What’s new in IntMap
Each line is written when the change is merged. The date is the day the change was recorded.
War maps now colour each place by the front nearest to it over land. Fixed: occupied Soviet land shown Soviet in early 1942, Austria-Hungary shown Allied in summer 1915, France shown German during the Bulge, and Estonia, Lod and Ramla on the wrong side.
Change #1102With unlimited tilt on, dragging to look up past the horizon works again; since the MapLibre 6.13 update it stopped at exactly 90 degrees.
The historical map fixes eight borders: Danzig stays a Free City until 1 September 1939, Bukovina is Romanian (not Hungarian) from November 1918, and Ruthenia (Hungary 1938-44), Istria (Italy 1920-43), Memel, Hlučín and Southern Sakhalin follow their treaties.
New classroom tour: the Second World War, 1939–1945, in seven views on the layer that colours each state by the side that held it — and two war maps return to the gallery (Europe in November 1942, Korea in September 1950).
On phones, the Map tools buttons show their full names again (Distance / area, 3-D volume, Map screenshot).
Tools and simulations moved out of Layers into one Tools menu at the top right (the Map tools sheet on a phone), in four sections: measure & draw, utilities, simulations and analysis. Layers keeps only layers and presets; its search still finds a tool by name.
When Atlas or a link names a route's start or destination, a place that does not match the name is no longer put on the map; the field is left empty instead.
Fixed: the year book, the rise and fall of a polity and Then & now, opened from the Chronos panel, now appear in front of it instead of underneath it.
Settings now take effect the moment you change them (Apply is now Done), and the desktop search box suggests places as you type and ends with Ask Atlas.
New: Today's quest. Each day has its own five-question set of each learn quest, the same for everyone; the year quest starts with today's date in history. Your first finish counts, with your streak and the last seven days, on every device when signed in.
The security page now says how IntMap checks the libraries it sends to your browser against published vulnerabilities. One library, inside two published advisories, has been updated.
Two new classroom tours for history: the opening of China and Japan from Perry's arrival in 1853 to 1900, and the end of the Cold War in Europe from divided Germany in 1985 to the map of 1993. Both print as worksheets.
Share now has a Cite tab: the credit line to put under a published map, a reference in APA, Chicago, SIST 02, BibTeX or RIS, and — on a past date — that day's borders as GeoJSON, every shape with its record, dates and licence.
On a phone, the clock in the sheet now shows the year on the map. Drag it sideways to move through time with the whole map in view; a bubble names who held the map centre then, and your thumb stops where that changes. Atlas can step there too.
Share a year or a country and its own picture comes with it: each of the 114 "world in a year" pages has a card of that year's world, each of the 252 country pages one of the country among its neighbours, and every entry page ends with links to share it.
"Earthquake record here": from a quake pin, the place card or Atlas, see every earthquake the USGS catalogue holds around a place since records began — the largest, the decades, and where this one ranks. The map follows the clock.
Rise and fall — pick any of the 4,448 polities the history map draws (the Mongol Empire, Rome, the Ottomans …): when the map begins and stops drawing it, its drawn area through time by record, the year of its largest extent, and its life as a time-lapse
When you move the clock to a past year, the country borders now appear first and the provinces follow, instead of both arriving late together.
Historical map: no more slivers of Norway in East Greenland in 1933; land the old records’ coastlines left out — the tip of old Istanbul, Üsküdar and many port cities — is drawn under the polity that held it; place timelines show unrecorded years up to today.
Historical map: where an old record stops short of the shore, the land is now drawn up to the same coastline as the base map (OpenStreetMap) — the Bosporus shores at Üsküdar and Beşiktaş are no longer left blank; place timelines say that no record covers the years after 2019.
Atlas can follow one journey through time — "Vienna to Istanbul in 1913 and today" — naming the states the line crosses at each date, in order, with distances, drawn in each state’s colour. The route panel does the same for your route ("Borders that year").
Type a place and a time together in the search box or the command palette — "Kyoto 1600", "Berlin May 1945", "Rome 44 BC". Pick the suggestion and the map flies there and becomes the historical map of that moment. Old names work, and Japanese era years are converted.
The satellite layer now shows the full catalogue even when its upstream is down.
Then and now: compare one place at two times by dragging a divider across the map (with a finger on a phone), share the comparison as a link that opens on the same swipe, and post it as a card with both maps, the years, the place and every source credited.
