Azimuthal Equidistant Projections (maps) from Around the World

Meeting Date: 
Wednesday, September 27, 2017 - 7:00pm

Here' s an exercise: Go outside and point to Japan. Done? Yes; Japan is azimuth 330 degrees from CNY, just 30 degrees West of North. A flight from NYC to Tokyo -almost- flies over the North Pole.

Living on a sphere complicates matters. I was pondering this while looking at a Azimuthal Equidistant Projection provided by a Dxpedition to a remote island.

An Azimuthal Equidistant Projection, also known as an Azimuthal Projection Map, has the useful properties that all points on the map are at proportionately correct distances from the center point, and that all points on the map are at the correct azimuth (direction) from the center point.

I developed a series of Azimuthal Equidistant Projections from various parts of the world, revealing how the world "appears" to our fellow hams around the globe. I will present these Projections for your consideration during the September meeting. I hope that you can join us.
