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.
Claims20
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.
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.
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.
