Hi,
Spanish cartography is well known for being imprecise, especially this Alpina series.
A few years ago, I remember having an old etrex summit (the one with grey screen with no cartography) in which I entered coordinates of a few waypoints for a trek in Spanish Pyrenees. On the way, my position was the most often false with errors from 30 to 100 m !
Here’s another evidence : on the Basecamp picture below, I drew a route in Topo Alpina Espana (Andalousie)(in purple) that I displayed in Topo Spain v4 in which the corresponding road is yellow. You can see positionning errors up to 100 m !
