Attribute Extraction and Landscape Metrics
MÉTRICAS DA PAISAGEM APLICADAS NA EXTRAÇÃO DOS ATRIBUTOS
Métricas Descrição
Class Area (CA)Calcula a área total das manchas de
desmatamento na célula de paisagem.Percent LAND
(%LAND)Calcula a porcentagem da área da célula
desmatada.
Patch Density (PD)Número de manchas de desmatamento dentro
das células de paisagem por km².
Mean Patch Size (MPS)Calcula a o tamanho médio das manchas de
desmatamento.
Landscape Shape Index (LSI)
Calcula a complexidade das manchas de desmatamento dentro das células baseado em
suas áreas e perímetros.
Mean Shape Index (MSI)
Calcula a complexidade média dos padrões de desmatamento dentro das células baseado em
suas áreas e perímetros.
Area Weighted Mean Shape Index (AWMSI)
Calcula a complexidade média das manchas de desmatamento ponderada pela sua própria
área.Mean Patch Fractal Dimension(MPFD)
Calcula a complexidade média das manchas de desmatamento usando logaritmos.
