Re: HOW TO ADD SPEED DATA TO KML FILE

[barryhunter [KML Guru]]

What do you mean by 'speed data tag'?

Perhaps a better question is what are you trying to do? What is this
this tag going to archive?

I still unsure what you mean, where do you wish to display the Speed?

Are you asking how to store it as an value with the placemakr, and
then display it in the description ballon?

Hi Oracle,

While there is no KML element for speed, there are three ways - that I
can think of - to represent speed in KML.

1) You can note the speed in the description balloon:
<description>speed = 200mph</description>
An alternative to this is to use <Data> elements and embed them in the
<description> or <BalloonStyle><text> element, like this:
<Placemark>
<description>speed = $[speed]</description>
<ExtendedData>
<Data name="speed">
<value>200</value>
</Data>
...
for more information:

2) You can change size of a Placemark or the width of the LineString
based on how fast it is.

3) You can change the color of the Placemark or the LineString based
on the speed.

That depends on how your output your KML, but yes that should work. If
you output your speed column in ExtendedData as I posted yesterday.
