Dear itrivi, in this changeset you have added https://www.openstreetmap.org/node/11871752648 with a height of 982. The "Cartografía Ráster del IGN" shows this peak with a height of 981, and on the PNOA Spain imagery this peak is not visible at all. So which is your real data source for this peak? Will I find similar discrepancies when I look at the many 100 other peaks you have added recently?
