                         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.",
