Tile Providers
We sometimes get complaints about GPS data apparently not matching
the maps implemented in web services tile providers.
Those services have become, years after years, better and better,
their developers successfully fronted numbers of representation
issues, mostly bound to the fact that the tiles are pictures taken
from satellites of flying crafts.
Such pictures are also processed to fit a Earth model that's all
but a perfect sphere.
This implies that some issues can still arise. Take the two following
examples to understand the "problem".
Same data, different tile provider. We see that different tiles
match differently the same plotted data.
Same data, same tile provider, different time. We can see here
that tile providers evolve (improving) in time.
