Obtain Latitude and Longitude Under Mouse in Google Earth

soundingjet · May 25, 2013

I'd like to obtain the latitude and longitude under the mouse cursor at any given time while operating in Google Earth. I'm struggling to find a solution. Does anyone have ideas?

Currently, the information is displayed in a Qwidget on the bottom right hand corner of the screen. I'd like to be able to retrieve that info with AutoIt.

I've tried using the Window Info tool to find a control that has this info. Also, the RanorexSpy program that has been suggested for manipulating Qwidgets. No success with either.

The COM interface for Google Earth is depreciated and the documentation is non-existent on the web anymore. I'd accept this as a solution, but from what I have found I don't see a function that obtains the current mouse lat/lon.

Any ideas?

Try the window info tool, if that cant pick anything up the only other thing I can think of is to read it from memory.

While the COM may be deprecated, it may still be available, it was earlier eventhough they said it would be removed.

Look through this old code I wrote, especially the "Func Distance()" function.

You cant run the code, alot of files missing, and I cant test it for you as my main rig is down (bad c: drive) so currently on a netbook.

COM still seems to work for me, Thanks for that example.

;~ Google Earth Object
$vGoogleEarth = ObjCreate("GoogleEarth.ApplicationGE")

$vCoords = $vGoogleEarth.GetPointOnTerrainFromScreenCoords(0.66,0)

;~ Latitude and Logitude
$vLatitude = $vCoords.Latitude()
$vLongitude = $vCoords.Longitude()

;~ Print Lat & Long to console
ConsoleWrite("Lat: " & $vLatitude & " Long: " & $vLongitude)

Thanks for the ideas. I've played around with the COM interface. GetPointOnTerrainFromScreenCoords seems to work. The format for the arguments is a relative position from the center of the render window. So the middle of the render window is 0,0. The top left is -1,1...top right is 1,1...bottom left is -1,-1...bottom right is 1,-1.

You have to take into account the window size, client size, mouse position, border widths (top and sides) to get the correct absolution position on the screen. Then convert that to the fractional coordinate format the COM call requires. Perhaps this can be made easier with the Opt's you used would make these calculations easier (I converted everything to absolute screen positions...looks like the Options make this much simpler to handle).

The returns from the COM call are a bit sluggish to make it "real time". But I think this is on the right track.

Thanks for the help.

Be aware that Google throttles certain requests, not sure about lat and lon, I guess those are unlimited, but requesting Altitude is limited to 25000 requests per IP per 24 hours.

When that limit is reached everything begins getting slow, with very limited bandwidth from google, so one has to wait 24 hours for the next 25k batch.
