Cuerpos de agua de México fuertemente contaminados (línea de tiempo entre 2002 y 2013)


Visualizar datos espaciales es un reto. Como ejemplo pongo el mapa de los cuerpos de agua fuertemente contaminados. Los datos son de CNA de los años 2002 y 2008 a 2013 de la página de la Comisión Nacional de Agua – Sistema Nacional de Información del Agua (SINA) donde están los datos de la contaminación. Sin embargo, la presentación es muy mal. Por suerte se puede descargar los datos. Pero aún así, me llevó más de un día completo asignar coordenadas a los datos. En otra página de la CNS en relación a indicadores de calidad del agua está la liga para descargar los datos del monitoreo 2013. La tabla en excel tiene las coordenadas de las estaciones. Así, que pude vincular los datos del SINA con esta tabla (aprox. 95%).

El resto fue rápido (media hora). Cartodb tiene una función para presentar datos sobre una línea de tiempo, desafortunadamente, la función está limitada para puntos. El resultado está arriba.
