What it is, in a few words
A space-time atlas of the Earth
In one line
The world today, or in any year, on one map.
Why it can be trusted
Every border is drawn from a named record, and every layer names its source.
One sentence
A free space-time atlas: the world today, or in any year from 123,000 BC, on one map.
Short paragraph
IntMap is a free space-time atlas of the Earth. Today’s map carries live earthquakes, rain radar and aircraft; set the clock to any date from 123,000 BC and the borders, the city names, the provinces and 166 layers follow, each with its source named. It runs in a browser with no sign-up, and one link reopens exactly what you see.
Long paragraph
IntMap is a free space-time atlas of the Earth: one map for the world as it is now and as it was on any date. For today it carries live earthquakes, rain radar, aircraft, weather warnings and the news placed where it happened. Move the clock anywhere from 123,000 BC and the map moves with it: country borders day by day from CShapes 2.0 (1886–2019) and OpenHistoricalMap (1689–1885), year by year from Cliopatria (Seshat Global History Databank, from 3,400 BC) where those are silent, and from 54 historical snapshots where none of them speaks. Where the records reach, city labels take that year’s names and the provinces are drawn as they were, and both World Wars can be followed day by day. On the same map sit 166 layers — climate, hazards, population, economy, infrastructure and live feeds — and every one names its source; a layer whose source does not describe the chosen date is simply not drawn. A link reopens the same place, date and layers on any device, and the page for teachers shows how to build a lesson on that. Signed in, Atlas, IntMap’s AI assistant, answers on the map itself. IntMap has no ads and no paid plan and is kept running by donations.
Who it is for, and what it is
Who it is for
People who want to see where and when things happen and happened — history and geography learners and teachers, map lovers, and anyone following the news.
What it is
IntMap is a free space-time atlas of the Earth: one map for the world as it is now and as it was on any date.
What it does
For today, the map carries live feeds — earthquakes, rain radar, aircraft, weather warnings. Set the clock to any date from 123,000 BC and the borders, the city names, the provinces and every layer follow, each drawn only from a record that describes that date, with its source named. It opens in a browser, with nothing to install and no account.
How it differs
Unlike live maps, which know only today, and printed or static historical maps, which show the moments someone chose for you, IntMap puts the present and every past date on one clock; unlike GIS tools, it brings the data with it.
Facts
The numbers are read from the app when this page is built. Each layer and each border source is named, with its licence, on the data sources page.

What can be said about it
- Borders for every year, layered by precision: CShapes 2.0 day by day from 1886 to 2019, OpenHistoricalMap from 1689 to 1885, Cliopatria from the Seshat Global History Databank year by year from 3,400 BC where those are silent, and 54 historical snapshots where none of them speaks.
- The map speaks the year’s language: a city label takes the name the city had then where the record holds one — Edo, Constantinople, Stalingrad — and provinces come from the publishers’ records or, where no record speaks, are reconstructed by IntMap from cited laws, gazettes and change lists.
- Both World Wars day by day: the ground each side held, the front lines on the dates the record places them, and the operations under way.
- The present, live: earthquakes, rain radar, aircraft, weather and disaster warnings, the weather forecast, and the news placed where it happened.
- 166 layers — climate, hazards, population, economy, infrastructure, live feeds — each with its source and licence on the Data sources page. A layer whose source does not describe the chosen date is not drawn.
- One link reopens the same place, date and layers on any device; the same map can be embedded on another site.
- Atlas, IntMap’s AI assistant, answers on the map itself — switching layers, moving the camera and the clock — for signed-in users, within a daily limit per account.
- Free, with no ads and no paid plan; running costs are covered by donations. The interface is in 9 languages.
