Other “geo” things

Got some spare reading time? Allan Mustard recommends The Address Book by Deirdre Mask. The book looks at the complex and sometimes hidden stories behind street names and their power to name, to hide, to decide who counts, who doesn’t – and why.
Ian Dickson talked with Ben Hinze about ‘Ambient Maps’, a company mapping noise and air pollution in Australian and New Zealand major cities and regions. By combining a number of inputs and models they can produce predictions of air traffic noise, road traffic noise, rail noise, air quality and future road noise impacts.
Alan McConchie tweeted a link to Kenneth Field’s new book Thematic Mapping: 101 Inspiring Ways to Visualise Empirical Data. Using 101 maps, graphs, charts, and plots of the 2016 United States presidential election data, the book explores the rich diversity of thematic mapping and the visual representation of data.
As a test, Anthony Stephens likes to ask ‘anybody under 30 years old who lives in the city’ to name the suburb directly to the north of where they live. Anthony is the owner of ‘The Map Shop’ in Adelaide (Australia) and in an ABC article he discusses the future of paper maps in a world of satnav.
