Activex google earth plugin and matlab

Hello.

I'm trying to open the google earth plugin from matlab, using an activex server because I want to use COM port, so I do this

gE = actxserver('GoogleEarth.ApplicationgE')

But the problem is that I'm not sure if with this command I create a conection with google earth server or with google eart API/plugin server. Being what I really want a conection with google earth api/plugin, how could I do that?

thank you,Javier

• A useful function: http://www.mathworks.com/matlabcentral/fileexchange/20031-google-earth-com-api-example/content/GEserver.m
• The API: http://earth.google.com/comapi/index.html

Thanks Oleg, I'm actually using that references, but I was wondering why I cannot use events and eventlistener related to the COM which I have created as the matlab helps says. Becuase of that I have got the doubt if I have connected to the plug in of google earth.

So what do you get when GE.IsInitialized or GE.IsOnline?

[Javier]

Hi Oleg, sorry for the late reply but I wasn't reported of your reply...

If I execute the function GEserver(ge_in) of the functions you sent me, I got "Startup successful", and google earths opens. So is the plugin running?

thanks

[Oleg Komarov]

Yes it should be running, try one of the example to set the camera on some coordinates.

I can change the camera load,kmls files,and so on, but I cannot use event or eventlisten with this API?

See an example for embedded GE-javascript based API Plugin ( http://code.google.com/intl/de-DE/apis/earth/ ):

Thank you, I'm going to try it, but is a way to get a kye to work locally??

Without having the key I've proved the function ge2ma_demo and I got this error:

??? Error using ==> load

I forgot the fig-file - sorry!!! But now it is also in the zip file, so that it should work!
