Geodetic marks
The layer of geodetic marks, created from a recent specific project (ETRS89), can not match with cartography due to the time gap between the origin of both data, but constant update of this cartography has into account this new data.

Summits
The layer of summits, created from a recent specific project, can not match with cartography due to the time gap between the origin of both data, but constant update of this cartography has into account this new information.
These summits have been computed from a near geodetic mark, doing a geometric leveling to determine the highest point (of the summit). This point has to be imperatively a permanent natural point and never an anthropic element (human building) or a pile of rocks handmade. Once measured the geodetic mark with GPS and decimetric accuracy and ellipsoidal height, orthometric height is determined extracting the EGM08D595 geoid ondulation. Later, difference in height between the mark and the summit has been added.
