We have performed mapping of magnetic anomalies on the Moon, Mars, Mercury and Earth, using the magnetic field observation by the spacecraft and the marine magnetic survey. Magnetic anomalies are usually mapped at an altitude averaged for observations. When the Surface Vector Mapping method (SVM method) is applied, three components of crustal magnetic anomalies can be described on the spherical surface of planets. Combined with the appropriate selection of observational data and the iterative process, the SVM method was slightly modified (the iterative SVM method) and applied to the magnetic field observations by the spacecraft around the Moon (Kaguya and Lunar Prospector), Mars (MAVEN) and Mercury (MESSENGER) in this study. For the Earth, a new method of total force anomalies (i.e. ΔF) was developed on the basis of the SVM method: the Surface Mapping with ΔF (SM-ΔF method). Applying the SM-ΔF method, we have estimated the normal component distribution of magnetic anomalies for the slab of 8-24 km depth off the Pacific coast of Northeast Japan. The results by the iterative SVM and SM-ΔF methods enable us to check correlations between magnetic anomalies and other features such as the topography, indicating usefulness of the methods in the magnetic anomaly analysis.
