NDVI

NDVI (Normalized Difference Vegetation Index) ou Índice de Diferença de vegetação normalizada é utilizado para analisar a saúde da cultura agrícola. Após o processamento da imagem de satélite, regiões com pixels com valores altos de NDVI significam alto vigor vegetativo (valores próximos a 1.0). Regiões com pixels com valores baixos significam problemas de produção agrícola (valores próximos a 0.0).

Regiões com pixels com valores baixos significam problemas de produção agrícola (valores próximos a 0.0). A fórmula é simples, NDVI = (NIR – RED) / (NIR+RED). No caso das imagens fornecidas, NDVI = (B4 – B3) / (B4 + B3).

  • Entrada: Imagem analítica no formato GeoTiff.
  • Saída: Imagem GeoTiff NDVI processada.

$ python ndvi.py
