"Islands"
This layer outlines the coasts of all the land not included in the major landmasses outline, so all of what would be considered “islands,” when the definition of “islands” doesn’t include what were the “continents.” I’m having a tough time determining an appropriate title for this layer, but I think the quotes are somewhat helpful in conveying the uncertainty I have about this label.
Inhabited Spaces
This layer contains the places where people lived, in either permanent or temporary settlements. The settlements represented include both indigenous and colonial presences. A representation of these two type of settlements could give Spanish readers of the map a better sense of what land was still 'available,' and a stronger understanding of the socio-political dynamics at play in different regions.
