BRIEF DESCRIPTION:<\/h4>\n\n\n\n

P\u00e9rdida de vegetaci\u00f3n y vegetaci\u00f3n secundaria (formaciones boscosas y no boscosas).<\/strong><\/h6>\n\n\n\n

Para generar estos productos se utiliz\u00f3 de insumo los mapas anuales de cobertura y uso del suelo (LULC) de la Colecci\u00f3n 3.<\/p>\n\n\n\n

Se tom\u00f3 como a\u00f1o de inicio 1999, ya que a\u00f1os antes los mapas presentan inconsistencias temporales debido a la escasez de im\u00e1genes satelitales disponibles que generaron vac\u00edos de informaci\u00f3n.<\/p>\n\n\n\n

A partir del a\u00f1o 1999 se comenz\u00f3 a aplicar el conjunto de reglas del algoritmo para identificar eventos de p\u00e9rdida de vegetaci\u00f3n y vegetaci\u00f3n secundaria, detectados desde el a\u00f1o 2001. Esto se realiz\u00f3 analizando los cambios anuales de cada p\u00edxel en los mapas, considerando tanto los a\u00f1os anteriores como los posteriores a cada a\u00f1o evaluado, seg\u00fan los criterios definidos para el algoritmo.<\/p>\n\n\n\n

Consecutivamente a la aplicaci\u00f3n de las reglas (Tabla 1) se aplic\u00f3 un filtro espacial de 0.5 hect\u00e1reas:<\/p>\n\n\n\n

Based on the trajectory analysis along the time series, the algorithm assigns each pixel to one of the established classes for the product:<\/p>\n\n\n\n
