Acurácia de mapa e matriz de confusão com o plugin AcATaMa no QGIS

The assessment of map accuracy aims to compare a classified map with reference data to determine how well the map reflects reality, considering a sample. In the video, I explain how to generate map accuracy using a confusion matrix with the AcATaMa plugin in QGIS, a land use and land cover raster from Mapbiomas, and a Google satellite image. The final result is a confusion matrix with overall accuracy, user precision, producer precision, and other spreadsheets. The video also explains some concepts and how to interpret the matrix.
