GE API Page and Polygon Editor

June 12th, 2008 1 comment

I’ve added a new page (in the menu on the left) to index my GE browser Plug-in projects, with three more examples to go alongside the flight simulator game and bounce! animation.

Delving into the API…

  • A basic Polygon Editor. Something I plan to develop further. Use draggable pushpins to rotate, re-size and locate a single, regular polygon or circle anywhere on the globe, then export the result as a KML file. An info panel populates with values for circumference, area, radius and bearing in real time.

And a couple hooking into some of my pre-existing KML files:

  • Mouseover Flight Route Maps for three European low-cost airlines: Easyjet, Ryanair and Wizzair. The information in these is several months out of date so don’t rely on it being accurate.
  • A view based Hertszprung-Russell Diagram – a scatter plot of stars’ luminosity vs colour – for Sky mode (obviously). Which includes 3000 nearby stars from the Hipparcos catalogue. Built around an unusual KML hack, which I’ll write about another time.
