Often I look at a map and wonder when it was created.
How do I figure out the age of an undated world map?
If I have a vector file of world political boundaries, but I am not sure of the date, then what resources can I use to determine the date?
Is there a map service on the web that allows me to enter a date and get a map of world boundaries for that date?
Assuming there is, what process would I use to determine how close the match is?
Are there any rule based systems that are specific to map dates?
