From looking at the source code of mission planner it looks as if it uses
gmap to download map tiles (normal images) and then stitches them
together to create full map.
However, From my understanding of
gmap, it does not download map tiles by default rather saves all offline maps in form of a
data.gmdb file. Can someone please explain to me how does it use
gmap to download map images instead of saving it in
Can we replicate the idea in other open source projects i.e downloading map tiles and using it offline?
data.gmdb is just a SQLite database, use a SQLite database viewer to extract the images
