The Cesspits of San Francisco


NBC say that many San Francisco streets have conditions which are comparable to some of the worst slums in the world. An NBC Bay Area Investigation surveyed over 150 streets and discovered a number of San Francisco's streets are littered with trash, discarded needles and even human feces.

In Diseased Streets you can view an interactive map visualizing the results of NBC's investigation. The map shows the overall sanitation score given to each street by NBC. You can also filter the map to show individual scores for the amounts of trash, needles or feces found on each street. If you click on a street on the map you can see exactly how many needles, feces and trash NBC found on that street.

According to NBC over the years reports of needles and human waste to 311 have steadily risen. Therefore it looks like the conditions on San Francisco's streets are getting worse not better. In fact you often get cleaner conditions in some of the world's worst slums. People who live in slums tend to try to keep them as sanitary as possible. Because San Francisco's homeless are continually moved on there is no need for them to worry about sanitation.

The USA - A Democracy for Sale


Saudi Arabia wants to build two nuclear reactors. This might seem surprising for a country with lots of oil and a seemingly unlimited potential for solar energy. So why does Saudi Arabia want to go nuclear? Obviously Saudi Arabia is keen to join the ever growing list of countries that own their own nuclear weapons. Perhaps that is why it wants two nuclear reactor and is also reluctant to deny that it might use them to enrich uranium for nuclear weapons.

Luckily nuclear non-proliferation treaties mean that the USA can't sell nuclear technology to Saudi Arabia. Unfortunately the Trump administration is pursuing a deal to try to sell the Saudi's the two nuclear reactors anyway.

You might wonder why the Americans would want to help another brutal dictatorship get nuclear weapons. There are two possible reasons. One is that this could be just another example of Trump's 'America First' policy. America just grabbing the money while it can and screwing the consequences for the whole world. Another reason could be the influence that Saudi Arabia has over American legislators.

We all know that in American politics money talks. So let's take a look at Middle East Lobbying: The Influence Game. Al-Monitor's interactive map reveals the amount of money that Middle East countries spend on lobbying the American government. Every year Al-Monitor reveals how much money Middle-East countries spend on lobbying and also assess how successful each country has been in its lobbying.

The kings of Middle-East lobbying are of course Saudi Arabia. Last year Saudi Arabia spent $14 million in lobbying American politicians. Obviously just spending that money doesn't mean that they were successful in buying any influence. To determine if the USA's democracy is really for sale we would have to see if the Saudi's actually achieved anything, such as becoming Trump's first official visit or successfully buying nuclear technology.

The Queen's Travel Scratch Map


I've visited 10 countries. Which is 3.4% of the countries in the world. If you are interested in which countries I've been to then you can visit my personal travel scratch pad.

However, rather than looking at my travel map, you can have far more fun creating your own map of all the countries that you have seen. Scratch the World is a fun little interactive map which you can use to boast about all the places you have visited around the world. Just click on all the countries you have been to and Scratch the World will mark them off, work out the total number of countries you have been to and tell you what percentage of the world's countries you have visited.

You can even get a unique URL which you can use to share with your friends when you want to boast about your global travels.

Mind you, no matter how much of the world you have seen, the Queen's travel map is still much better than yours. After all she has visited hundreds more countries than you (if I had my own plane, train, and ocean liner I would have also have visited more countries than you).

The Travels of Queen Elizabeth II is an interactive map of every country the Queen has visited since 1953. In total the Queen has visited 110 countries. This is 43% of the countries featured on Scratch the World. Therefore there are still quite a few countries for the Queen to visit.

If you are in anyway interested in the global travels of the Queen then you can use her travel map to view all the countries she has visited by decade and by type of visit (state or commonwealth visit (royal beach holiday is missing from the available options)).

Europe isn't where you think it is


Africa, Europe and South America aren't where you think they are. According to John M Nelson lots of us think that Europe and Africa are a lot further south than they really are and that South America is further west than it really is.

In Misconceptions Nelson explores these three commonly held geographical misconceptions. Obviously whether he is correct or not depends on how good your mental map of the world actually is. Where he is right, as always, is in his immaculate cartography. I particularly like how his maps seamlessly transition from the style of a hand-drawn map sketched in a school exercise book to a full-sized globe in your grown-up office or library.

If you are also impressed by the realistic looking globes then you can find out how to create them in Globification - Turn Your Maps into Plausibly Realistic Globes. The tutorial even includes some downloadable images which you can use as the background for your own interactive globes.

Pennsylvania's Non-Gerrymandered Map


One consequence of redrawing electoral districts to try to squeeze all the voters of one political party into one district is that you end up with some very oddly shaped districts. Back in 2014 the Washington Post mapped America’s most gerrymandered congressional districts. One conclusion that they reached from mapping loads of oddly shaped districts was that you can get a good idea of how gerrymandered a district is by how irregular its shape is.

You might want to think about this irregular shape rule when reading the New York Times' article The New Pennsylvania House Districts Are In. We Review the Mapmakers’ Choices. Yesterday the Pennsylvania Supreme Court issued a new congressional map to replace the one gerrymandered by Pennsylvania Republicans.

