Hi Jim,
In Google Earth there is a function that allows you to measure headings and
distances. I don't remember what it's called, but it will give you true compass
bearing of the line you draw with it. Check out the tools at the top of the GE
window.
I click on each end of a roof ridge, or the gutter line of a building and then
convert the heading to the standard sundial declination convention for
whichever side of the building that I need.
Hope this helps,
Jim Tallman

Subject: Google Earth Add-on
As I recall, about a year ago someone posted a Google Earth add-on to make it
easy to measure the declination angle of walls or buildings with Google Earth.
I don't even remember what it was called. I would appreciate it if someone
could point me to it.
Thanks,
Jim
