Clarification regarding Prediction timeline

#1

Hi Team,

Needed a little bit of clarification regarding time line of soybean & Sugarcane crops in Brazil.

We have some knowledge that Soy is usually cultivated during Sep-Oct and harvested in Jan-Feb. AS you guys are providing crops in “first crop” time so, when you say a pixel 2020 tif predicted as Soybean, that means that soybean was planted in Sept-Oct 2019 and was harvested in Jan-Feb 2020??

Similarly for Sugarcane, when you say a pixel in 2019 is Sugarcane, that means sugarcane was present on the pixel during Sept-Dec 2018 and was harvested during April-June 2019??

Any clarification or point of contact will be of great help…

Hi! I have the same question.

Hello, @arindamdk8 and @rbzuniga!

MapBiomas maps the growing season of the first crop in Brazil, which means that when a pixel is sugarcane in 2019, it was a sugarcane crop identified around Sept-Dec 2019.

Since collection 7, MapBiomas adopted a dynamic calendar for mapping agriculture classes. It’s based on agriculture crop spectral variation through the year, as a way of identifying the month windows of growing season and off-season in different parts of the country. Check more information on the methodology adopted in Agriculture ATBD Document. (https://brasil.mapbiomas.org/download-dos-atbds-com-metodo-detalhado/
