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

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).

Hi Gerd, Karl, Thanks for your interesting information. @Gerd, I've tried to generate a map with a resolution of 23. During the processing, I've received a lot of messages like "SEVERE (TypeReader): 63430028.osm.pbf: Type 0x07 min-res:24 will not be written with level 0 at resolution 23 in style file lines, line 215 -> routing may not work". This was due to some rules in the "lines" file of the default style. I modified them from "resolution 24" to "resolution 23" as my goal was to keep all ways and to obtain a routable map. The issue was solved. Looking at the result, I can see that details (useless for me like buildings, POI, ...) have disappeared and the map size is now 142MB instead of 242MB for Belgium. Excellent !! The strange thing is that the result seems less accurate. It looks like some nodes have been removed. For example, a roundabout is drawn as a triangle. Is it possible? @Karl, Here is a description of the TopoActive map (West part): TopoActive Europe 2020.20 South West 2.92 GB (3,139,764,224 bytes) Andorra, Belgium, France, Iceland, Ireland, Italy, Liechtenstein, Luxembourg, Malta, Monaco, Netherlands, Portugal, San Marino, Spain, Switzerland, United Kingdom, Vatican City, Albania, Bosnia and Herzegovina, Croatia, Greece, Kosovo , Macedonia, Montenegro, Serbia, Slovenia If I take all these countries in Geofabrik, the total size is 10,4GB. So the ratio is 3.56. From my example of Belgium above, the ratio was 2.8 but I need to examine what can still be removed to gain some more space. Anyway, I'm interested in your 'optimized' style.

Hi Pierre, yes, it is possible and expected. Resolution 23 means a raster of ~4.8 m. I assume the Garmin map contains no buildings. Does it allow address search?

Hi Pierre, If you use resolution 24 you can remove details like buildings and use high values for filters like --reduce-point-density. You may decide to not render polygons like landuse=farmland|meadow|grass and so on. Reg. address search and buildings: I asked about the Garmin map. If they don't render buildings this will save a lot of bytes. Address search (--housenumbers) also adds data. Next thing to look at is the DEM data and / or contour lines.

@Karl, Here is a description of the TopoActive map (West part): TopoActive Europe 2020.20 South West 2.92 GB (3,139,764,224 bytes) Andorra, Belgium, France, Iceland, Ireland, Italy, Liechtenstein, Luxembourg, Malta, Monaco, Netherlands, Portugal, San Marino, Spain, Switzerland, United Kingdom, Vatican City, Albania, Bosnia and Herzegovina, Croatia, Greece, Kosovo , Macedonia, Montenegro, Serbia, Slovenia If I take all these countries in Geofabrik, the total size is 10,4GB. So the ratio is 3.56. From my example of Belgium above, the ratio was 2.8 but I need to examine what can still be removed to gain some more space. Anyway, I'm interested in your 'optimized' style.
Thanks again, Pierre

I have tried creating a minimal style. This lowers the data to about 75 % or my normal set up.

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).

Hi Karl, I see you mention that automotive routing is disabled in the TopoActive Europe Map on your GPSMAP 66st, are you able to use automotive routing with your maps created with mkgmap? The reason I ask is I received a new Etrex 32x as a present and when I went online to check for any firmware updates I saw one of the changes from version 2.5 to 2.6 (for the Etrex 32x) was that automotive routing was disabled for OSM maps (https://www8.garmin.com/support/download_details.jsp?id=14889#Instruct). For this reason I did not update the firmware, the only other change was to text translations so would not affect the operation of the GPS. I did not want to update to try if automotive routing was disabled on all maps based on OSM data and then brick the device trying to go back to an old firmware if it was.

Hi. I have seen that firmware change. I was considering getting an Etrex 32x, but decided to wait till it was clear if it is related to Garmin's maps or all OSM-based maps. Unfortunately i don't know yet. On the GPSMAP 66st (with software 6.00) i can use automotive routing for mkgmap made maps, it works very well.

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 ?

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!
