The physical parameter derived from the inversion of electromagnetic surveys, the distribution of subsurface conductivity, is interesting in itself only in very few instances. In most cases, the conductivity distribution will have to be interpreted in terms of the target properties of the survey, for example: a geological interpretation of lithology; a hydrogeological interpretation of hydraulic conductivity; a biohazard/geotechnical interpretation of polluted/not-polluted ground; and/or an archaeological interpretation of manmade/natural finds. The parameters of interest in these categories are often called derived products, indicating that the parameter of interest is not the same as the parameter whose distribution is found in the inversion process of the geophysical data. The interpretation process can be done in a wide variety of ways; from a predominantly cognitive approach based on professional experience, to an application of rigorous quantitative relations found from scientific endeavours.

使用地球物理调查结果推断含水层脆弱性措施

从电磁勘探反演得出的物理参数，即地下电导率的分布，其本身仅在极少数情况下才有意义。在大多数情况下，必须根据勘测的目标属性来解释电导率分布，例如：岩性的地质解释；水力传导率的水文地质解释；对污染/未污染地面的生物危害/岩土技术解释；和/或对人造/自然发现的考古解释。这些类别中的感兴趣参数通常称为导出产品，表明感兴趣的参数与其在地球物理数据反演过程中发现其分布的参数不同。解释过程可以通过多种方式完成；
