[mkgmap-dev] Garmin Topo Europe map

Sun Dec 27 19:59:39 GMT 2020

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
