Landsat has an average resolution of 30 m, so it is common to associate the area of ​​a pixel with 900 m2. But, since the original MapBiomas Paraguay data is created following the representation of the GEE standard (Lat / Long and WGS84), it does not use an equivalent projection (equal area). Therefore, the distance from the target to the equator influences the pixel size. Therefore, on a continental scale, the pixel count calculation and multiplication by 900 m2 should be avoided. In MapBiomas Paraguay the calculation is performed in Google Earth Engine, we apply the function ee.Image.pixelArea () that generates an image in which the value of each pixel is the area of ​​that pixel in square meters, taking into account the possible cartographic distortions.
