Chapter 16 — Generating Google Earth Feeds 325
Wrapping Up
Google Earth handles a lot of the application logic that requires JavaScript and programming
in Google Maps. To create similar effects within Google Earth you need only generate the
appropriate KML.This chapter covered the basics of generating markers and points within KML. The basic point
is easy to create. In most cases it requires only the latitude and longitude of the point. Markers
can then be further customized by adding icons and you can even help to improve the visibility
by extruding the icon above the map, making the marker more visible, particularly when the
map is rotated or tilted.You also saw how to refresh KML data. The refresh system allows KML to be automatically
reloaded, and that provides an element of interactivity that enables sequences or time-based
interaction to be overlaid on top of the Google Earth satellite data.
