The world today, or in any year, on one map.
Today’s map carries live earthquakes, rain radar and aircraft. Move the clock to any date from 123,000 BC and the borders follow — and, where the records reach, that year’s city names and provinces.
Every border is drawn from a named record, and every layer names its source.

Three ways in
Each one opens the real map, in the state described.
The world now
Today’s map with live rain radar and aircraft. Earthquakes, weather warnings and the news placed where it happened are in Layers and News.

Open the map at a past date and move the clock: the borders change with it, and where the records reach, so do the city names and the provinces. Each border is drawn from a named record.

Atlas, IntMap’s AI assistant, answers on the map: it switches layers on and moves the camera and the clock. Open the map and choose Atlas in the side bar — on a phone, type into the field at the top. Its suggested questions follow the place and the date on screen. Asking needs a free account, with a daily limit.
Open the map and ask AtlasWhat makes it different
Now and then, on one clock
Move the clock and the map moves with it: country borders day by day from CShapes 2.0 from 1886 to 2019 and from OpenHistoricalMap from 1689 to 1885, year by year from Cliopatria (Seshat Global History Databank, from 3,400 BC) on the ground those leave, and from 54 historical snapshots where none of them speaks — and the countries panel shows the figures for that year where its source has them.
Honest about what it knows
IntMap has 166 layers, and the Data sources page names every organisation whose data they show. Set the clock to a date a source does not describe and that layer is not drawn — the map tells you so, instead of showing today’s data under an old date.
Ask the map in words
Signed in, you can ask Atlas, IntMap’s AI assistant, in plain language. It answers on the map itself — turning layers on, moving the camera and the clock.
