Quality Assessment (Data Quality Attribute Accuracy Report):

Quality Assessment:

Please refer to the Brazilian National Institute of Meteorology (INMET): http://www.inmet.gov.br. Altamira is an agricultural colonization front that opened up in 1971. In this area, we find slash-and-burn cultivation as well as plantation agriculture and mechanized agriculture. Length of fallows vary in these communities.
