did anybody ever try to store Google maps or OSM (OpenStreetMaps) on embedded MCUs (Arduino, EV3, Raspi)and later process them offline ?
I mean: store a map area on SD,
show a small section on a TFT (I have a 220x176)
and if one passes a GEO coordinate offline (latt, long) the program marks this spot on the TFT screen?
Would or might this work?
I am using Arduino Dues, but programming in C/C++ the code should be quite similar on EV3 or Raspi as well.
