中国科学院南海海洋研究所--SA06、07区块地质地球物理补充调查-磁力测量数据ZN89l4（走航式测量-MAPM-93）-19980518-19980528

SA06、07区块地质地球物理补充调查重力测量数据集于1998年5月海上调查获取，主要覆盖区域为南海东南部海域，测线按1:100万要求布置，数据主要包含数据点的经纬度和重力值信息。仪器使用KSS30海洋重力仪，GPS无差分定位精度可达 15~25m，实时差分定位精度为1~3m。

The gravity survey dataset for the supplementary geological and geophysical survey of Blocks SA06 and SA07 was acquired via marine surveys conducted in May 1998. It mainly covers the southeastern waters of the South China Sea, with survey lines laid out per the 1:1,000,000 scale specification. The dataset primarily contains the latitude, longitude and gravity value information of each data point. The KSS30 marine gravimeter was used as the survey instrument; the non-differential GPS positioning accuracy can reach 15–25 m, while the real-time differential GPS positioning accuracy is 1–3 m.
