Hi, is there a way to download the whole planet in one file? We are going on world trip and our route isn’t fix.
I have previously downloaded a single map for Western Europe, but can’t find it now. Is this option still available, or do I need a separate gmapsupp.img file for every country?
I tried to create one by selecting UK and then adding FR/ES/BE/NL, but the file was too big…
(Apologies if this has been asked & answered previously - I looked but couldn’t find it)
You may be able to download it but AFAIK a gmapsupp.img must not be larger than 8GB, so even a well mapped continent might be too much.
I think limit for img is 4GB. Img structure allows for bigger files, bit I don’t know any device which supports sector size greater than 64kB.
Bigger maps should be divided into multiple parts.
FAT16/FAT32 doesn’t allow files bigger than 4 GB and Garmin devices don’t support other file systems.
Anyone…??
I hadn’t seen that, thanks.
Do you know whether, if I put 2 or 3 of these on a Garmin 810 (with different names for each), the device will automatically switch between the different map files?
Or will I have to switch between each one manually depending on where I’m riding?
You can put multiple maps on the SD card.
You have to select the right map manually, depending where you are. Do not select multiple maps covering the same (overlapping boundaries) area at the same time, as routing might not work or even worse things happening.
OK, so I couldn’t have a map for the whole Pyrenees on the card if I already have one for France?
Or do you mean I could have both, but can only select one of them at a time…?
Typically country/region maps overlap at their boundaries and it could well be that the whole Pyrenees are covered by the France map. So in that case you don’t have to switch to the Spanish (or Andorrans :)) map in case you get into Spain or Andorra. But you have to find that out yourself.
You can have both or more on the SD card but only select (activate) once at the same time if there is a chance of overlap.
(You could select Norway and Spain at the same time without any risk - if you want)
If you are talking about the Openfietsmap Europe, they are seamlessly connected to each other. Just rename the gmapsupp.img parts to a different name.img and put them in the same garmin folder and then you can see one big map. If you are talking about the maps from garmin.openstreetmap.nl you need to use Javawa device manager (to rename the maps stored on your device) or javawa GMTK (to maintain/rename the maps stored on your computer).
Yes, it should work correctly. You can enable all maps in GPS and all will be used and displayed simultaneously.
These are parts of a single map, so routing between parts should work correctly, since boundary nodes of a tiles match precisely. Tiles, which are duplicated in multiple maps will be ignored by GPS. There could be some glitches with address search on areas, which are covered by multiple maps. GPS can search for address on wrong part.
I am a little bit torn about what is wrong here.
I am talking about an old rail line that has been abandoned and eventhough the ground structure is still there the bridge is not.
All online iterations at osm.org do not render the bridge which is correct according to the wiki, the map rendered for the garmin does show the bridge. Which is a bit problematic for navigation.
This is the link to the specific feature,
https://www.openstreetmap.org/way/230281927
Should I remove the feature from the data or should it not be rendered?
If the bridge is still there, garmin will render it but will not route because there is no way (or is there a path?)
If there is no bridge at all this way (or at least the tag bridge=yes) should be removed of course. Maybe is railway=historic a better tag?
Let me reiterate,
Het dijklichaam is er nog (I called it the ground structure) het brugdeel is weg.
sorry for the language switch, my civil engineering lingo is somewhat lacking.
So it is very visible there was a bridge once but you cannot cross the water there without jumping far or getting wet feet.
The line itself is tagged this way:
Tags
bridge yes
historic:end_date 1958
historic:operator Maryland and Pennsylvania Railroad
historic:start_date 1901
railway abandoned
tiger:cfcc B11
tiger:county Baltimore, MD:Harford, MD
tiger:name_base Maryland and Pennsylvania RR
so bridge and abandoned are the key tags. This makes it so openstreetmap online does not render the bridge, the as behavior described in the wiki.
On the garmin both the line and the bridge are rendered, dunno about routing for I usually don’t walk with routing on and I’d rather not be routed on a non abandoned rail line anyway 
If an abandoned rail line was converted to a pathway/ trail i’d imagine it needs to be tagged differently anyway.
Hi, change the bridge=yes tag to demolished:bridge=yes, that should remove the bridge from any routeing.
The railway is already tagged abandoned, (demolished could be a better description of the bridge section) so in the absence of any access tag (i.e. foot=yes) will not be routed.

I would recommend to remove bridge=yes because there is no part crossing that stream, demolished:bridge=yes sounds good.
And replace railway=abandoned with railway=dismantled of that part crossing that stream, see https://wiki.openstreetmap.org/wiki/Demolished_Railway
This way, Garmin will not render the bridge nor railway (but we are not rendering for the renderer, dont we? ;))
Yep I do not want to tag for the renderer
Hence my questions and doubts.
I tagged it demolished:bridge=yes and dismantled. I will try in a couple of days to render a small map of that area to see the changes.
This rail thing is rather convoluted to be honest.
I’d say some better definitions are in dire need. There are too many ppl to vested in historical rail lines and I do think that rail lines have impacted surroundings more profoundly then for instance roads. So there is a need to have this info still in the openstreetmap database.
I’d really say look at what’s there and what words mean. But the discussion seems to be more about feelings
disused means to me not used or planned to be used in the foreseeable future. This also means no maintenance plans for that line. ownership of the land preferable still in the hands of an entity that is or has operated rail transport or maybe the state/country
abandoned, ownership is not in the hand of an entity that is or has operated rail transport. There needs to be some sort of rail identifying marks left, for instance at least ! every kilometer a railroad tie, rails, train signals,etc. Also specific rail support buildings, loading docks, stations, etc. You should be able to use this for navigation.
dismantled, most identifying marks have been removed. for instance an embankment can be used for other things so that would not be an identifying mark. And the identifying marks are few and far apart, more then 2 km for instance. Barely to not usable for navigation.
historic, almost impossible to see that there was a rail line in the past, not usable for navigation.
Something like this would make it also easier for renderers to decide what to render and what not.
I Agree, but this discussion should be held in other topics. To be on-topic, abandoned railways are only rendered in the generic map (default mkgmap style) as path:
railway=abandoned [0x0a road_class=0 road_speed=1 resolution 22]
The generic new style does not even render those lines, unless it is accompanied by highway=* (for instance when such line is converted into a cycleway or footway). Both maps do not render dismantled or historic.
