Google Earth COM API

There's not much about this out there...I guess because it doesn't do much yet. The thing I want to do with it is to be able to make a click on the map in Google Earth have some special behavior. The current API seems primarily focused on letting external applications control the user interface. What I am trying to do is build an enterprise application that will allow sharing of created data- but on an intranet, not to the BBS. Anyway, this is just a summary of what I have dug up. I'll report on my own experiments once they produce something interesting...

The indomnitable TJ gives us the IDL here.

There's an Australian paper (PDF) that references a prototype application they did using the API with VBA in ArcGIS.

I found one (unanswered) post on the BBS:

i use the Google Earth API in vb for a few days
there are the question i can't find the anwser,could you help me?

KHFeature
the KHFeature.visibility can control the places's display
but what the meaning of KHFeature.hasview?

KHInterface
i can run in app as


Dim KH As Object
Dim View As Object
Set KH = CreateObject("Keyhole.KHInterface")
Set View = KH.currentView(0#)


And this guy seems to be doing some things with it. Some good ideas there- at least as starting points.

Still, my goal is to use Google Earth to control other things- and about the only information it is sending out is the bounding box on network links. If anyone has any ideas...send them this way!

Very cool! This will help someone out there. My previous experience working with COM to Java bridge technology has been quite painful, so I hope that this is better!!
