A quick search did not find any encouragement, and I don't know if GE has the capability.

Does anybody know how to create a polygon (such as a deed plot) with distances and azimuths and only one specified set of coordinates, and then drag it around to different coordinates on Google Earth to see where it lines up best with the image?

All I've found so far is a path or polygon specified by lat-lon coordinates of all the angle points.

My immediate application would be to see if I can figure out where an ancestor lived, on an odd-shaped parcel, in a county a long way from me that has no on-line parcel map.

Hi,

I tried it as well but with no success!
what I suggest is to 'work backward', means, take the picture from Google earth, Geo-Reference it in your cad soft, and then you have more flexibility with your polygon.
unless you are working in small scale, then the picture will be in poor quality!

try this:
using a paper drawing, scan the drawing

from the tool bar select "add"
"image overlay"
browse to image and click on it.
adjust transparency...!!
rotate and scale to fit
very crude but it works.

one example:

PS: for a more accurate scale...
using the measure tool in GE I draw a couple lines at distances as shown on the map image, save, and then scale to that.
A good recon tool

I figured out that some picture formats support a transparent color for your background and others don't.

PNG, for instance, works much better than ordinary GIF and JPG, because PNG supports the transparency and you don't have to compromise between the image background covering up the terrain versus the tract outline being too dim.
