Potential of Pléiades mono- and tri-stereoscopic images for the agricultural mapping in Mayotte [PDF]

, 2014
In Mayotte, the agricultural land use is only partially known, due to very little GPS plot sampling, while an exhaustive mapping would be needed for decision support.

IMPACTO DA RESOLUÇÃO ESPACIAL EM ABORDAGENS CLASSIFICADORAS POR PIXEL E GEOBIA

Revista Políticas Públicas & Cidades
Este estudo realiza uma avaliação da eficácia dos métodos de classificação por pixel GEOBIA na identificação do uso e cobertura do solo em áreas urbanas. Utilizamos dados provenientes dos satélites Landsat 8, Sentinel-2 e WorldView-2, que foram processados na plataforma Google Earth Engine, aproveitando sua capacidade de processamento em nuvem e acesso
