Nieinwazyjna prospekcja średniowiecznego grodziska w Sądowlu. Problem integracji rezultatów teledetekcji archeologicznej oraz historycznych źródeł kartograficznych

The main aim of this paper is to present the potential of an integrated archaeological survey. Currently established survey practice combines a range of methods such as aerial archaeology, airborne laser scanning and geophysics, and analysis of historical maps. It is commonly assumed that the application of more methods will help to obtain more information about the registered archaeological site. However, a cumulation of collected data does not equate with a better understanding of the analyzed structures. Archaeologists often face fragmentary or even contradictory evidence provided by those methods. Integration of data requires a more flexible approach, a thorough questioning of collected data, meaningful comparison of different results, their re-interpretation and the formulation of new questions according to the mechanism of the hermeneutic circle. We illustrate these issues using the case study of an integrated survey at a medieval stronghold in Sądowel. In particular, we focused on various degrees of success with which different non-invasive methods were applied and changing interpretations of recorded structures.
