[FRIAM] Great Circle

Sun Sep 19 17:57:38 EDT 2021

Interesting too to get distances for a question I have often asked folks:

Santiago, Chile is on the west coast of South America. Which US city has
the closest value of longitude? often have to remind that longitudes are
the north/south meridians / lines on the globe.

   1. Los Angeles
   2. Houston
   3. Miami
   4. New York

Also, rank order the above cities in closeness to Santiago, Chile.

Think of the answer before scrolling down.

My experience is > 80% misestimate how far east South America is in
relation to North America and miss the answer of New York. 2D Map
<https://www.greatcirclemap.com/roadmap?routes=%20SCL-LAX%2C%20SCL-MIA%2C%20SCL-JFK%2C%20SCL-IAH>

And now it's easy to ask to rank the distances:  Globe View
<https://www.greatcirclemap.com/globe?routes=%20SCL-LAX%2C%20SCL-MIA%2C%20SCL-JFK%2C%20SCL-IAH>

   1. MIA  (folks who travel to South America easily get this right)
   2. IAH
   3. JFK
   4. LAX