The About page now opens on a clock: drag it and the same map changes from 3000 BC to the Cold War, each picture a real IntMap screenshot. Below it, three ways in — the world now, the world in any year, and Atlas.
The place card now shows "This place through time": every polity the historical records draw over that point, oldest first, with its span and source, plus the first-level divisions. Press a row to see that era. Atlas answers "who ruled here in 1600?" the same way.
World map by year — 114 pages, from 123,000 BC to 2016, each showing the world on 1 July of that year drawn from the map's own records, the names on it with their sources, what changed and the events of that year
More historical map corrections: the Faroe Islands 1941–44 and East Greenland 1932–35 are Danish; Kerguelen is no longer «French Indochina»; no Okinawa Prefecture 1946–72; Taiwan, Hawaii and Ireland change hands on the right day; Istanbul reads Constantinople.
New for teachers: a unit map of Japan's high-school geography and history, England's key stage 3 and the US C3 Framework, with the maps, tours and quests for each unit, and a one-page handout for schools.
The historical map now draws the northern Kuril Islands as Japanese from 1875 to 1945, Korea as annexed on 29 August 1910 (when the treaty took effect), and the Ryukyu Islands under United States administration from 1946 to 1972 — each outline's card says which treaty decided it.
Historical map errors corrected by history: Greenland 1941–1945 is Denmark's, not the US'; the English Commonwealth, French Fourth Republic, Kenmu Restoration and Xin keep only their own years; Cairo is Ottoman from 1517, China Ming from 1368; old Istanbul is no longer blank.
Press any border on the map, historical or today's, to see where the line comes from: the record and row on each side, who stated its dates, how precise its outline is, the reviews, the licence, and the dossier for IntMap reconstructions. Report it from there, or ask Atlas.
Historical provinces now reach further back in many more countries — e.g. Nigeria from 1961, Turkey from 1957, Thailand from 1947, Russia 1991–2008, British India — rebuilt by IntMap from cited laws; where a line is unknown, today's line is no longer drawn instead.
Change #1021Past-year borders and province lines now look exactly like today's — same dark edging, same colour on the light map, and shared boundaries are drawn once instead of twice.
Latvia's 119 municipalities of 2011–2021 are now drawn on the historical map (before, Latvia had no provinces on any date), and the Philippines' provinces now reach back to 2001 instead of 2020.
Change #1015Japanese boundaries before 1873 now follow the Gregorian dates of their events — the merged Shiga Prefecture begins on 30 October 1872, not a month early — and the province popup says which reviewed date a boundary is drawn from.
Change #1014Historical borders now show the Sudan of 1885–1889 as the Mahdist State rather than British Africa; Britain held no claim there until the reconquest of 1896–98. The card says the outline is the Mahdist State's of 1890, drawn back to 1885.
Change #1009Time-lapse videos no longer lose a frame on a busy computer, and they are written faster — every instant and the final hold are always in the file, each for exactly its share of a second.
Change #998Historical borders no longer name the Emirate of Nejd between its fall in 1891 and Ibn Saud's return in 1902; the shape stays and its card gives both years.
Change #997Historical borders no longer name a polity outside the years history gives it — for example the Khmer Empire after 1431, Malacca after 1511 or the Holy Roman Empire before 962; the shape stays and its card says why.
Change #995Closing the Radius tool (or switching to another tool) now removes its circles, like Distance/area and 3-D volume; use Done to keep them.
Tapping a place, business or facility name on the map now opens its card — the name, Wikipedia and an AI brief — like peaks and rivers.
Turning off a layer no longer hides the historical borders or other map layers that happened to appear at the same moment — for example, the 1890 borders stay on the map after you switch off Historical city populations.
In the Land cover legend you can now click classes to show only them on the map, as with Köppen climates — the rest turns faint grey.
Historical provinces now include IntMap's own reconstructions from cited laws where no published record exists — Russian Empire governorates (1780s–1917), Meiji Japan's prefectures (1871–1890) and the provinces of about 80 countries.
Historical provinces now come from national and research atlases where OpenHistoricalMap has none — Republican China 1912–49, the Russian Empire in 1897, Spanish America 1701–1808, Roman provinces — and present-day provinces now reach Russia, Greenland, Australia and India.
From 1886 the historical map now draws the colonial territories the sovereign-state record leaves out — the Congo Free State, German East Africa, Angola, Greenland under Denmark — from OpenHistoricalMap, up to 1923.
