Improved SCALFUN Analysis of Potential Fields by a Criterion of Ridge–Consistency

摘要

Ridge analysis is well known in the frame of the Continuous Wavelet Transform methods and was recently proposed as a main step of the potential field interpretation method SCALFUN. The information related to more ridges converging to the same one-point source should be consistent, otherwise a poor quality of the estimates of the source properties has to be expected. This can be due to an insufficient resolution of the field and to the non isotropic spatial distribution of disturbances and other source effects. We analyze the ridges converging to the same one point source and use a consistency criterion about the source information retrievable by them. We show that under this criterion the quality of the estimation of depth to source and Structural Index is substantially improved.