The Time's article includes a series of maps which allow you to compare the Republican gerrymandered districts with the Supreme Court's redrawn districts. When switching between the two maps for each district you can look out for irregular shapes where boundary lines are snaking out to capture neighborhoods that don't seem to be a natural fit. The Supreme Court's district maps do seem to be much more compact than those drawn by the Republicans. The Supreme Court maps don't have as many "squiggles and offshoots and tentacle-looking protuberances" that are common to gerrymandered electoral districts.

The Washington Post map of America's most gerrymandered districts gives the old Pennsylvania congressional districts gerrymander scores mostly in the 80's & 90's. Scores that indicate the districts have been highly gerrymandered to favor one political party over another. The fact that the Pennsylvania Supreme Court has redrawn a much fairer map doesn't appear to be very good news for the Republicans. However we will have to wait until the elections later this year to see which party really wins in each new Pennsylvania district.

The World's News - 2017


2017 was a momentous year. It began with the swearing in of Donald Trump as the 45th President of the United States. It ended with the USA withdrawing from the UN's New York Declaration, a policy adopted unanimously by 193 states to help improve the fate of refugees and immigrants. You can read more about the major events of last year in World 2017.

World 2017 is a summary of the major news, sports events and scientific discoveries that happened last year. It provides an overview of the global political, economic and social events which shaped 2017. As you scroll through World 2017 you progress chronologically through the year. As you progress an interactive globe rotates and shows you the locations of major events around the world, while the scrolling sidebar provides a summary of each of these global events.

Under the hood World 2017 is using Klokan Technologies' WebGL Earth. WebGL Earth is an open-source virtual globe. The WebGL Earth JavaScript API is based on the popular Leaflet JavaScript API and is therefore relatively simple to use, especially if you have experience of using the Leaflet mapping library.

The Carpooling Map of Europe


BlaBlaCar is an online carpooling service. It connects passengers looking to make a journey with car drivers who plan to take that route. Passenger and driver then share the cost of the trip. BlaBlaCar operates in 21 countries, most of which are in Europe.

BlaBlaCar has around 60 million users and it matches lots of passengers with car drivers willing to give lifts. For example last month 39,752 BlaBlaCar drivers passed through Paris on route to other locations. You can view how many rides passed by your location with BlaBlaCar's Destinations map.

Enter a location into the map and you can view all the trips which passed nearby in the last month. The map uses Mapbox's pitch feature to provide a neat oblique overview of the extent of all the journeys that passed through your selected location.

The Over Emotional Map of New York


Crying in Public is a crowd-sourced map of New York's emotions. A place to share those New York moments when everything that could go wrong has gone wrong.

Sign in to Crying in Public and you can mark those New York locations where you too have felt overpowering emotions. To show what kind of emotional episode you experienced at your selected location you can choose from a number of different emojis. For example a broken heart emoji can be used to show the location of a break-up, a flame emoji can be used to show a spot where you were once fired or a green face can be used to mark a place where you have vomited.

The map was created with the Leaflet mapping library but uses the Google Street View Image API to show a static Street View image of emotional locations shown on the map.

If you like emojis with your maps then you might also like Air New Zealand's new #EmojiJourney map.

The Noise Map of Berlin 2018


Every five years, the Berlin Senate Department for the Environment, Transport and Climate Protection calculates the noise levels of every house in Berlin. The Berliner Morgenpost has used the data to create an interactive map showing road, public transit, airport and industrial noise throughout the city.

If you hover over any part of the Berlin Noise Map you can view the noise levels at that location. The information includes the recorded decibel levels for both day & night-time and a breakdown of the decibel levels from road and transit noise (and planes where relevant). The map does not include ambient neighborhood noise, for example from nearby pubs and nightclubs.

The map doesn't reveal too many surprises. As you might expect properties on the flight path into and out of Tegel Airport are among the noisiest. Elsewhere it seems that the busier the road you live on then the noisier it is (which makes sense when you're measuring road noise).

Emoji Map Search


Air New Zealand has invented a new way to explore New Zealand. Just Tweet your favorite emojis to Air New Zealand and they will send you a personal interactive map of fun places to visit in New Zealand.

If you use the #EmojiJourney hashtag and three emojis in a Tweet then Air New Zealand will send you a link to a Google Map of New Zealand featuring recommended things for you to see and do - based on your choice of emojis. For example if you send a wine glass emoji, a bike emoji and a ski emoji you will be sent a link to a map showing wineries, great places to cycle and places to ski.

If you don't want to use Twitter you can just go to the #EmojiJourney map and search the tourist map of New Zealand by selecting your favorite emojis. You can even get your own emoji map by simply appending emoji symbols to the end of the map's URL.


Emojis can also be used as a simple universal non-written location coding system. For example, What3Emojis is a revolutionary new way of addressing the entire world using the only common language of the entire human race, the emoji.

With What3Emojis the Earth is divided into 4m x 4m squares which are randomly assigned a unique three-emoji combination. If you want to share your location with someone else all you need to do is send them the three emojis assigned to that location. They can then enter the emojis into What3Emojis and be shown that location on the interactive map. Simple!
