Editing
● Tags – normal OSM ones● start_date end_date
– YYYY / YYYY-MM-DD
● Note of source map would be nice
Simple?
● Rabbit hole● Cart before horse?● Gregorian dates.● Vagueness / fuzzy
imho
● OSM way - – good enough is better than perfect.
● Contributors not historical GIS “experts”● Do whatever and let the renderers sort it out!
Future● More Map layers ● Timesliders.● Vector tiles● Better tracing tools
