The mark of a small dot is used to indicate the height of a spot above sea level. Spot heights are points that have been measured to be exactly that height, in meters, above sea level.
The mark used to indicate the height of a spot above sea level is called a "datum point" or "elevation marker." It provides the reference point for measuring altitude.
To measure human height with a tape measure, have the person stand upright against a wall with their heels touching the wall. Place the tape measure flat against the wall, making sure it is level, and mark the height at the top of the person's head. Then, measure the distance from the floor to the mark to determine their height.
The mark placed under a letter is called an underscore. It is often used in writing and typography for emphasis or to indicate spaces in URLs or file names.
Tides are measured from a datum called the Mean Sea Level
indicated with different kind of contour numbers , which are showed in brown curved lines
Allowing the liquid level to fall below the calibration mark can introduce errors in volume measurement. Inaccuracies in volume delivery can occur due to changes in surface tension or meniscus formation. To ensure accurate measurements, it is important to keep the liquid level above the calibration mark when using a graduated pipette.

They use the same measurement, but height is considered to be above the 'zero mark', while depth is below this mark. Often, the ground, floor, or sea level serves as this 'zero mark'.

The mark above a short vowel is called a breve. It is used to indicate that the vowel is pronounced as a short sound.
You would use a caret (^) inserted above or below the error to indicate it needs to be corrected.
That would be a ditto mark.
The mark used above vowels in some foreign languages is called a diacritic or accent mark. It can indicate things like tone, stress, or pronunciation changes in the vowel.
A red mark above the nose could indicate sensitive skin. Try to use cooler water and keep the area hydrated.
The Thorndike-Barnhart pronunciation key uses a breve mark (˘) above the vowel to indicate a short vowel sound.
Contour lines are spaced at a regular height above sea level - every 50 metres, for example. The highest point of a hill may be just above the highest contour line. Therefore a spot or summit height symbol may be used to mark the highest point on the map.
You first have to have a reference point, beacon or bench mark - this has a known elelvation, or reduced level in metres above mean sea level (AMSL). (Where MSL = 0). When your helper places the staff (graduated measuring staff like a big ruler) on the reference point, read off the value as observed by you, through the machine you are using (level, theodolite, other electronic instruments) and add this to the level of the reference point. This is called the Collimation height and is basically, the height of your instrument, above the reference point (and in turn, above mean sea level). If you helper then holds the staff on another point of unknown reduced level, you takes the reading of the staff through your instrument, and subtract that from your Collimation height. This will then give you the REDUCED LEVEL of the point. Thus, the REDUCED LEVEL IS A LEVEL, ABOVE MEAN SEA LEVEL, OF A POINT AS COMPARED AGAINST A REFERENCE POINT OF KNOWN REDUCED LEVEL. Different places will derive their own AMSL system based upon, obviously, their own local, average sea level.
