Resolution No.24 (1963): Repeat station data for the WMS charts 1965.0

The IUGG recommends that repeat station data from 1950 onwards be supplied to the World Data Centers as a contribution to the WMS, recognizes that earlier repeat station data may be supplied in addition if they are of sufficient accuracy to permit reduction to epoch 1965 with reliability commensurate with the standards set by IAGA for WMS, and considers that survey charts earlier than 1950 may be useful in the historical sequence leading to the WMS charts 1965.0.