Where historians record that a border followed a river or a wall — the Roman Danube and Rhine frontiers, Hadrian's Wall, the Yalu after 1627, the Portuguese–Castilian rivers — the historical map now draws it along the real river or wall instead of a coarse straight line.
The compass button has a cleaner look — one slim needle, red to the north, on a thin ring.
The compare window now stays fully on screen on every side, resizing from its top edge no longer drags it around, and its time badge shows one label when both maps are at the same moment.
City names are now sized by importance, like Google Earth — capitals and major cities larger, towns smaller — and the bigger city keeps its name where two would overlap.
The year rail beside the closed Chronos button can now be dragged or scrolled to any year, not only to its tick marks.
In Learn quests, the year is now hidden everywhere it appears while you guess, and tapping your answer no longer opens a news story under it.
Change #978Learn quests: find cities on the map or guess the year of a day in history with the year hidden, answered on the map. A challenge link gives a whole class the same questions.
Change #973The widget board's monitors card is now Watched places, place alerts use the same test as your watches, and Country watch lists only that country's headlines.
New: This week on Earth — every week's large earthquakes (USGS) and natural events (NASA EONET) on a page of their own with a feed, each opening the map where and when it happened.
World events, On this day and the year book now read one index of dated events, each with its source and the precision of its date. The events list follows the map's clock, and the forecast has one Play button.
The resize cursor now shows along the whole edge of the compare window, and the data studio waits for the map to finish loading instead of asking you to switch views.
While you guess a year in Learn quests, the screen-reader narration no longer reads out the answer, and the year slider is labelled correctly.
A press room page now collects what to quote, the facts and where they come from, and the logo and screenshots to download, for anyone writing about IntMap.
The place profile and «Here, now» are now one card. Long-press the map ▸ About the place shows what the map knows about a point and what is happening there now.
Moving the time slider now redraws the day/night boundary promptly on slow devices too — a rough picture at once, the exact one moments later.
The Library keeps everything you make of a map in one place — saved maps, your own drawn maps, tours and Atlas answers — on every device; publish a collection and others can play its tours.
New layer “Historical city populations”: city sizes stated by Chandler and Modelski (Reba et al. 2016), 3700 BC – AD 2000, follow the time machine, China, India, the Americas and Africa included. Each figure shows its year and source, never interpolated.
Historical borders now combine their records by precision and add Seshat's Cliopatria (year by year from 3400 BC): far less of the map is blank, and polities appear in the year they began.
The Tutorial in Settings now plays as a tour, built from the example maps, in the same player as the classroom tours. Each step has words and a question.
Data studio — drop a spreadsheet (CSV, TSV, Excel or pasted) that names countries or cities, and IntMap finds the place column, colours the map by any column, hands it to analysis, and publishes it as a link that needs no account and stores nothing on a server.
Country pages — one page for each of 252 countries and territories that opens the map on it, with its population density, the historical maps of its region and its open data
A country's time-series chart, its AI research and the map screenshot now each go through one path — and the screenshot carries the legends and data credits.
The compare window can now be resized from any edge or corner, with the resize cursor showing where you can grab it.
Atlas finds the right tool more often when a request uses a phrase rather than a single word.
While Atlas works, its progress now appears in one place, the work list in the Atlas panel, with the plan inside it; the map shows a small Atlas pill only when that list is out of sight.
Earthquakes, events, facilities, companies, volcanoes and places now link to one another, and Atlas can follow those links.
Watch places: saved places now report new earthquakes, alerts, volcano activity and news nearby, and remember what you have already read.
The weekly volcano report now says plainly when its publisher blocks automated reading, instead of failing without a word.
A command palette opens with Ctrl/Cmd+K: one box for actions, layers, places, companies, examples and Atlas. Company maps now show where each company operates, read from the land.
Tour builder: add the current map as a step, write narration and a question, and share the whole tour as one link.
Teachers can build their own tours from the teachers page, and the history and organisation pages are linked from every page and from Settings.
An example gallery in the app (now 16 example maps), and pages on reading the news on a map and embedding maps in articles.
New status page, IntMap now: this device, the layers that could not be drawn and why, and last night’s check of every data source.
A new "This page's connections" view in Settings lists who this page actually contacted and checks it against the privacy page. New security page and private way to report a vulnerability.
Place search: each result is one place (choosing a capital no longer jumps to the country), and Enter goes to the first result.
