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-重力测量数据ZH90n10（走航式测量-KSS30）-19980518-19980528

SA06、07区块地质地球物理补充调查磁力测量数据集于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磁力值信息。仪器使用 MAPM-93型海空质子旋进式磁力仪，GPS无差分定位精度可达 15~25m，实时差分定位精度为1~3m。

The magnetic survey dataset for supplementary geological and geophysical investigations in Blocks SA06 and SA07 was acquired during marine surveys carried out in May 1998. It primarily covers the southeastern waters of the South China Sea, with survey lines laid out in accordance with the 1:1,000,000 scale specification. The dataset mainly includes the latitude, longitude and magnetic field values of each survey point. The MAPM-93 marine/airborne proton precession magnetometer was used as the measuring equipment. The GPS positioning accuracy reaches 15–25 m without differential correction, and 1–3 m with real-time differential correction.
