Keys, Signs, and Measurements (Map layer)

Keys, Signs, and Measurements

This layer includes the map's keys (one for symbols, one for determining water depth), latitude and longitude lines, and significant place names. This layer would have been essential for contemporary readers, especially ones with no first hand knowledge of the space represented. By connecting the maps detail with its use of standard European map tropes, readers could contextualize and situate the land depicted in the map.
