Filtered Geosat altimetry as a tool for global bathymetric chart development



Now that the Geosat altimetry and precise orbit information collected during the 1985–1986 Geodetic mission is declassified, the Naval Oceanographic Office is releasing its chart of Geosat altimetry of the world's oceans (Figure 1). This data set has been used at the Naval Oceanographic Office since 1987.
