Hey ! Who're you calling a nerd ?

Objective: URL that shows task area geo-image overlaid with
Turn and Landing points.

Google released its API for mapping. See
http://www.google.com/apis/maps/
With a few lines of clever Javascript (ECMAscript, OK, whatever),
you can overlay your own data on top of the google-provided imagery.
Pizza establishments, homes for sale, suspected mafia safe-houses, etc.

So here's the challenge: With a few clever lines, grab the task
area information and list off John Leibacher's world-wide turnpoint
exchange, then overlay it on the google image, for a printable
area layout. Suitable for programming Charlie's string-computer.
And putting in your cockpit. And amazing your nerd friends
(Hey ! Stop that !).


Many thanks to Dave Nadler for the challenge and particularly to John Cotter
for the solution. I have implemented John's javascript for
all of the 750+ sites in the Turnpoint Exchange. For the US, Canada, and
the UK - where Google has roadmaps - the maps and satellite
views are overlaid, and they do a remarkably good job. Check out Uvalde -
http://soaring.aerobatics.ws/TP/Goog...ooglemaps.html - where
the start, finish, and turnpoint nicely line up on the runway. The info
displayed is the turnpoint name, and the number, ID, and ICAO where
available.

fly safely,

John Leibacher
