Full Europe dem file was 254 Mb. This is 9.23 Mb (like an average basemap). Just a smaller country has a 4.5 Mb dem.
It couldn't be Eurasia dem in my opinion.

Okay!
(But what's the difference, because full europe is 25x bigger file, then eurasia? It's "just" data. Hm...)

It's not "just" data. It's what kind* of data. DEM size depends on not only on coverage but also changes** in elevation. Furthermore, there are different level of accuracy. "Basemap" is lowest*** level (try highest zooming and compare) If you parsed the DEM file, you'll understand.
* "kind" includes NASA (raw data) and CGIAR (fixed data). So it's possible to see newer/better DEM to be smaller in CGIAR than NASA.
** data is height field, so mountainous places take more data to encode than flat places.
*** actually, some .fbl (map file) have the lowest/basic DEM data in them. Which only used at lowest zooming (planet view)Last edited by osiris4isis; 4th April 2019 at 10:04 PM.

thank you all for your work. regarding the DEM subject on medianav (4.1.0 sync), and for a guy like me who's really, really dumb, how can I know if the DEM file is working properly? I have the Basemap_Eurasia_CGIAR_2006.06_180504.dem and Full_Europe_CGIAR_Premium_2006.06_170825.dem under CONTENT/DEM
And if it's not, what shoud I do to make it work??
Regards in advance!
