%X The monitoring of land use and cover changes is essential for un- derstanding several environmental and socio-economic processes in the World. This monitoring requires novel software tools able to process big spatiotempo- ral data sets generated from Earth observation satellites efficiently. To generate land use and cover maps, researchers from different areas need high-level mech- anisms to easily handle these big data sets. Thus, this paper presents a query language for spatiotemporal data based on an algebraic formalism. By defining and implementing a temporal interval algebra, we can answer questions about land use and cover changes. For each location in study area, a time series is extracted of pre-processed and classified Earth observation data.
