Maps of the Week

On an average day the Moscow Metro wi-fi network can see up to 70 TB of internet traffic. The Moscow Metro Wi-fi Map is a beautiful mapped visualization of all those wi-fi users as they travel around the city.

By tracking wi-fi users Moscow Metro are able to observe how passengers navigate the Moscow metro system. They can see how passengers travel around the system from the time that they connect to the wi-fi network until they disconnect. Maxima Telecom's animated map shows the movements of passengers connected to Moscow Metro's wi-fi network, over the course of one day.

The Interactive 1811 Plan allows you to explore a vintage map of New York's 1811 grid plan overlaid on top of a modern map of the city. In 1807 the New York state legislature appointed Gouverneur Morris, John Rutherfurd, and Simeon De Witt to devise an orderly street plan for Manhattan. So began the formation of New York's regulated grid street plan.

What I really like about this interactive version of the map is the option to learn about many of the features of New York's original grid plan. If you click on the 'Key Features' button at the top of the map you can explore some of the decisions made in devising the 1811 plan. For example, decisions made about the width of New York's streets, the length and width of blocks, the limited provision of parks and the numbering system of New York's roads.

11.3% of Indians live without electricity. Luckily we have twenty years of night-time satellite imagery to help identify those rural areas of India which don't appear to have electricity, The World Bank and the University of Michigan have collaborated to analyse this satellite data for 600,000 villages across India.

India Lights is an interactive map which shows the results of that analysis. Each yellow dot on the map represents the light output of an Indian village on the date shown in the map timeline. If you zoom in on an Indian district on the map you can also view data on the district's population and its median light output.

At the district level it is possible to filter the map to highlight those villages which have participated in India’s flagship electrification program. If you select one or more of these villages you can then view the village's median light output over time compared to the district's average on the line graph at the bottom of the map.
