I've seen a lot of population heat maps of the USA over the years - so it is nice to come across a Bizarro version of a population heat map, a map that actually shows where people don't live.
Nobody Lives Here maps unpopulated census blocks in the USA, the areas where nobody lives. 4,871,270 census blocks, totaling 4.61 million square kilometers, have no-one living inside them. In other words 47 percent of the USA remains unoccupied.
Nobody Lives Here is not a brilliant online map in itself. It uses the Leaflet platform to visualize a non-interactive map created by Nik Freeman. There is nothing wrong with Nik's map. However it would have been nice to see the interactive version of the map overlaid on an OpenStreetMap of the USA, with a transparency control. This would make it easier for us to find out a little more about the actual locations of the unpopulated areas shown on the map.
The Boston Globe has published an interesting photo that uses the Leaflet mapping platform to provide an interactive graphic of survivors of the bombing of the Boston Marathon.
One year after the tragic bomb explosion at the Boston Marathon, The Boston Globe invited survivors, police, firefighters, EMTs, doctors, nurses and runners back to the finish line on Boylston Street to pose for a group photo.
The resulting One Year, One City photo is a powerful testimony to the resilience of the people of Boston. By using the Leaflet mapping platform the Boston Globe has created an interactive photo which you can pan around and in which you can zoom in on individuals in the picture. You can even click on the people in the photo to learn a little more about their experience during last year's tragic events.
NECN.com has also used the Leaflet platform to create a story map of the Boston Marathon. The map shows the route of the Boston Marathon and includes stories and accounts from the individuals, businesses and schools that are located along the marathon's route.
The One Year Stronger map can be navigated by using the numbers along the bottom of the map. Click on a number and the map pans to a location along the route and loads photos, videos and text that tell the stories of those who live and work along the route of the Boston Marathon.
The London Cycling Campaign has released a Google Maps based election campaign. Elections are due to be held for all 32 London boroughs on the 22nd May and the London Cycling Campaign can help London cyclists identify local cycling issues and e-mail their local electoral candidates.
The Space for Cycling campaign allows you to select a local election ward on a Google Map and view an issue that effects cyclists in the area. After viewing the issue you can then click on the 'Take Action' button to e-mail the local candidates urging them to support the issue.

Spacehopper is another great Street View based geography quiz. The game was built for school kids studying geography but is lots of fun for us slightly older kids as well.
The game presents you with a series of Street View images from locations around the world (with the odd photo thrown in for good measure). The object of the game is to guess the location of the Street View image by clicking on a Google Map. To help you in this task the possible locations are marked on the map with a little red dot.
You get three attempts to get the correct answer to each Street View. If you are struggling you can also ask for clues. The game includes some user settings that allow you to restrict the views shown to various regions around the globe.
Dynamic Holland Shading is a gorgeous looking map that includes dynamic hill shading based on the date and time of day. Move the date and time of day sliders and you can see the hill shading update instantly on the map.
The dynamic hill shading is powered by a combination of MapBox's dynamic hillshading and the SunCalc library.
The F4 Map is another gorgeous map where the shadows on the map display in real-time and reflect the position of the sun, therefore moving throughout the day. The map also includes 3d buildings and trees.
Here's a little navigation tip: use the ctrl key with the up and down arrow keys on your keyboard to change the angle of the map.
In 2009 an earthquake in the Italian city of L'Aquila caused the death of 308 people and damaged many of the town's historically important buildings. Last year the City of L'Aquila released Noi L'Aquila.
Noi L'Aquila is a Google Map where residents of L'Aquila can record their memories of the city. The site also included a Google Earth plugin of L'Aquila visualizing its reconstruction with 3D models.
Now you can also take a virtual walk through L'Aquila in a new custom Street View tour of this historic Italian town. Hello L'Aquila is an amazing interactive virtual tour of the city consisting of more than 400 custom shot Street View panoramas covering the entire historic city center.
Restoration to the roof of the Duomo dell'Aquila
Most of the Street View images on Google Maps in L'Aquila were taken before the 2009 earthquake. This new Street View tour allows you to explore the city in its current state. The new tour even includes Street View images taken inside some of the city's historic buildings, allowing you to see the restoration work being carried out to repair the damage caused by the earthquake.
If you click on the cross in the top right-hand corner of one of the Street View images you can view a Google Map which shows some of the important locations in the city captured in this new custom Street View tour. The yellow icons on the map indicate where you can view indoor Street View panoramas.

The UK's largest supermarket chain Tesco is back once again with its Street View Easter egg competition. #FindTheEggs proved so popular last Easter that Tesco has decided to hold their Street View Easter egg hunt once again this year.
In #FindTheEggs players have to navigate around Street View and collect three of the thousands of eggs that have been hidden on the map. If you find three eggs you can win a 'chocolate prize''. The eggs are very easy to find, especially if you Tweet a link to the game, which rewards you with an egg radar showing you where to find the hidden eggs. There are also 40 golden eggs hidden on the map which could win you a HUDL tablet.
When you find three eggs you can print out a voucher to claim your free chocolate in a Tesco store or, if you shop online with Tesco, you can receive the chocolate with your next shopping order.

People living in North America and much of South America will tonight be able to see a total lunar eclipse (weather permitting). At around 2 am (EDT) the moon will pass through the Earth's shadow and you will be able to see a gorgeous red moon.
Totality will occur in a 78 minute period beginning at about 3 am on the east coast and midnight on the west coast. You can find out the exact time of totality for your location by using Heywhatsthat's Lunar Eclipse Map.
The Lunar Eclipse Map uses two Google Earth plugin maps, viewed side by side. Click on your location on the left-hand map (or share your location when asked). The right-hand map shows the position of the moon during tonight's eclipse. You can use the time control beneath the map to find out when totality occurs.
In the right-hand map you will see the moon passing over two large circles. The outer circle is the Earth's penumbra and the inner circle is the Earth's umbra. When the moon passes through the Earth's penumbra you will see a partial eclipse and totality will occur when the moon passes through the Earth's umbra.
How Much Have We Polluted? is a mapped visualization of global carbon dioxide emissions. The map allows you to view the yearly per capita and total CO2 output of individual countries around the world.
The map includes data from 1960 to 2008, which allows you to view how individual countries are increasing or decreasing their CO2 output. You can even select to compare the outputs of two different countries at once. For example you can compare the reduction of UK carbon dioxide output per capita from 11.16 metric tonnes to 8.52 since 1960, with the increase in U.S. output from 16 to 17.94 metric tonnes.
To fair to Americans the growth in CO2 output in the U.S. actually compares rather favorably to the growth in Qatar over the same period. Since 1960 CO2 output in Qatar has risen from 3.74 to a planet destroying 49.05 metric tonnes per person.
I'm constantly surprised by the imaginative uses developers find for online mapping libraries. I really like this little experiment that uses Neatline to map out the last three lines of W. B. Yeats's poem 'The Song Of Wandering Aengus'.
Neatline is a tool for creating story maps with timelines or text. It is a wonderful tool for creating narrative maps when you have a story to tell that involves text (or a timeline) with a lot of related locations. It appears that you can also use it to map out poetry.
The Song Of Wandering Aengus Map is an experiment in mapping out the last three lines of Yeats's poem. Each consecutive line of the poem is mapped inside the dot above an 'i' in the previous line. Zoom in on the dot above the 'i' in each line and the next line in the poem appears.
It may be only a small experiment but it made me feel like Aengus himself, who dropped a berry in a stream and caught a little silver trout.
