and pbf files from download.geofabrik.de. Initially this was meant only for private use, to update my own devices. But now I would like to share this program on a Github repository, including source code and an installer. Ideally the installer would also download and install the latest versions of mkgmap and splitter. I have no commercial interest, it will be free software. Externals used: - mkgmap/splitter - osmconvert/osmfilter (slightly modified versions to allow compiling with CBuilder) - java of course - style files (The standard style files, openfietsmap lite and hiking, modified version of abandoned project motoroute.de) - geonames cities500 - sea-latest.zip, bounds-latest.zip Questions: - Am I allowed to publish this kind of project? If yes: Are there any rules I should obey? - Are there any persons/organisations I should ask permission? @Thorsten Kukuk. What is your opinion? - The installer would need the latest version of mkgmap and splitter. Is there a way to find this info, or is there a link to the 'latest' version? Thanks in advance, Frank P.S. Happy to provide more info, source code, current installer etc.

Does mkgmap:unpaved work?
by Thorsten Kukuk 20 Feb '25

Hi, My Garmin Edge 1050 shows now for every tour in the statistic, how many percent of the roads are paved and how many unpaved. For my OSM maps, it shows always 100% paved. I even changed that value so that all ways should be unpaved. (I hope it doesn't matter that the doc says "mkgmap:unpaved=yes" while all examples and my style are using "mkgmap:unpaved=1". Does anybody knows if this flag is really working/set correct or has example maps where it is working? Except the original Garmin NT maps, that ones are correct. Thanks, Thorsten

Update on missing POI Labels on some devices and some questions...

* As I posted here <https://www.mkgmap.org.uk/pipermail/mkgmap-dev/2024q4/034350.html>on 2024.12.01, I was having issues with POIs not displaying labels for some garmin devices (specifically the XT2 and Tread) when generating /img files using mp file input to mkgmap. I did some exploration and discovered this (maybe well known but not by me): ** * Each device model displays POIs differently (i.e., type 0x100 does not show the same thing). There seems to be no consistency across models (Felix echoed this in a follow-up post). * Each model displays labels for each POI type differently (some show no label, others show small vs big text). There seems to be no consistency across models. * I attempted to use the custom "[_point]" feature of the mp files and mkgmap but the custom point bitmaps only work for some garmins. Even then, it didn't help with my missing [poi] labels. * Prior to the labels not working on the XT2 and Tread units, I always used the 0x1400 POI code type for my labels. With a lot of cross-model experimentation I discovered a single POI code (0x1E00) will display large text on all garmin models I was able to test with (Montana 6XX and 7XX, XT, XT2, Tread). I have no idea if this POI code will work with all garmins that support custom maps. Questions: * Are these issues with each model behaving differently with respect to POI types well-known? If so, how are they gotten around by (OSM) map builders? How can a single map be built that has POIs and labels that are consistent across more than one device. What am I missing? * How does OSM handle this? I presume that an OSM map generated for an area works on all garmin devices? I will admit that I don't know what the OSM map limitations are across garmin models. Does the JOSN model allow the devices POI maps to be loaded on a per-map basis? If I were to switch to JOSN model for mkgmap input, could I get around all the device limitations I am running into with the mp file format? Can someone recommend a good tutorial on getting up to speed on generating JOSN for simple map input to mkgmap? * OSM uses the JOSM model to feed mkgmap. Does that model allow for more flexibility and control than the "mp" input file model? I presume the MP file format is obsolete. * Is there any better documentation for the MPO format than the CGPSMAPPER pdf file floating around on the internet? * Can anyone recommend either a different website or people whom I may contact for further help with any of this? Any and all help is appreciated. *

Feature Request

Hi, Is it possible to add the feature to output all elements like: Test map mkgmap has a built-in feature to make a map containing all(?) possible points, lines and polygons. This is useful to see how different Garmin types looks like. export BASE_LAT=50.0 export BASE_LONG=10.0 java -jar mkgmap.jar test-map:all-elements but instead of producing an .img file I'm looking to produce an .osm file in order to be able to manipulate it... Cheers Joao

Or if anyone knows how to apply a TYP file to that img file please let me know... Cheers Joao
