Avoiding invalid transitions in land cover trajectory classification with a compound maximum a posteriori approach.
Classifying remote sensing time-series in land cover trajectories can provide essential information about ecosystems functioning and about the impacts of natural phenomena or human activities over the environment. The existing approaches commonly used for this task can present serious drawbacks, suc...

A spatiotemporal database on the energy, macro and micro-nutrients from the Brazilian agricultural production.
To construct this database, we integrate the nutritional content of 62 crops and 5 livestock categories to estimate the amount of 21 macro and micro-nutrients (including energy) that were produced from agriculture in each Brazilian municipality during the last three decades. Additionally, we allocat...

Comparison of cloud cover detection algorithms on sentinel-2 images of the Amazon tropical forest.
Tropical forests regulate the global water and carbon cycles and also host most of the worlds biodiversity. Despite their importance, they are hard to survey due to their location, extent, and particularly, their cloud coverage. Clouds hinder the spatial and radiometric correction of satellite image...

Multi-source change detection with PALSAR data in the Southern of Pará state in the Brazilian Amazon.
Optical data is broadly used for change detection studies, despite being hindered by atmospheric conditions. Synthetic Aperture Radar (SAR) data can be useful for change detection in areas with frequent cloud coverage as SAR systems are capable of obtaining images almost independently from atmospher...
