I'm curious to know what the number count is at each championship.

As in, number of green dots, versus number of red dots. Could you also run this on other cities?

Are you sure you're properly accounting for the possibility of crossing the international dateline?

Crossing the date line shouldn't effect distance...

Crossing the date line:
Sydney to Detroit = 9,478 miles
Sydney to Houston = 8,585 miles

going to the opposite direction (map above)

Sydney to Detroit = about 15,000 miles
Sydney to Houston =about 16,000 miles

No, but it does tend to throw off travel plans (you have to plan for it being a different day on the other side when you get there). That being said, the China and Australia teams (and anybody else in that area) would probably tend to head for the Houston event as being closer than Detroit. (Unless, of course, Detroit was cheaper--if you gotta fly, may as well fly cheap.)

He's taking the "world is still flat" approach.

Bold move, Samuel. Bold move.

Are you saying it isn't? I detect a scent of sarcasm. :-P

Have you ever seen someone fall off the edge of the world?
It isn't a pretty sight...

Just eyeballing this (but I've been a map freak my whole life and a professional oceanographer for half of it), the line separating equidistance from Detroit and Houston passes just about through the teams in China and SE Asia (meaning that it's more a matter of what flights are available), and all of the Australian and Pacific Island teams are closer to Houston.

Also, it would be nice to see a zoom-in so that those two 550 mile circles essentially filled the picture.

First off great job on the ARC GIS mapping of the teams and their location compared to the Championships. Is there anyway to zoom in further to get a better look at the locations?

Great work though.

There is I can get you a .mxd of it if you want but I doubt you can open it.

I think I can export it as a high quality PDF so zooming in would be more useful.

Maybe next unit the world will be round.

I can't suggest Postgres with the GIS tools enough.

Though it is a huge pain a lot of the time, it really is great and it avoids this whole world being flat issue.

I've also used rethinkdb to do some simple geo related queries and am investigating using redis for really basic stuff. (3.0 adds basic geohashing but I'm pretty sure it's actually going to run into the same issue you did here based on how geohashing algorithms divide space)

Can't you publish this to your esri account and share it with other people, then they could download the map and open it on ESRI website.
