Aunque no se asocia exclusivamente con embarcaciones pesqueras, es probable que esta capa de actividad muestre embarcaciones asociadas con actividades como la pesca de calamar, que utilizan luces brillantes y pescan de noche.

Esta coincidencia se realiza mediante un modelo probabil\u00edstico que determina los pares de mensajes AIS\/detecci\u00f3n VIIRS en funci\u00f3n de todos los registros AIS disponibles justo antes y despu\u00e9s de la hora en que se tom\u00f3 la imagen VIIRS, as\u00ed como la probabilidad de emparejar un mensaje AIS espec\u00edfico con cualquier de las embarcaciones que aparecen en esa imagen.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">La capa de detecciones de radar, conocida como radar de apertura sint\u00e9tica (SAR), puede detectar embarcaciones en el mar en cualquier condici\u00f3n clim\u00e1tica. SAR puede detectar embarcaciones que no son captadas por otros sistemas cooperativos de seguimiento (ej. AIS o VMS). SAR es un sensor satelital que dispara microondas a la superficie de la Tierra y mide las se\u00f1ales que se reflejan desde los objetos en el suelo y el agua (lo que se conoce como retrodispersi\u00f3n) para proporcionar informaci\u00f3n sobre las caracter\u00edsticas de los objetos.<\/span><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Para ver diferentes tipos de datos de embarcaciones pesqueras,en la parte superior del panel izquierdo, tenemos la secci\u00f3n Actividad.
