Category talk:Zero-level elevation points

Scope
dear : zero-level elevation point is undefined; we have zero-elevation surface, which is a synonym of vertical datum. Therefore, it's not a point; rather, it's a surface, more specifically a coordinate surface. I'd like to suggest merging the present category into its sole parent category, as there's no distinction from vertical datum. fgnievinski (talk) 03:42, 21 June 2024 (UTC)
