可从常用数据只读存储器(CD-ROW)提取有关数据,其中存储了包括整个北美区域大陆和海洋方面有关地球物理学科的广泛内容。地形测量学包括以5′网格表现的隆升和水深测量值;也能提供以30″网格表现的毗邻美国及其沿岸水域的数据集。重力资料包括以6km或2.5′网格表现的自由空间异常和布格异常。也能方便地提供美国本土以4km和2.5′网格表现的均衡异常、自由空间异常和布格重力异常。磁异常资料能提供以2km和2.5′网格的磁异常;同时亦能提供由MAGSTAT地球
Relevant data can be extracted from commonly used data-read-only memories (CD-ROWs), which store a wide range of geophysical disciplines covering the continental and oceans of North America as a whole. Topographic surveys include uplift and depth measurements in a 5 ’grid and can also provide data sets in contiguous 30 "grids adjacent to the USA and its coastal waters. Gravitational data includes a 6 km or 2.5’ grid Free space anomaly, and Bouguer anomaly, but also provide an equilibrium anomaly, free space anomaly and Bouguer gravity anomaly in the United States at 4 km and 2.5 ’grids conveniently. Magnetic anomaly data can provide magnetic anomalies with grids of 2 km and 2.5’ Also available from MAGSTAT Earth
