Abstract:
1. A method for analyzing and estimating horizontal accuracy in georeferenced images, the method comprising: inputting into a computer-based device remotely acquired georeferenced images, photo-identified locations from georeferenced images, and real world survey locations of objects on the surface of the earth in x and y directions; calculating using a computer-based device an offset error between georeferenced image locations and real world survey locations of objects on the surface of the earth in both x and y directions; deriving a root mean square error from the calculated offset error in the x and y directions; deriving a circular error probability from the derived root mean square error in the x and y directions; and computing using a computer-based device the horizontal accuracy between georeferenced image locations and real world survey locations of objects on the surface of the earth by using the root mean square error in the x and y directions and circular error probability for geolocation mapping of object locations on the surface of the earth.
