Map Your Location Data with Shifted Maps

Shifted Maps is an interesting visualization of personal location data. If you use the Moves mobile application you can use Shifted Maps to view an interactive map of your own location data.

Before testing your own location data you might want to view the demo map to get a feel for how Shifted Maps works. Each location visited in your location data is shown as a zoomed-in circular map inset and the map insets are scaled to show the amount of the time spent there. The size of each circle's circumference line represents the relative number of visits.

You can refine the data shown on the map by date by using the timeline control in the map menu. You can also explore the data by geo-spatial position, travel time, and frequency of movement by using the three icon buttons in the menu. These three buttons rearrange the circular inset maps to provide different visualizations of the location data.

The first button rearranges the map circles to visualize the places visited based on their geographic positions. The middle button provides a temporal view, rearranging the circles according to the average time it takes to travel from one location to another. The third button creates a frequency of movement visualization, places with a frequent connection are shown closer to each other than places with a less frequent connection.

Create Your Own Maps with Map Channels

If you're looking for a quick and easy way to create a Google Map then you should give Maps Channels a whirl.

With Map Channels v5 you can create a free interactive map which you can then embed on your own website or blog. Despite being quick and easy to use version 5 of Maps Channels comes with a lot of interesting options.

You can see what is possible with Map Channels on this user created map of Petra in Jordan. The map includes markers, photos and Street View imagery of some of the important archaeologically sites within Petra. If you click on any of the map markers you can view the location with Google's new panoramic imagery of Petra, with an automatically rotating Street View of the location

Map Channels many interesting features include the ability to create an editable map, add places and select Street Views for your added places. Maps can also be set to allow contributions from visitors. You can easily include road directions on a Maps Channels map, which can also be bookmarked and printed by the map's users.

The Google Maps API recently withdrew the Panoramio photo layer. Map Channels still includes this option so you can also add a Panoramio layer to your map, to show nearby photos from Google's photo sharing website.

Another interesting feature in Map Channels v5 is the option to link to other Map Channels projects directly from your map. For example, you can add markers to your map which then links to a Maps Channels Local Map, Dual Map and/or a Tour Map.

Glasgow Construction Projects in 3D

What better way to celebrate St Andrew's Day than with a 3D map of Glasgow. Glasgow in the 21st Century has seen a number of high profile building projects and the city is continuing with a number of ambitious construction projects. You can view Glasgow's current construction plans on this new 3D map of the city.

Lately I've been working a lot with OSM Buidings. In particluar I've been using Webkid's tutorial on creating Interactive 3D Maps With OSMBuildings. The tutorial explains how the Berliner Morgenpost used OSM Buildings to create its excellent Berlin's neue Skyline interactive map of Berlin's new skyscrapers.

Stuart MacMillan has also used Webkid's tutorial to help develop a 3D Map of Glasgow Construction Projects. Stuart's 3D map of Glasgow shows some of the city's current construction plans (highlighted in different colors on the map).

Stuart has added an option for anybody to submit their own GeoJSON building polygons to the map. If you click on the 'Empty GeoJSON' button you will be sent to where you can create a building polygon of a Glasgow construction project and then grab the resulting GeoJSON file for the completed building polygon.

The Geopolitical Maps of the Week

The Oregonian has used CartoDB's Torque library to create an animated map of terrorism deaths around the world from 2001-2014. Deaths by Terrorism, 2001-2014 shows worldwide fatal terrorist attacks by month.

There is always the danger with Torque powered animated maps that the data just becomes flashing dots on a map. On its own the animated data over time on this map probably wouldn't reveal much about international terrorism. However the Oregonian has also added a couple of other data layers to the map to provide some much needed context.

The 'Deaths by Country' option adds a choropleth layer to the map, showing the number of terrorism deaths by country around the world. The 'Narrative' option allows you to select each individual terrorist attacks on the map to view a summary about the attack and the original news source for the data.

123 countries around the world are currently involved in territorial disputes. For example, the USA is currently involved in territorial disputes with Cuba, the Bahamas, Haiti, Colombia, Nicaragua, Jamaica, Honduras, the Marshall Islands and Tokelau.

A World of Disputed Territories is an interactive map of all the territories around the world whose ownership is contested by more than one country. By selecting a country on the map you can view all its current territorial disputes and who those disputes are with.

After you select a country on the map all the country's currently disputed territories are colored yellow on the map and all the other countries involved in the dispute(s) are colored blue. Select one of the disputed territories (colored yellow) and you can read a brief report on the nature of the dispute and the countries involved.

Global Migration Data maps migration patterns around the world on a 3D globe. The map shows the number of migrants to and from each country and which countries they traveled to or from. The data comes from the UN Dept of Economic & Social Affairs for the years 1990, 2000, 2010 and 2013.

Global Migration Data is very easy to use. Simply select a country from the drop-down menu. You can then select to view either inbound or outbound migration for your chosen country. The time-line at the bottom of the map allows you to select which year's migration data you wish to visualize on the globe.

The 3D globe shows the spatial patterns of migration, visualizing which countries around the world migrants traveled to or from for your selected country. The dashboard below the map shows the total number of migrants (inbound or outbound depending on your current choice) and the number of countries migrants are from or the number of countries migrants moved to.

