In order to identify the lone tree and
its surroundings it may be necessary to view the photos in
stereo
or under magnification. |
 |
Using software such as Delorme's x-map
to do a simple geo-reference in order to extract the rough coordinates
in order to help locate the point in the field. |
|
Other software can be used as well to
get further accuracy or aid in locating the point for extracting
the the rough coordinates in order to help locate the point
in the field. |
 |
Loading the extracted rough coordinates
into a hand held GPS receiver to locate the point in the field.

 |
Once arriving at the destination, confirm
by looking at the aerial imagery in stereo to confirm that you
are in the correct area. You may have to look
around a little as the GPS coordinates will only take
you to the general area. Once the tree is identified
you are able to make your precision survey measurements. (Not
with the hand held unit.) |
