Hi. I am ok with sharing the style, but i was not able to do it until today (planned today or tomorrow). 5 files attached, 4 related to style, 1 to TYP (foskan.txt). Only those 4 style files have changes, compared to the standard. The complete set of files is ./mkgmap-rNNNN/examples/styles/default/ There is nothing fancy nor complex, nor have i played around with the levels yet. For reference i also added my TYP-file, which may help in case you find some type codes which are non standard (there might be a few). The type file is shared and does contain a few things that are not used by the minimal style (don't get confused). Summery of the style, which is based on the default mkgmap example. All changes comments are marked with ## to be able to tell them apart from regular comments given after #. polygons and points do have a lot of disabled information. Buildings, shops, and most of the parking types are disables. lines doesn't have as many changes and probably a few more small waterways (streams, rapids, waterfalls) can be disabled to remove yet a bit of data. note for polygons. Waters and forests are still visible, since it adds information to the map, but if natural objects are not important for you, there is more space to save. i have made one change in lines file to display the road name on tertiary roads instead of the reference. this does make sense in nordic countries, where tertiary roads are usually only referred to with the name. Ski lifts (arealways in general) are set in similar way as railroads. One last thing to mention is that i have updated the inc/address file. Close to the end there is a section in which the mkgmap:phone is updated to show information about which fuels are sold at fuel stations. This is not fully complete for all fuel types but the ones i somehow considered important. Depending on where one is, a few more fuel types can easily be added. A note. The mkgmap:phone seems to be 50 characters maximum, longer data will be truncated and not shown on the device it seems. Regards and happy new year!

Hi Karl,
don't you want to share your minimal style? :)

Hi. A few observations about the TopoActive europe map. (i have it on a GPSMAP 66st).
The map is rendered slower than most custom made maps. Updates occur 2 times per year, but even at those times many changes to OSM are not present. Perhaps they only update some parts yearly. Points lack all kind of additional information which other mappers add (opening hours, region, phone numbers, etc.). One nice thing is colour marked national parks and reserves. Being an outdoor map, it lacks some information about shelters in the wilderness. Routing is possible only for outdoor activities (cycle, walk, hike, direct), automotive routing (car, motorcycle) is disabled.
I have tried creating a minimal style. This lowers the data to about 75 % or my normal set up. But i did not change the level, which i will try :-) Currently I am no way near the compression which TopoActive achieves. Using input data which is about 6,7 GB in pbf format, creates a gmapsupp just below 4 GB for normal and around 3 GB for minimal style. These numbers feels similar to getting France into 1.9 GB from 3.7 GB pbf (geofabrik).
The minimal set up is not very fancy at all, it disables things not wanted. Buildings, shops, most of parkings, and a bit more.
Today i cannot send off any style, but in case that would be of interest let me know and i can share it in a few days (guessing Wednesday or Thursday).
Regards Karl

Hi Pierre,
my first guess would be that the level 0 is at resolution 23 instead of 24.

Hello guys,
I've just discovered the Garmin TopoActive Europe map based on OpenStreetMap data. This map is sold at a price of 50€ or is pre-installed on some new devices. I've just seen it on the device of one of my friends and it looks very good. I'm surprised to see that for West Europe, it takes only 2.8GB and is quite complete (index for search, routable, ...).
For now, I generate my own maps based on your excellent tool but the result is much bigger (1.9GB only for France with probably more details). So, my question is: does anybody have a similar configuration (style files and command line) to obtain a result like the Garmin TopoActive Europe ?
