Dem map value

[MohamadJouni]

when I  insert my dem map it shows me a value from"155-969" but actually when I use "ID" I have some value bigger or smaller than "155-969"

show picture below

Note I fix the problem by making export for the map then insert but why did that happens first

You have "stretch" applied.

Set it to None and you will see why.

Does the use of Calculate Statistics bring about any improvement?
