Actually, floatingdatum is still horizontal datum, but the datum elevation of different CMP is variable.
实际上浮动基准面还是水平基准面,只是不同CMP的水平基准面高程可以变化。

To cope with these problems, we establish a floatingdatum in the whole area, and perform static correction with refraction static correction.
针对该区的特点,在资料处理中建立了全区统一浮动基准面,应用折射静校正方法解决静校正问题。

The stack velocity calculated on the floatingdatum depends on the velocity of medium underlying the low velocity layer and is independent of topography and low velocity layer.
