The Sketch of Geography has been entirely annotated and georeferenced with the support of the Pelagios Project. All the annotations are available for download and inspection: you can download them by cloning the related GitHub folder, where the JSON and CSV exports are stored; or directly through Recogito, the geoannotation tool of Pelagios.
The following map has been created with Carto.com by using the data exported from Recogito. Click on one of the places to open the full annotation popup, or simply search for a place name using the bar on the bottom. You can also see the map in fullscreen by clicking on the link icon on the bottom right.
A fully categorized view of the various place types is also available with the same data:
