Accurate digitization of a georeferenced image

摘要

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.
