First Claim
Patent Images
1. A method of implementing accurate digitization from a georeferenced image, said method comprising:
- receiving at least one set of coordinates which have been measured at a point of interest; and
determining a correction which describes a difference between said at least one set of coordinates and a set of georeferenced coordinates from a georeferenced image of said point of interest which describes the position of said point of interest.

Abstract
A method of implementing accurate digitization from a georeferenced image is described. In one embodiment, at least one set of coordinates which have been measured at a point of interest is received. A correction is then determined which describes a difference between the at least one set of coordinates and a set of georeferenced coordinates from a georeferenced image of the point of interest which describes the position of the point of interest.

8. A system for implementing accurate digitization from a georeferenced image comprising:
-
a feature locator configured to receive at least one set of coordinates which have been measured at a point of interest; an registration comparer configured to determine whether a level of accuracy associated said at least one set of coordinates is greater than a second level of accuracy associated a set of georeferenced coordinates which describe the position of said point of interest within a georeferenced image, and a correction generator configured to determine a correction which describes a difference between said at least one set of coordinates and said set of georeferenced coordinates. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer implemented method comprising:
-
using a computer system to receive at least one set of coordinates which have been measured at a point of interest; using said computer system to determine a correction which describes a difference between said at least one set of coordinates and a set of georeferenced coordinates which describe the position of said point of interest within a georeferenced image; and using said computer system to apply said correction to a second set of coordinates of said georeferenced image to describe the position of a second point of said georeferenced image. - View Dependent Claims (16, 17, 18, 19, 20)
