Would it be true to say that daldra is 'height from top to bottom [of a person, object etc.]' while uchter (have I remembered that correctly?) is 'altitude, i.e. distance [of an object, person etc.] from the ground'? If not, what is the difference between the two words?
That's right. A dictionary will give you:
- uchder - height, altitude
- taldra - height, tallness, stature
