- Historical researchers and teachers making source-based maps
- Worth noticing
- Attested, approximate, and conjectural borders use solid, dashed, and dotted lines; routes connect known stops without claiming an exact path.
Field notes
A CSV needs Place, Latitude, and Longitude; Date, Source, Category, and Notes are optional, and importing a new CSV replaces previously imported places. GeoJSON adds lines and polygons, while the border editor allows certainty to vary by section. Some coastlines follow modern Natural Earth data, and the page cautions that coastlines have moved and should be checked against sources.
