[edit] Options

Discussion of some of the options

[edit] posList

This is the list of coordinates in the line. The points can be two-dimensional or three-dimensional. The z-coordinate of three-dimensional points will be interpreted based on AltitudeMode.

[edit] Bugs

There are many bugs. The options used in the xml above should work in a relatively predictable manner for drawing lines flat on the surface; experiment with other options at your own risk. The other options are <Extrude>, <OutlineColor>, <MinimumDisplayAltitude>, <MaximumDisplayAltitude>, <DistanceAboveSurface>, <Description>, <Opacity>, and <ImageUri>.
