Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Capa vectorial de manglares de Colombia realizada a partir de técnicas de procesamiento digital de imagenes. Para el Caribe y Pacífico la escala de la cartografía es 1:25.000, la metodología se basó en un proceso semiautomatizado en la plataforma Google Earth Engine donde se emplearon imagenes ópticas y de radar para clasificar de manera supervisada el manglar y otras coberturas generales. Se emplearon puntos de campo y de imagenes de alta resolución para entrenar y validar la clasificación. Se utilizaron algoritmos diferentes para Caribe y Pacífico debido a las condiciones particulares de cada zona, para el Pacífico se procesaron imagenes de los años 2019 y 2020, en el caso del Caribe se procesaron imagenes del año 2020. Para los dos casos la unidad mínima cartografiable es de 1600 m2. </SPAN></P><P><SPAN>En cuanto a San Andrés, Providencia y Santa Catalina la escala de la cartografía es de 1:5.000, y su metodología consistió en el procesamiento e interpretación visual de imagenes de alta resolución</SPAN><SPAN /><SPAN>del año 2021.</SPAN></P></DIV></DIV></DIV>
