abstract = "Earth observation images are a powerful source of data about
changes in our planet. Given the magnitude of global environmental
changes taking place, it is important that Earth Science
researchers have access to spatiotemporal reasoning tools. One
area of particular interest is land-use change. Using data
obtained from images, researchers would like to express
abstractions such as land abandonment, forest regrowth, and
agricultural intensification. These abstractions are specific
types of land-use trajectories, defined as multi-year paths from
one land cover into another. Given this need, this paper
introduces a spatiotemporal calculus for reasoning about land-use
trajectories. Using Allens interval logic as a basis, we introduce
new predicates that express cases of recurrence, conversion and
evolution in land-use change. The proposed predicates are
sufficient and necessary to express different kinds of land-use
trajectories. Users can build expressions that describe how humans
modify Earths terrestrial surface. In this way, scientists can
better understand the environmental and economic effects of
land-use change.",
