I'm using the Catastral add-on for Google Earth. This lets you see the registration details for each parcela. It's from the 'Ministerio de Economia y Haciendia' and, I presume shows the up to date official detail of the property. I think I got it from the Gencat web site but it was a good while ago.

Mine shows 'Clase: Urbano' and 'Uso: Residential' while our neighbours are 'Clase: Rustico' and 'Uso: Agrario' which doesn't seem so good for living in.

Anyone know more abour these classifications and what they mean regards living in the campo?

If it is reliable then it's obviously a great tool for anyone looking for property.

Pete.
