Great to here that. Thank you for watching.

Thank you watching and for your comments. I will consider it for new uploads.

Thank you for consideration..

Robert thank you for watching. Correct the benchmark is an established point to which all need to reference.

Hello Eric, Thank you for watching. I appreciate it. I am not sure if I understand your question correctly. Let me try. You want to know the elevation of points before the BM? If this is the case, then you would follow the same steps and process for any other point based on that same BM. Please let me know if that works or if I totally missed on what you were actually asking.

@@SkillRender Hello. Simply I have known B.M at a point somewhere on the top of land surface of working space, but I don't know its elevation .

Who stablished the bench mark and how can it take?

The bench marks are determined by the governments. Bench marks are the oficial reference points. Let me know if that helps. Thanks for watching my videos.

Thank you for watching. It basically means to find the station reading at the highest elevation of the curve.

@@SkillRender Should I put 'Therefore, the highest elevation is ...' ?

It would, "the highest elevation .... is at station ...."

OMG thank you😍@@SkillRender
