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.
