However, since the original MapBiomas Argentina data are 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 line influences the size of the pixel. Therefore, on a continental scale, the calculation of pixel count and multiplication by 900 m2 should be avoided.<br>In MapBiomas Argentina, the calculation is performed in Google Earth Engine, applying the<strong> ee.Image.pixelArea ()<\/strong> function, which generates an image in which the value of each pixel is the area of that pixel in square meters, taking into account possible cartographic distortions.<\/p>","protected":false},"template":"","faq_categoria":[],"class_list":["post-380","faq","type-faq","status-publish","hentry"],"acf":[],"uagb_featured_image_src":[],"uagb_author_info":{"display_name":"Adriel Fernandes","author_link":"https:\/\/argentina.mapbiomas.org\/en\/author\/"},"uagb_comment_info":0,"uagb_excerpt":"Landsat tiene una resoluci\u00f3n promedio de 30 m, por lo que es com\u00fan asociar el \u00e1rea de un p\u00edxel a 900 m2.
