Last week we looked at how Europeana Labs has used Leaflet.js to create a simple interactive interface for viewing medieval manuscripts. Prophesies About the Papacy allows you to use Leaflet's panning and zooming controls to explore the illustrations and text in the Vaticinia de Summis Pontificibus, a series of prophetic manuscripts dating from the 14th century.
Europeana Labs are not the only developers to use Leaflet to provide a simple interface for exploring images. The Rijksmuseum also uses Leaflet to allow visitors to explore the works of the famous Dutch painter Rembrandt in close detail. The Rijksmuseum's dedicated Rembrandt web page includes a number of the Dutch master's paintings, all of which can be explored in detail using a Leaflet powered interactive image viewer.
The Minneapolis Institute of Art has also used Leaflet to provide an interface to view works of art in its extensive collection. For example this Leaflet map of Christ Driving the Money Changers from the Temple allows you to examine El Greco's painting in all its stunning detail, including the portraits of four other Renaissance painters in the lower right-hand corner.
Of course image viewers created with Leaflet don't have to be confined to presenting the paintings of famous artists. The Getty Museum has used Leaflet to provide a way of exploring the beautiful designs which can be found in Roman mosaics. The Getty's Roman Mosaics website includes a Leaflet map showing the original locations of the Roman mosaics in its collections.
Leaflet wasn't used just for the map. If you click through on the links provided in each mosaic's marker on the map you can actually explore the mosaics themselves on their own individual Leaflet image viewer.
Gunma GIS Geek has also used the Leaflet mapping platform to create interactive maps from a couple of famous Japanese pilgrimage mandalas. Pilgrimage mandalas are paintings which provide a panoramic view of temple and shrine sites.
The first map on Temple Pilgrimage Mandala is of the Nachi Pilgrimage Mandala. This 16th–17th century hanging scroll depicts the Nachi Shrine on the Kii Peninsula in Japan. The painting represents the journey of two pilgrims (the couple clothed in white) as they enter the scene (bottom right) and take a circuitous route through the temple complex to the Nachi shrine.
75 years ago, on the 7th December 1941, the Japanese launched a surprise attack on the U.S. naval base at Pearl Harbor. Around 2,400 Americans were killed and 1,178 wounded in the attack. The attack directly led to the USA entering into World War II.
Japanese developer Hidenori Watanave has mapped eyewitness reports of the attack on a 3D interactive map of Oahu island in Hawaii. The 1941 Project allows you to read testimony of the attack on Pearl Harbor from actual eyewitnesses of the attack, as documented in Katrina Luksovsky's book, 'Ford Island December 7, 1941'.
The map was created using the Cesium WebGL virtual globe library. The 1941 Project also includes links to Hidenori Watanave's other 3d mapping projects. These include the Hiroshima Archive, a 3d map of eyewitness accounts of the Hiroshima nuclear bomb, the Nagasaki Archive, eyewitness accounts of the bombing of Nagasaki, and the Battle of Okinawa, eyewitness accounts of the 1945 Battle of Okinawa.

Jonah Adkins has created a U.S.Avengers interactive map which can help you find your local Marvel superhero. U.S.Avengers is a new Marvel comic book series which features an America-themed team of Avengers. Using Jonah's map you can discover which of thees superheroes is from your U.S, state.
io9 has been keeping tabs on Marvel's promotional cover art releases for the new U.S.Avengers comic. Marvel has released one promotional cover for each U.S. state. Each of these individual state covers assigns an individual Avenger hero to the featured state. So io9 has been able to work out the Avenger superhero for all 50 states.
Jonah has used this information to create his U.S.Avengers Map, which shows the Avenger superhero for every state. Each state includes a map label which shows the name of the local Avenger superhero. You can even mouse-over these superhero labels to view a picture of the hero,
Jonah used Mapbox Studio to create his custom comic styled map. The map uses four different background images to create the comic half-tone type effect.

The Vaticinia de Summis Pontificibus are a series of prophetic manuscripts, dating from the 14th century. The manuscripts depict a succession of different popes from history, in which the popes are illustrated in various alliances with the Antichrist.
The European Union's Europeana Labs has used the Leaflet mapping platform to create an interactive presentation of the University of Fribour's copy of the manuscript. Prophesies About the Papacy allows you to use Leaflet's panning and zooming controls to explore the illustrations and text in this ancient manuscript.
Europeana Labs has written up a how-to guide on how the map was created with the Leaflet and Europeana API. Building a rich media experience with the Europeana API and IIIF explains how Leaflet can be used to display Europeana records through a simple call to the Europeana API.
In September Nathan Rosenquist released an interactive map which allows New Yorkers to submit photographs of cars parked illegally in bike lanes. carsinbikelanes.nyc displays the photos of these reported vehicles on an interactive map. It also prominently displays the licence plates of the obstructive cars.
As well as creating this interactive car-shaming map of New York Nathan also open-sourced the code behind the project on GitHub.
Cars in Bike Lanes Boston has used Nathan's code to create a similar map fo Boston cyclists. This means that cyclists in Boston can now submit details and photographs of offending vehicles to their own interactive map of cars illegally obstructing bike lanes.