Exploring Namibia by Satellite

A Little Landsat Tour is an interesting story map which uses Landsat 8 imagery to explore some of the geological and man-made features which can be found in Namibia.

As you scroll through the tour the map flies across Namibia to highlight a number of geologically interesting locations, such as river valleys, deserts, dry lakes and volcanoes. The tour also explores how man has impacted on the environment, zooming in on diamond mines, ranches, center-pivot irrigated farms and evidence of slash and burn farming.

The map was made by Charlie Loyd, who works on satellite imagery for Mapbox. Judging by the URL I'm guessing that the map was made in 2013 from Landsat imagery captured that same year. The story map format of the tour is based on Mapbox's Scroll Driven Navigation template.

Mapping Global Road Fatalities

According to the World Health Organization the USA has poor road safety laws. It fails to meet the WHO's requirements for good drink driving laws, for speed limit laws, for helmet laws and for seat belt and child seat belt laws. This might be why the United States has almost twice as many road fatalities per population as nearly every Western European country.

Death on the Roads is an interactive map showing the number of road deaths and the status of road laws in countries around the world. The map uses data from the WHO Global Status Report on Road Safety 2015 to present a choropleth view of global road deaths and road safety laws.

If you select a country on the map you can view the number of road deaths per 100,000 people. Using the tabs at the top of the map you can also view how well each country meets the WHO's requirements for different road safety laws.

Dublin Story Maps

Storymap Ltd have created two interactive maps of Dublin, in which local people tell their stories about the city and their own lives. Dubline - Storymap presents a route across Dublin, from College Green to Kilmainham. Along & around the route are a number of map markers representing the interesting stories of Dublin and its people.

By clicking on the markers you can watch videos in which Dubliners will regale you with fascinating stories about some of the locations along the route. For example you can hear about Dutch Billy, the most abused statue in Dublin, a gunfight between students and a fellow of Trinity College, and how an elephant came to die on Essex Street.

Storymap is a charming Google Map that captures the personality of Dublin city through Ireland’s age-old tradition of storytelling, presenting a vision of Dublin as told through its stories and storytellers.

If you are ever lucky enough to visit Dublin you can be sure that the locals will talk your ear off. Storymap takes advantage of the Dubliners' love of telling a good tale by presenting the city through the stories of the local people. 

The map itself is a collection of videos in which Dubliners tell the stories of locations around the city. The stories include the strange tale of the first cat to fly across the Irish Sea.

The Terrorism Timelapse Map

The Oregonian has used CartoDB's Torque library to create an animated map of terrorism deaths around the world from 2001-2014. Deaths by Terrorism, 2001-2014 shows worldwide fatal terrorist attacks by month.

On its own the animated map layer might have been a little crass, reducing thousands of deaths to little flashing dots on a map. However the Oregonian has also added a couple of other data layers to the map to provide some much needed context.

The 'Deaths by Country' option adds a choropleth layer to the map, showing the number of terrorism deaths by country around the world. The 'Narrative' option allows you to select each individual terrorist attacks on the map to view a summary about the attack and the original news source for the data.

The Thanksgiving Flight Map

Google Trends has published an animated map showing people traveling across the USA to get to their Thanksgiving Day dinners. US Thanksgiving on Google Flights uses CartoDB's Torque library to animate domestic and international air travel on the eve of Thanksgiving booked through Google Flights.

You can use the playback control to navigate through the whole of yesterday's plane journeys. As the day plays out you can see a clear pattern of flights starting on the east coast in the early hours, spreading to the whole country, until the latter hours of the day when flights emanating from the east of the country die down, while flights from the west coast carry on until the early hours of today.

The flight markers on the map are colored to represent the different airlines.

The Battles of Narvik

Germany invaded Norway in April 1940. The northern city of Narvik quickly became an important strategic target for both the Allies and the Nazi. Narvik's ice-free harbour in the North Atlantic provided perfect access by rail to the iron ore mines in Kiruna, Sweden. Both sides were keen to secure this iron supply for themselves and, by doing so, denying it to the enemy.

The Battles of Narvik is a web-documentary commemorating the 75th anniversary of the German invasion of Norway and the battle over the Norwegian town of Narvik. The documentary explores both the land and sea battles between the Nazis and the Allies in their struggle to secure Narvik.

Evidence of the sea battles can still be found deep in the Ofotfjord. On April 10th, 1940 the British Royal Navy and the Kriegsmarine both lost two destroyers each. Three days later the British managed to sink another three German destroyers. Most of these shipwrecks remain at the bottom of the Ofotfjord to this day.

Narvik is a popular destination for scuba divers as it provides a unique opportunity to explore these German and British wrecks from World War II. To help divers locate the wrecks The Battles of Narvik includes a Google Map showing the locations of both the British and German destroyers now lying at the bottom of the Ofotfjord.

You can learn more about the invasion of Norway and the Allies resistance on Invasjonen av Norge. Norway and its allies managed to continue the fight against the German invasion in April 1940 for 62 days. However Germany's invasion of France in May caused Norway's allies to withdraw and the Norwegian government was forced to seek exile in London.

Invasjonen av Norge is a really nicely designed story map recounting the Norwegian War in 1940. The history of the campaign is told in chronological order. As you scroll through the chronology in the map side-panel the map automatically updates to show the relevant location.
