OSM alternative Worldwide Basemap

[mpistora]

I'm looking for a map similar to the pre-installed "Worldwide DEM Basemap", but a bit more detailed. I would like to use it on a plane to keep track of where I am. The OSM-based Garmin maps I found are too detailed for this purpose. I don't want to install individual countries. There are also maps for all of Europe, but they are larger than 10 GB.

You can choose the map of Europe that suits you in the installation version on computer,
also install the MapSource program.

On the map in MapSource, mark the route to the target point, then click the route and select the option
"Select maps near the route", an img file will be created that can be used on the device
containing map areas only along the flight route.

MapSource should be in a version that allows you to send the map file to your computer's disk,
new devices are not fully supported by MapSource.

If there is a problem with finding the right version of MapSource, I can send such a version.

In Base Camp, you can manually select map areas along the route to be sent to the device,
obtaining a similar effect as in MapSource.

I believe mpistora is looking for a single worldwide basemap replacement that is slightly more detailed than the standard Garmin worldwide basemap.

I think so too, but I also think that he will not be flying in two different directions at the same time,
using the proposed solution will significantly reduce the size of the map.
If he specified which map objects he is willing to give up I can significantly r
educe the size of the map of Europe (maybe not every one map) but it is possible.

Any Garmin basemap replacement would need to be worldwide.

The user @mpistor justified the search for a map more detailed than the Worldwide DEM Basemap map
with several reasons:

he does not want to install detailed maps of individual countries

the map of Europe is too large - so it is not about a map of the entire world.

Installing maps of entire areas of several countries on the flight route may involve a large size (GB)
which I want to avoid.

We do not know whether tracking the flight route will be one-time or frequent, as well as whether there will be flights in different directions, the given solution can be used sporadically as well as for tracking more often on different flight routes.

Completely missing the point.

The Garmin basemap is worldwide.

If you want to replace the Garmin basemap with a different map, it also must be worldwide.

Nobody mentioned changing the base map.

The base map does not have to be a map of the World, it is enough that it covers the area of ​​the detailed map.

There does not even have to be a base map in the device, then there may be problems
(long time of drawing the map) at a zoom above 5 km.

Nobody mentioned changing the base map.

Did you read the title of the thread?

It is difficult to be guided by the title of the thread if the text mentions the map Worldwide DEM Basemap.
