Adiciona um objeto do EE ao mapa como uma camada.
Retorna a nova camada de mapa.
Uso | Retorna |

Map.addLayer(eeObject, visParams, name, shown, opacity) | ui.Map.Layer |
Argumento | Tipo | Detalhes |

isso: ui.map | ui.Map | A instância ui.Map. |
eeObject | Collection|Feature|Image|MapId | O objeto a ser adicionado ao mapa. |
visParams | FeatureVisualizationParameters|ImageVisualizationParameters, opcional | Os parâmetros de visualização. Para "Images" e "ImageCollection", consulte ee.data.getMapId para ver os parâmetros válidos. Para "Features" e "FeatureCollections", a única chave compatível é "color", como uma string hexadecimal de seis caracteres no formato RRGGBB. |
name | String, opcional | O nome da camada. O padrão é "Camada N". |
shown | Booleano, opcional | Uma flag que indica se a camada precisa estar ativada por padrão. |
opacity | Número, opcional | A opacidade da camada representada como um número entre 0 e 1. O padrão é 1. |
