Once you have downloaded a PDF you can print out the map and spend hours of fun coloring it in.

While you enjoy coloring your downloaded maps of U.S. cities be sure to thank OpenStreetMap for the map data (CC-BY-SA).

The Ordnance Survey Blog has links to the 11 UK maps which you can download as PDF files.

The United Colours of Vancouver

You can learn a lot about Vancouver from its maps. For example this Vancouver Building Heights map can teach you where all of Vancouver's tallest buildings are concentrated. It can even tell you the height of every building in the city

Building footprints on the Vancouver Building Heights map are coloured to represent the height of the building. If you want to know the exact height of an individual building in the city then you just need to mouse-over the building footprint on the map.

Vancouver's building footprints can also be coloured by the age of the buildings. This Vancouver Building Age Map shows the age of all the buildings in the city.

The data for the building ages is from the City of Vancouver's Open Data Catalogue and the map tiles were created using ArcGIS and TileMill. The property lots of the oldest buildings are shaded yellow on the map. The youngest buildings are shaded blue.

Once you know the size of a building and its age it is also possible to estimate a building's energy usage. The Energy Explorer is a set of tools for exploring community energy use in Vancouver. The site aims to encourage a vision of a more sustainable city through the use of renewable energy resources. As part of this aim the Energy Explorer includes two interactive maps visualizing the city's current energy use and its potential for renewable energy resources.

The Home Energy Map provides a visualization of current energy use by Vancouver households. Building footprints on the map are coloured to show their estimated energy usage based on the age of the building and its size. Vancouver citizens can therefore use the map to see how much energy they use and compare it to the estimated energy usage of their neighbors.

We don't need to stop at building age, building height and estimated energy usage. We can also find out the value of Vancouver's land parcels. The Vancouver Land Prices Heat Map visualizes the price of Vancouver parcels of land based on the 2014 BC assessment data from tax reports. Land parcels on the map are coloured to reflect the price per square foot of the property.

The map shows that many of Vancouver's most expensive properties are concentrated in the Downtown, West End and Fairview neighborhoods. The map also shows that land prices tend to get cheaper the further you move east in the city. If you select a building lot on the map you can view the exact price per square foot for the property.

The Pixel Map Wizard

Pixelmap from Amcharts is an easy to use tool for creating a pixellated map. Using the tool you can create a map in a matter of seconds and download the map as an image, SVG or HTML file.

Pixelmap includes a number of options which allow you to adjust the size and shape of the pixels used in your finished map. The tool also includes options to color individual countries on the map and to choose the color of the world's oceans. You can also zoom and pan the map to create a pixel map for a selected region of the world.

When you have completed your map design you have the choice to download your map as an image file, as an SVG or as an HTML file.

Mapping the Champions League

Geolic has created two interactive maps which show the distribution by country of players who have appeared in EUFA Champion League finals and the distribution of players who have scored goals in Champion League finals.

Champions League Finals in Maps allows you to view the overall number of players each country has had in Champions League finals. Players from Germany and Spain dominate the map, which is hardly surprising as teams from those two countries have also made the most appearances in the finals of the competition.

The map also allows you to pick any year to view the geographical distribution of players who featured in that year's Champions League final. A second map allows you to view the geographical distribution of players who have actually scored goals in the finals of the Champions League.

Mapping a Game of Basketball

NBA Movement is an animated map which plots a passage of play during the Clippers vs Rockets game on May 12th, 2015.

The map uses data from stats.nba.com. Savvas Tjortjoglou has written up a nice tutorial explaining how you can extract the data from play by play movement animations at stats.nba.com. Jorge Sanz has used this tutorial to get the data for the Clippers vs Rockets game.

The data has been mapped and animated using CartoDB's Torque library. The result is a neat animated map which tracks the players of both teams and the ball during one passage of play during the game.

Player heatmaps are very popular in lots of different sports. In the NBA shooting heatmaps can be used to reveal the individual shooting patterns of different players, showing where they are most dangerous on the court. 2014-15 NBA Regular Season : Field Goal Shooting Patterns is a CartoDB map that shows the shooting heatmaps of five players during the 2014-15 season.

Using the map you can view and compare the shooting heatmaps of Stephen Curry, Anthony Davis, James Harden, LaMarcus Aldridge and LeBron James.

It is also possible to use CartoDB's Torque library to create animated heatmaps. For example, this CartoDB Referee Map is an animated heatmap of one soccer referee's movements during a soccer game. The map uses CartoDB's Torque library to animate the referee's movements over the ninety minutes of the match. If you pause the animation and move the timeline to the beginning of the game you can see the full GPS track of the referee over the ninety minutes without the heatmap layer.