The radiation dispersion check against Fukushima 2011 now uses the published release timeline and a regional wind nest: correlation rose from 0.28 to 0.46.
New volcanic-ash simulation (what if it erupted now), and the dispersion and pandemic models now show a range of outcomes.
Classroom tours can be printed as worksheets: each step becomes a map image with its legend and sources, ready to hand out.
New pages for newsrooms, schools and research groups, an enquiry form, and a page on supporting IntMap.
Shared links that carry many layers open more reliably, and a time-zone layer that fails now says why.
The radiation dispersion model is now checked against the measured Fukushima 2011 fallout, and the result is published.
Your data: see and download everything your account holds, and save places to your account.
Place profile: everything the map knows about one point on one card — name, area, elevation, layer values, local time, sunrise and sunset.
Status page now shows each data source's record over every nightly check (up to 90 nights), and the data-sources lists say how often each source answered.
Stories: follow one news story across days. Related events are grouped, played back on a timeline and map, measured for spread, and shared with a ?story= link.
News by country: the pulse of each country’s news, a daily report, and internet outages beside the headlines.
On phones every panel that floats over the map can now be reached with a finger, above the sheet and the credits.
On phones: "Here and now" shows weather, earthquakes, news and a place's former names in one card without sending your exact position, and IntMap can receive photos shared from the share sheet.
On phones, cards the map shows sit above the sheet, and reading a card raises the sheet.
This day in history: pick a calendar day and see the events the map records for it, as a card, in Atlas, and on a page for each day.
Entry pages for historical maps by region and date, in English and Japanese, so a search can find the map of a place on a day.
Map postcard: save the current map as one PNG for posting, legend and sources included; shared links now carry a title and a summary.
My Maps: draw pins, lines and areas, name them, add notes, save them in this browser, share them with a link, measure them, analyze them, and export GeoJSON or GeoPackage.
New country-indicators layer (national statistics on one layer) and a yearbook of the world for any year.
Read the map in words (Alt+R, with screen-reader support), and save maps for offline use where the supplier’s terms allow it.
Historical maps now show where the record is missing (hatched) and tell disputed, overlapping and seam areas apart.
A first visit opens on a full-screen map, and start-up downloads fell from 13.4 MB to 3.9 MB.
For developers: control an embedded map from your page with a small script, and use a static open-data API of the datasets whose licenses allow redistribution.
The company atlas and national elections now refresh every week and say how up to date they are.
Report a map error with its place, view and year, get a reply under a reference number, and see fixes in a public corrections log.
Collections are now workspaces: save the map itself to your account, and publish a collection as a read-only link that others can copy into their own places.
Atlas can now work through what-if scenarios, change over a period, and whether a correlation between two things holds.
Atlas answers become research notes you can keep, reproduce, compare with today and hand on, and Atlas can now diagnose itself.
Atlas briefings: share a research note as a link. Anyone can open it without an account and read the answer, its sources and the map as it ended.
Atlas before you sign in: see the free allowance and how Atlas answers before asking, and example questions follow the date on the map.
On phones, the sheet moves out of the way when you pick a place or the map moves, so the place card stays in view.
Change #904A redesigned phone layout: one sheet and one control group cover the map instead of many panels (the share of the map covered fell from 45% to 14%).
Change #901Export a time-lapse as a video (MP4 or WebM) and a comparison as one PNG, with the year, the sources and a link burned in.
The privacy notice now lists the live ship-tracking connection that uses your own AIS key.
Phones load the map in stages, fetching each resource only when it is needed.
Faster start on phones: work the first screen does not need is no longer done at start-up.
Only your own language is downloaded at start-up, and a language that fails to load now says so.
The NATO legend now counts the members drawn for the date shown (it said 32 for 1985), and several legend titles show in the right language.
Icons are now crisp line drawings instead of emoji, and look the same on every device.
Historical maps: eight errors in names and dates were fixed at the rule that caused them, including colonial-era country names and re-established prefectures.
Stricter security on every page: no inline script may run unless it is the exact one IntMap ships.
Classroom tours: a lesson as a sequence of maps, each step with narration and a question for students, played full-screen with Next and Back.
The map no longer switches on data layers by default, and the basic display (borders, labels, terrain) is no longer counted as a layer.
Atlas now shows its plan on the map: the goal, each step and its status. Tap a step to see what it drew.
