1. A non-transitory computer-readable storage medium comprising instructions embodied thereon which, when executed, cause a computer system to perform 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;
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;
comparing said at least one set of coordinates with said set of georeferenced coordinates;
determining that said at least one set of coordinates more precisely describes the position of said point of interest;
replacing said set of georeferenced coordinates with said at least one set of coordinates to describe the position of said point of interest within said georeferenced image; and
applying said correction to a second set of georeferenced coordinates of said georeferenced image to describe the position of a second point of said georeferenced image.

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.

1. A non-transitory computer-readable storage medium comprising instructions embodied thereon which, when executed, cause a computer system to perform 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; 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; comparing said at least one set of coordinates with said set of georeferenced coordinates; determining that said at least one set of coordinates more precisely describes the position of said point of interest; replacing said set of georeferenced coordinates with said at least one set of coordinates to describe the position of said point of interest within said georeferenced image; and applying said correction to a second set of georeferenced coordinates of said georeferenced image to describe the position of a second point of said georeferenced image. - View Dependent Claims (2, 3, 4, 5)

6. A computer system for implementing accurate digitization from a georeferenced image comprising:
-
a feature locator implemented with hardware of said computer system and configured to receive at least one set of coordinates which have been measured at a point of interest; a registration comparer implemented with hardware of said computer system and configured to determine whether a level of accuracy associated with said at least one set of coordinates is greater than a second level of accuracy associated with a set of georeferenced coordinates which describes the position of said point of interest within a georeferenced image; a correction generator implemented with hardware of said computer system and configured to determine a correction which describes a difference between said at least one set of coordinates and said set of georeferenced coordinates; and a registration updater configured to apply said correction to a second set of georeferenced coordinates of said georeferenced image to describe the position of a second point of interest within said georeferenced image and the registration updater further configured to replace said set of georeferenced coordinates with said at least one set of coordinates to describe the position of said point of interest within said georeferenced image. - View Dependent Claims (7, 8, 9, 10)

11. 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; using said computer system to determine that said at least one set of coordinates more precisely describes the position of said point of interest within said georeferenced image than said set of georeferenced coordinates; using said computer system to replace said set of georeferenced coordinates with said at least one set of coordinates to describe the position of said point of interest within said 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 (12, 13, 14, 15)
