abstract = "This work presents a spatiotemporal interval logic formalism and
shows how to use it for reasoning about land use change using big
Earth observation data. Extending the ideas from Allens interval
temporal logic, we introduce predicates holds(o, p, t) and
occur(o, p, Te) to build a general framework to reason about
events. Events can be defined as complete entities on their
respective time intervals and their lifetime is limited while
objects persist in time, with a defined begin and end. Since
events are intrinsically related to the objects they modify, a
geospatial event formalism should specify not only what happens,
but also which objects are affected by such changes. The main
contribution of this work is a spatiotemporal interval logic that
includes geospatial objects explicitly. The formalism proposed and
predicates extended from Allens ideas can model and capture
changes using big Earth observation data, and also allows
reasoning about land use trajectories in regional or global areas.
Spatiotemporal interval logic describe data types and their
operations in a formalism improves our ability to extract
information from large remote sensing data sets. In an experiment
performed in an tropical forest area, our proposed spatiotemporal
interval logic framework was able to discover some events related
the land use change caused by soybeans in Amazonia.",
