If you place the sun high above the surface, the whole point of this layer is lost. It is ment to show which spot on the surface the sun is currently directly above. With just a small change of the suns altitude this spot will change with your viewing angle, and at 36,000 km it will be totally useless. It will look more realistic, but the purpose of the layer is lost.

Edit: I can se that the altitude has been changed in the updated placemark. Too bad, I thougt it was a great feature. Totally useless now.

I tried setting height to 0m. This works until the next update, then it reverts to a defined height.

One idea I had was to draw a connecting line to ground. This also gets reset on update.

I just noticed that you can change the height in the parameter of the call to the php-file: Select Edit and set HEIGHT=0 in the URL.

Thanks a lot for making it controllable this way.

No worries.
I personally prefer it at ground level, but quite a few people had asked for the height to be adjustable. So I thought I would add the functionality.

If you edit the height parameter the it should be ok.
E.g.
Change
http://www.gelp.net\files\sun.php?ISKML=1&HEIGHT=2000000
to
http://www.gelp.net\files\sun.php?ISKML=1&HEIGHT=0

SunPosition Online, from sunposition.net, 100% spot on. Uses Magnetic declination so if you select 'True north' the calculations are ajusted for compasses, you can also select from a 'True north' calculation. To get access to all 48,000 odd locations you will need to sign up, non members get 'limited' access to just over 8,000 locations. Sun's azimuth, altitude, and shadow factor calculated at 15 minute intervals 'Members' for your date or date range, you even get a graph. Members can calculate for their own latitude and longitude locations, save locations to their favourites menu for quick access. The application makes calculations for the magnetic declination for every location. There is no easier or more an accurate way of getting these calculations 'as far as I know or can find' than SunPosition by http://sunposition.net/

Hope this helps
