What you want is the files for "Líneas Límite Municipales" from here: http://centrodedescargas.cnig.es/CentroDescargas/equipamiento.do?method=mostrarEquipamiento Be aware that Spain doesn't have one "true" set of boundaries. Some municipalities have different data than the regional goverment, which might have different data than the national government. Usually the difference is no bigger than a few meters in the worst case. Submeter accuracy for boundaries doesn't seem like a big problem, until you're faced with the problem of taxing buildings & constructions which lay exactly on a boundary (e.g. http://www.openstreetmap.org/#map=19/40.78820/-4.00284 - I know, first-hand, that there was a small dispute between regional governments about who should tax one of the water depots there) If you want to be extra accurate, you'll have to survey the boundary milestones along the border, recalculate river centerlines and try to match everything to old documents. Speaking of disputes and old documents, what's your point of view about Olivenza? I suggest you get up-to-date on how to tag territorial disputes in OSM. > As a closing note, I'm writing this in English because I'm afraid I'd do a > lot of grammatical errors and be misunderstood if I wrote in Spanish.
