The First World War left its mark on the ground surface of Europe as perhaps no other human catastrophe before or since. The author applies modern digital mapping technology to the aerial photographs taken by the intrepid early pilots, and creates a landscape of military works that would not have been known in detail to either historians or generals at the(More)
— A lot of disciplines (e.g. archaeology) have to process imprecise temporal information. There are different possibilities to handle this kind of information, amongst them e.g. fuzzy set theory and rough set theory. In this paper, due to its capability in the context of many data acquisition applications, the focus has been set on rough set theory. To(More)
Every event has an extent in time, which is usually described by crisp time intervals. However, under some circumstances , temporal extents of events are imperfect, and therefore cannot be adequately modelled by crisp time intervals. Rough sets and fuzzy sets are two frequently used tools for representing imperfect temporal information. In this paper, we(More)
Rough set and fuzzy set are two frequently used approaches for modelling and reasoning about imperfect time intervals. In this paper, we focus on imperfect time intervals that can be modelled by rough sets and use an innovative graphic model [i.e. the triangular model (TM)] to represent this kind of imperfect time intervals. This work shows that TM is(More)
