visParams | FeatureVisualizationParameters|ImageVisualizationParameters, isteğe bağlı | Görselleştirme parametreleri. Görseller ve ImageCollection için geçerli parametreler hakkında bilgi edinmek üzere ee.data.getMapId'ye bakın. Özellikler ve Özellik Koleksiyonları için desteklenen tek anahtar, CSS 3.0 renk dizesi veya "RRGGBB" biçiminde bir onaltılık dize olarak "color" anahtarıdır. eeObject bir harita kimliği olduğunda yoksayılır. |
name | Dize, isteğe bağlı | Katmanın adı. Varsayılan olarak "Layer N" (N Katmanı) olur. |
shown | Boole değeri, isteğe bağlı | Katmanın varsayılan olarak açık olup olmayacağını gösteren bir işaret. |
opacity | Numara, isteğe bağlı | Katmanın opaklığı, 0 ile 1 arasında bir sayı olarak gösterilir. Varsayılan olarak 1 değerine ayarlanır. |
