In this paper, the topographic effects on CSAMT apparent resistivity data in Qin Imperial Mausoleum's archeological exploration are described, with a comparison of different correction methods. The results show that different correction methods would yield remarkably different interpretations. Therefore, topographic correction methods should be chosen and used with sufficient care in data interpretation of rolling topography. If we adopt suitable correction methods to make topographic correction, the topographic effects on CSAMT archeological data can be obviously suppressed, and the data interpretation quality can be improved. It is concluded that topographic correction is very important.
