I'm wondering whether the early Spanish data was deliberately excluded from the visualization or whether it was actually missing from the data set.
This is data collated by the US Navy (and later discovered by Matthew Maury), but the linked articles doesn't state where the Navy sourced the earlier shipping logs from. Since the US Navy was "officialy" established in 1775, the earlier data cannot have been collected by the US Navy? The visualizations start off in 1750, 25 years before the US Navy existed.
Maybe the Spanish data wasn't available because it wasn't openly shared at the time. Remember at this time such missions were highly secret - a race for resources and distant lands.
I would be interested to know the answer to this. Even if it is just a sample, it is indeed a fascinating look back into a brave new world of exploration and colonialization by Europeans across the globe.
