MapBiomas Alerta is not a new alert system, but rather an effort to enhance the usability and effectiveness of alerts generated by existing systems. The MapBiomas Alerta initiative provides, on a public and free platform, alerts of native vegetation loss from various detection sources, such as DETER/INPE, SADs, GLAD/GFW, etc. These alerts are verified, validated, and spatially crossed with territorial and governmental data (SICAR/SFB, SIGEF/INCRA, embargoes/IBAMA, UCs/ICMBio, etc.). Details about the validation and publication methodology of the alerts are available at this link: https://alerta.mapbiomas.org/metodo-mapbiomas-alerta/