Mapping Uber in New York

FiveThirtyEight has published data on over 4.5 million Uber pickups in New York City from April to September 2014. The data also includes data on 10 other for-hire vehicle companies.

Bill Morris has used the data to create an animated map of Uber pickups for the week beginning April 1st 2014. One week of Uber Pickups in 15 Seconds uses CartoDB's Torque engine to visualize the patterns of pickups by time and day. The timeline shows the day currently being visualized on the map but not the time of day. However you can spot a significant drop in pickups at certain times every day. My guess is that this drop-off in pickups is during the very early hours of each morning.

Bill's map shows the temporal patterns in Uber pick-ups in New York City. Another map, by Mapbox's Eric Fischer, shows the geographical distribution of the pickups for the whole six months worth of data. Uber NYC Pickups, Apr-Sep 2014 provides a dot density view of all Uber pickups across the city.

Both maps are great initial visualizations of the data obtained by FiveThirtyEight. It will be interesting to see what other maps are created with this data. For example, I'd like to see Eric's map with some New York demographic data layers. It would be interesting to see if there is any correlation between the number of pickups and the average income levels in a neighborhood.

Another interesting visualization would be a comparison of the Uber pickups data with the yellow taxi data for the same six months. The NYC Taxi & Limousine Commission has released the data for all completed yellow taxi and green cab trips between January 1, 2014 and June 30, 2015, so it is possible to make a map with both sets of data.

Patterns of Longitude

Enter your address into A Place to Departure and you can create your very own work of art. The artwork that you create is a pattern generated from your latitude and longitude. This means that no-one else in the whole world will have the same pattern as you.

A Place to Departure is an experiment in creating Location Based Generative Art. The main focus of this art project was the creation of two art installations, one in Beijing, China, and the other in Sao Paulo, Brazil. The installations consisted of a large interactive glass screen placed in each city. When a person touched the glass screen in Beijing or Sao Paulo the glass screen in the other city would vibrate at the equivalent point on the glass.

The result was that people in either city could feel the interactions of people on the other side of the world.

The glass screens were accompanied by patterns made from wood. These patterns were created by algorithms based on the geographic coordinates of where the installations were located. The A Place to Departure website includes a Google Map which allows you to create your own location based pattern by simply typing in an address.

Mapping New York's Homeless

I'm not sure what to make about this crowd-sourced map of New York's homeless citizens. The NYC Map the Homeless app encourages people to take photos of homeless people in New York City and share the results on the NYC Map the Homeless Google Map.

A few weeks ago Google banned a map of refugee centers in Germany because it was seen as encouraging attacks on migrants in the country. I assume that the creators of this homeless spotting app don't want to encourage attacks on homeless people in New York. However I do find it slightly disturbing that they are encouraging people to take photos of the homeless. This seems unnecessarily degrading for those forced to live on the streets and potentially dangerous for those taking the pictures.

NYC Map the Homeless argue that the data gathered will help the 'authorities ... quickly identify locations of concern and act in a timely manner'. I'd like to think that there are better ways to help the homeless of New York than this app.

Mapping LA's 20 Year Mobility Plan

The Los Angeles City Council has released a new Mobility Plan designed to decrease the use of cars and improve conditions for the city's cyclists and pedestrians. The plan includes hundreds of miles of new bike lanes, bus lanes and other road redesigns.

The LA Times has mapped out proposals in the plan so that you can see the affect on the city's roads. The How will L.A.'s transit overhaul affect you? map shows the proposed bike lanes, dedicated bus lanes and streets where the council plans to restrict parking.

You can search the map by location. You can also filter the results on the map to view changes which will affect cycling, buses and parking.

Mapping UK Immigration Levels

Yesterday the UK government released figures showing that net migration (the balance between immigration and emigration) in the last year has reached its highest ever level of 330,000.

1 in 8 UK residents were born overseas. In my neighborhood in East London over half the population was born outside the UK. Four other London boroughs also have populations where over 50% of the residents were born overseas.

The Office of National Statistics has released an interactive map which allows you to view the percentage of the population in each local authority area who were born outside the UK. The What are migration levels like in your area? map uses data from the 2014 Population Survey to present a choropleth view of migrant levels in each local authority area.

You can search the map by Local Authority area. If you mouse-over an area on the map you can view the percentage of the population who were born overseas.
