In 1947 the British Indian Empire was partitioned into the Dominion of Pakistan (which later split into Pakistan and Bangladesh) and the Union of India (later the Republic of India). One result of the partition was that 14 million Hindus, Sikhs and Muslims were forced or decided to leave their ancestral homes and move their families to other countries. It was probably the largest mass migration event in human history.
The 1947 Partition Archive is documenting and sharing eye witness accounts of individuals affected by the Partition of British India in 1947. These individual stories of post-partition migration can be viewed on an interactive map. The map allows you to access oral histories of pre-Partition life, post-Partition migration and the ensuing life changes brought about by this migration.
If you select an individual marker on the 1947 Partition Archive Map you can click through to read the individual accounts of living through the partition. The markers on the maps, indicating the individual mapped histories, can be filtered by where the individuals migrated from or where they migrated to.

A few years ago Onformative developed an algorithm, called GoogleFaces, that scans Google Maps satellite imagery looking for patterns in the landscape that we might recognize as resembling human faces.
Terrapattern has taken this idea of detecting patterns in aerial imagery and developed it into something that is actually very useful. Using deep learning machine vision techniques Terrapattern is able to accept a user input (a selected area on a satellite map) and search for other locations which look the same.
For example, if you click on a golf course sand trap on the aerial map Terrapattern will instantly find other locations with golf course sand traps. Click on a stretch of a nice river bank with tree cover and you will be shown other locations where Terrapattern recognizes the same patterns in the imagery.
At the moment Terrapattern only works for Pittsburgh, San Francisco, New York and Detroit. However other cities are coming soon. The Terrapattern about page has other examples that you might want to try searching for, such as baseball diamonds, airplanes or solar panels. Part of the fun of Terrapattern however is just clicking on the map to see how quickly it finds other similar looking locations.
That 'about' page also includes a lengthy 'How it Works' explanation of the neural network behind Terrapattern.

For the next thirty days you can follow actor and performance artist Shia LaBeouf on a real-time interactive map. If you want you can even pick LaBeouf up and take him wherever you want.
#TAKEMEANYWHERE shows LaBeouf's journey so far and his current position. Every day he, and his two fellow travelers, are tweeting the co-ordinates of a location and the first person to arrive can then take them anywhere that they want.
LeBeouf's has in the past been criticized for plagiarism in his art and I can't help noticing the similarities between #TAKEMEANYWHERE and my own performance art piece #BendMeOverBackwards.
Earlier this month the Future of Life Institute partnered with NukeMap to create 1100 Declassified U.S. Nuclear Targets, an interactive map showing all U.S. nuclear targets around the world in 1956.
Of course the nuclear arms race didn't end in 1956. In fact the USA, Russia and many other countries around the world have continued to carry on developing their nuclear capabilities. One way of determining who is continuing to test nuclear weapons is by analyzing seismic records. Which is exactly what Blast Map has done.
Blast Map is a map showing underground nuclear tests carried out by countries across the globe since 1963. 1963 was the year the Partial Test Ban Treaty came into force, which prohibited all test detonations of nuclear weapons except underground. Using data from the Northern California Earthquake Data Center the map shows all seismic events which have been determined to be not geological in nature but were instead caused by either quarry blasting or nuclear testing.
Blast Map shows the location of these quarry blasts and nuclear tests around the world. The chart beneath the map shows the magnitude and date of each of the blasts. The chart and map are synchronized together so that the chart automatically updates to reflect the data in the current map view. You can also use the chart to refine the data shown on the map by range of magnitude and date.
The map sidebar provides links to significant nuclear testing events. For example, if you click on the 'Soviet Nuclear Archipelago' link you can view a map and chart view of soviet nuclear testing from 1964-1991. You can read a little more about the significance of these highlighted testing events and how the map was made on this Adventures in Mapping blog post.

