Indigenous Area
Greenline does not allow the use of land areas that overlap any indigenous lands, therefore through the FUNAI Monitoring Portal, it is demonstrated and proven here that the land areas do not overlap indigenous lands.

Deforestation Monitoring
Greenline monitors imminent deforestation risks and also the occurrence of deforestation if it occurs. We use a GIS platform
(Image Geoprocessing) where we slice the area into 50m x 50m quadrants for safer monitoring. Any change within just 1 quadrant will be identified immediately.

NDVI
Normalized Difference Vegetation Index (NDVI) measures the health (greenness) and density of vegetation captured in a satellite image .
Healthy vegetation has a very characteristic spectral reflectance curve, which we can benefit from by calculating the difference between two bands – visible red and near infrared.
CGI
The chlorophyll index is used to calculate the total chlorophyll content of leaves. CIgreen and CIred-edge values are sensitive to small variations in chlorophyll content and are consistent across most species.
EVI
O Enhanced Vegetation Index (EVI) é um índice avançado de vegetação criado com maior sensibilidade à biomassa, fundo atmosférico e condição do solo. É considerado a versão modificada do Índice de Vegetação por Diferença Normalizada (NDVI) com alta potencialidade de monitoramento da vegetação, corrigindo todos os ruídos externos. Os índices de vegetação são calculados a partir da refletância bilateral da superfície que foi ocultada para nuvens, fumaça, aerossóis, água, sombras de nuvens, etc.
