Named annotations in *meta_[clihf].dat files

Nadie ha tomado este issue todavía.

Hi ladies and gentlemen,

I was wondering how the *.dat files were generated, and if it would be possible to annotate some of them with their names in some standardized format. For instance, for countries, we could append another field after the #bytes value that contains the ISO2 name of the country of the coordinates listed. Then one could build LineCollections for each country and do fun per-country graphing.

Otherwise, we need to use shapefiles -- not all that bad except they might not match the specified resolution or even the data included in basemap.

I'd love to submit patches, but unfortunately there's no rhyme or reason to the internal organization of the *.dat files. I hypothesize having their source will facilitate such a transformation.

Thoughts?

Comienza rastreando cómo se generan los archivos meta_[clihf].dat y entendiendo su organización interna; después, revisa el campo estandarizado propuesto después del valor #bytes. Considera los casos de uso de country ISO2 y LineCollection junto con el enfoque existente de shapefile. Se considera completado cuando el proyecto tiene un formato decidido y documentado, y un origen o ruta de transformación claros.
