TVI (TEMPORAL VISUAL INSPECTION)
Open source online tool for visual inspection of sample points in historical Landsat satellite remote sensing image series.
Created by the Image Processing Laboratory of the Federal University of Goiás (LAPIG - UFG), TVI provides subsidies that facilitate and streamline the process of interpreting satellite series for the training and calibration of image classification algorithms.
In MapBiomas, TVI was mainly used to obtain validation points of the annual pasture area distribution mappings in the Brazilian territory.
