Various kinds of geodetic data; for examples, levelling, triangular, gravimetric and other data, have recently been stored in relation to researches for earthquake prediction and other purposes. Under these circumstances, to develop a data processing system for efficient utilizations of such geodetic data would be considered one of the most important and urgent problems. On the other hand, a graphic display unit of refreshing-type has recently been showed its capability to the full for handlings of graphically represented data in computer science. Therefore, its application to geodetic data which would be considered suitable for the graphic representation brings many advantages to data processing. A computer program for time-space representation of the geodetic data has been developed by means of a graphic display unit of refreshing-type. The main procedure of the program consists of two steps. One is an interpolation for missing values of the geodetic data in time-space domains, and the other is a graphic display of the interpolated data. The program was applied to gravimetric data obtained around Lake Biwa in order to demonstrate its efficiency. In addition, some problems of this technique are briefly discussed for the future studies.