A couple of years ago Eric Odenheimer made a very popular static map which was reported as showing you what country you would see if you stood on the beach anywhere in North, South or Central America and could see all the way across the ocean.
What Odenheimer's map actually shows you is the country across the ocean which is on an equivalent latitude. Andy Woodruff was inspired by Odenheimer's map to create a series of static maps which actually show you what is actually across the ocean if you look perpendicular to the coast.
In Beyond the Sea Andy takes into account that the coastline actually bends and turns and faces in lots of different directions and that the world is round. Therefore what country is across the ocean perpendicular to the coast depends on where you are standing on this twisting coastline. Andy's explanation about the maps goes into a lot more detail about how he calculated these great circle lines for different points from the world's coastlines.
Esri UK was in turn inspired by Andy Woodruff's maps to create an interactive map of Coastal Views from the United Kingdom. Esri's map draws lines from different points along the UK coast showing which country lies across the ocean if you look perpendicular to the coastline.
The advantage of using an interactive map is that Esri has been able to add a little more information to their map. If you click on any of the lines drawn on the map the name of the country across the ocean is revealed, as is the number of miles away the country actually is.

The Tile Exporter helps you to make 3d models of your favorite locations around the world. Enter a location into the Tile Exporter and it will generate the OBJ file that will allow you to print out a model of the location on a 3d printer.
Tile Exporter uses OpenStreetMap data to generate the 3d models. This means that the accuracy of the model will depend on the accuracy of the map and building height data of OSM. Luckily this is pretty accurate for most locations around the world. The Mapzen powered generation tool also means that you can preview the model on your computer screen before attempting to print it out on a 3d printer.
Have you ever dreamed of owning your own 3d scale model of the Grand Canyon or the Matterhorn? Thanks to the Terrainator you now can. The Terrainator is very similar in design to Tile Exporter. The main difference is that the Terrainator is used to create 3d models of interesting terrain rather than 3d buildings.
The Terrainator uses Google Maps to help you select your favorite area of terrain. It then creates an accurate scale model and uploads it to Shapeways, ready for 3d printing. The cost of the model depends on the volume of material required to make the model. Flatter models are therefore cheaper than mountainous areas, although they are much less fun. It is also possible to purchase the created STL files from Terrainator if you want to print out your own terrain model yourself.
The Terrainator is limited to areas of the world where it has accurate terrain data.

The Catalina Eco Marathon is a grueling race through some pretty tough mountainous terrain. It isn't easy to convey just how how hard the Catalina Eco Marathon can be to run but Mapbox have given it a good try with their interactive map of the course.
The Catalina Eco Marathon Map uses MapboxGL's new extrude property to overlay a 3d elevation chart over the course of the marathon route. The elevation chart visualizes just how steep parts of the course actually are. The 3d elevation route is itself interactive and you can mouse-over sections of the course to find out the elevation at any point.
The map includes an inset panel which displays a 2d elevation chart of the course. You can interactive with this chart to find out the elevation and distance of different parts of the course. The 2d chart is also synchronized to the map, which means that the map view also updates to show the location of the selected part of the marathon course.
The countries of the world are connected in many ways. There are the transportation links that allow us to travel from one country to another. There are the global communication networks which allow us to speak with people on the other side of the world. There are also transnational pipelines and electricity grids which allow countries to import and export power.
Exploring the World of Connectivity shows some of the massive infrastructure networks that make possible global communication, travel and energy exchange. The infrastructure networks displayed on the map are based on those outlined in Parag Khanna’s book 'Connectography - Mapping the Future of Global Civilization'.
The mapped networks are categorized into the three main areas of transportation, energy and communication. These different categories can be isolated on the map by using the filters in the map sidebar. Each of the three categories are subdivided into individual infrastructure networks which can also be selected using the filters in the map sidebar.
If you are visiting London this winter you can look forward to ice skating at Somerset House, the Christmas market on the South Bank, the Christmas tree in Trafalgar Square and the Christmas lights decorating Oxford Streets.
London Covered by glh Hotels is a nice interactive map of things that you can see and do in London this winter. It is also a clever way of marketing glh's London Hotels. The map shows the locations of London's special winter events, ice skating rinks and winter markets. It also shows the location of some of the best stores to visit to complete your Christmas shopping.
As you browse the map you can add any of the points of interest that you fancy to your own personal itinerary. You can, of course, also book your stay in any of the featured glh hotels.
The map itself is a nice custom designed map with neat illustrations of the featured points of interest. The custom map has been made interactive using the Mapplic mapping library. Mapplic is a mapping library which is particular effective in creating interactive maps from your own custom made maps or images.
