Micromagnetic investigations of medieval settlement structures at Kalo castle (Denmark)

Results of micromagnetic investigations at Kal phi peninsula are presented and discussed. We developed a technique to calculate the optimum sensor configuration based on a given grid spacing. This configuration guarantees a maximum spatial resolution while minimizing the influence of near-surface noise and discretization effects. It is demonstrated how to incorporate a priori information based on the operators assessment of the state of knowledge. Surface findings and excavation results were classified as hard boundary conditions for the interpretation. All remote sensing data and interpretation results of prior investigations were regarded as still having a higher degree of uncertainty. Apart from the application of standard filtering and image processing techniques to magnetic data, other processing procedures such as inverse modeling were applied. An image of the urban plan of the area under study is finally presented. (C) 1999 Elsevier Science B.V. All rights reserved.
