Cosmicrocker is correct. The definitions are not tied to absolute elevation but to the average elevation of the surrounding area. But Meridiani is relatively high in elevation. It would be a planum either way.

Phil,
The highest point is the Olympus Mons : 22 km above of what??? and the lowest point is the bottom of crater Argyre is 8 km below of what??? I would like to know what is the height reference for Mars as the ones of Earth with sea level reference.
From what reference, the flat land is refered as Planum and also as Plantia....I know that the southern of Mars has the high level land and the northern of Mars is of low level land.
