Method and system for the acquisition of high-accuracy coordinate information without the use of directed electromagnetic radiation
First Claim
1. A method of determining the coordinates of a remote location comprising the steps of determining the location and orientation of an angle measurement device, and then calculating the coordinates of the remote location based on where the shortest path from the angle measurement device intersects the terrain at which the angle measurement device is pointing.

Abstract
A method for providing highly accurate coordinates and elevation of a remote terrestrial-based location is described. The method also provides for the determination of a number of high-accuracy values including the location and elevation of the point of observation, and the distance and bearing from the point of observation to the remote location. Also described is a method for compensating for unknown effects of the associated atmospheric refractivity, and errors in input data.

7. A method of adjusting for errors in mapping aerial imagery to the coordinate grid comprising the steps of:
-
a) obtaining the coordinates of a remote location via a measurement device; b) obtaining the coordinates of a remote location from an aerial imagery map that is substantially the same as the remote location from step a); c) calculating the distance and bearing from the coordinates obtained in step a) to the coordinates obtained in step b); d) using the distance ‘
d’ and
bearing ‘
b’
from step c), calculate new coordinates by starting at the coordinates of the measurement device and moving the distance ‘
d’
away from the coordinates of the measurement device in the direction of bearing ‘
b’
;e) using the new coordinates from step d) as replacement coordinates for the measurement device, obtain a new set of coordinates from the measurement device that represent the coordinates of the remote location adjusted for errors in the mapping of the digital imagery to the coordinate grid. - View Dependent Claims (8)
