Abstract | This paper presents a technique for spatial sampling and error reporting for image base maps. The technique is based on the coverage of an image map base, the initial estimated accuracy, and the principle of error propagation to determine a number of check points. The location of these check points is randomly generated to obtain a non-biased evaluation of the overall image map base. A spatial error modeling formula is introduced to estimate the size of error at various locations over the image map base. Data from a recent orthoimage accuracy assessment project is used to show the procedure. The implementation of this technique has resulted in an improvement in the checking procedure of image map base accuracy assessment. |