Despite all the sterling work by the LOTR Project to create interactive maps of Middle Earth the most mapped fictional landscape in the fantasy world has to be Westeros.
If you don't believe me here is just a selection of some of the Game of Thrones interactive maps that have featured on Maps Mania in the last two years:
- Game of Thrones: The Kings Road Map
- A Map of Ice and Fire
- The Interactive Game of Thrones Map
- The Westeros Map
- Arya's Journey
Jonathan was commissioned by Random House to create the maps for the published novels. While the interactive maps above don't re-use Jonathon's cartography the underlying maps are obviously influenced by his knowledge of the geography of a Game of Thrones.
Now that the sixth season of a Game of Thrones is upon us there has obviously been a rush of new interactive maps appearing on the scene. Of these new maps I'd pick out Collider's Where is Everybody? map as worthy of mention for attempting to do something a little new.
The Collider map is updated after each episode of the HBO drama to show the last known location of each of the characters. It therefore provides a handy guide to keep track of your favorite characters during season six of a Game of Thrones.
Over the last year I've lost more than a few hours browsing through the BFI's interactive map of Britain on Film. The map is an amazing way to step back in time by finding and watching vintage film footage of locations throughout the UK.
Britain on Film contains thousands of vintage films from all over the UK which you can search for by location and then watch for free. This collection of films has just got even larger as the BFI has now added over 750 films, dating from 1900 to 1999, exploring rural life in Britain.
You can search this new collection on the Britain on Film map by selecting the 'Rural Life' link in the map sidebar. All the vintage films from the collection will then be shown on the map by location. Select a marker on the map and you can view the chosen historical film.

The Nice Guys, starring Russell Crowe and Ryan Gosling, is set in 1970's Los Angeles. If you want to re-familiarize yourself with LA in the '70's before seeing the movie then you should take a look at The Nice Guys Map.
This Google Map takes you on a little tour of some of LA's most famous locations, including the Sunset Strip, the Hollywood Sign and Venice Beach. Each of the featured locations is accompanied by photos from 1977 and 2015. This allows you to directly compare the LA of today with the LA of the 1970's and assess how Los Angeles has changed over the last thirty odd years.
In May of last year a group of explorers and scientists traveled down the Okavango Delta in Botswana. The aim of the expedition was to find new species and collect data on the environment of this mighty river.
Thanks to National Geographic's Into the Okavango you can follow the progression of the expedition and explore the Okavango yourself via an interactive map. Into the Okavango is an animated map which shows the paths taken by four of the explorers. The map automatically plays through the whole expedition but you can take control of the map by pressing the pause button and then using your scroll wheel to progress through the map at your own pace.
As well as the paths taken by the four explorers the map shows the location of bird's spotted along the river during the expedition.
The data from the Okavango expedition and data from previous expeditions of the Okavango Delta is available from the Okavango Database and API. You can navigate to the data by using the 'Data' button on the interactive map. The database and API gives you access to data on animal sightings, audio recordings and photographs.
It is possible to query the database and automatically view the results on an interactive map. For example you can enter 'hippo sightings' into the data explorer and view the results automatically output on a Leaflet powered map.
You can now add animated wind layers to your maps thanks to a new API from Windyty.
Windyty is an animated wind forecast map based on NOAA wind data. It allows you to view forecast wind patterns for the next five days on top of an interactive 3d globe. The map includes a number of other animated weather layers (including cloud cover and temperature) and allows you to view animated wind patterns at a number of different altitudes.
The Windyty API allows you to add the same animated weather forecast layers to your own interactive Leaflet.js maps. You can see the API in action and some example source code for adding a Windty layer to a Leaflet map on this Hello World demo map. For now the API is free to use.
If you want to add an animated wind layer to other interactive map platforms then you should have a look at Windy-JS. With Windy-JS Esri has adapted Earth.nullschool.net's original 3d globe of animated wind into a canvas layer which can be added to a variety of mapping APIs.
Esri has created a demo map with Windy-JS, Wind Animation, which allows you to view global wind conditions animated on top of an Esri slippy map.

Mark Evans has used the Google Maps API to create a hypnotic visualization of commuting flows, showing the distances and 'journeys' that American's make to and from work.
Using the ACS Commute Map you can zoom in on any U.S. county and view an animated map showing where people live and work. The maps don't show the actual journeys that commuters make but do give a great sense of how town and city centers suck in commuters from surrounding suburbs.
The data for the maps comes from the American Community Survey. You can learn more about how the map was made from this data on Mark's blog post ACS Commuter Data Visualizations. Mark's ACS Commute Map was originally inspired by Alasdair Rae's mapped visualizations of commuting in the Bay Area.
