The paper deals with digital correction of EATS MSS Bulk digital data for high resolution image data base. Geometric and geographic correction will be done by using five types of polinomials from one to five degree, for three cases of numbers of control points, that is, 45, 35 and 25 points which are selected on both of ERTS digital data and 1 : 50, 000 national base map. Accuracies for the respective cases, will be compared, for the EARTS-1 frame on Nov. 26, 1972 (ID. No. 112600484) . Accuracy will be less than one pixel RMS in the case of more than three dimensional polinomials.
The program will enable the establishment of ERTS image data base which is consisted of digitally corrected MSS data with the interval of 100 meters for each frame of 1: 50, 000 national base map. The data base is considered as well utilized data base for not only remote sensing scientists but also planners, engineers and governmental officers.
