Determining a Threshold to Delimit the Amazonian Forests from the Tree Canopy Cover 2000 GFC Data [PDF]
Open global forest cover data can be a critical component for Reducing Emissions from Deforestation and Forest Degradation (REDD+) policies. In this work, we determine the best threshold, compatible with the official Brazilian dataset, for establishing a

BioDinamica: a toolkit for analyses of biodiversity and biogeography on the Dinamica-EGO modelling platform [PDF]
Biogeography and macroecology are at the heart of the debate on ecology and evolution. We have developed the BioDinamica package, a suite of user-friendly graphical programs for analysing spatial patterns of biogeography and macroecology.

THE URBAN HEAT ISLAND OF PORTO ALEGRE, RS, SOUTHERN BRAZIL: AN ANALYSIS BETWEEN 1985 AND 2019 THROUGH THE RADIATIVE TRANSFER IN THE INFRARED THERMAL [PDF]
The objective of this study was to verify the evolution of surface temperature associated with land use and land cover from 1985 to 2019 in Porto Alegre, RS, Brazil. The methodological procedures were performed in five steps: 1.

Modelling dry biomass dynamics in the Cerrado Biome
The volume of dry biomass is a key predictor of fire propagation in the Cerrado biome. Traditionally, biomass dynamics is measured directly onsite through field experiment. However, onsite measurements are constrained by costly logistics needed to cover

Fire propagation model in the cerrado biome
To date, there are no model available for fire propagation in the Cerrado. Especially, for helping fire management and prevention, models need to run under near-real time conditions at a local scale.

CALIBRATING CELLULAR AUTOMATA OF LAND USE/COVER CHANGE MODELS USING A GENETIC ALGORITHM [PDF]
Spatially explicit land use / land cover (LUCC) models aim at simulating the patterns of change on the landscape. In order to simulate landscape structure, the simulation procedures of most computational LUCC models use a cellular automata to replicate ...
