AI Thread Summary
The discussion centers on the definition of a "changed point" in geomatics, which is described as the location of the staff when the level is moved, emphasizing that it should be stable and well-defined. There is some confusion regarding whether the changed point refers to the location of the staff or the measuring device, with references to its role in carrying measurements forward during surveying tasks. Participants express uncertainty about the terminology and its application, suggesting a need for contextual clarification. The conversation also touches on the potential for confusion with similar terms like "charged point." Overall, the dialogue highlights the importance of precise definitions in surveying terminology.

Homework Statement


According to my notes , changed point is
•Location of the staff when the level is moved. Changed point should be
–Stable,
–Well defined
but , in another online notes , changed point is defined as points of measurement which are used to carry the measurements forward in a run. Each one will be read first as a foresight, the instrument position is changed, and then it will be read as a backsight.

Homework Equations

The Attempt at a Solution


so , what is changed point ? it is the location of staff or location of level ( i am not sure what is level here, but i think it should be the measuring device)

Is this in relation to a particular figure or problem? I think you need to place it in some context.

Something to do with a position transducer?
 
It sounds like it's related to surveying.

No worries, I'll move it to the Engineering schoolwork forum -- EDIT -- Oh wait, it's already there...

LOL, when I first read your post, I thought you were asking about a "charged point", not a "change point". Boy was I confused! o0)
