I've just watched your video. Whether you use, as you did in your example, collimination height, or the alternative rise and fall, it is safer to go from the backsight to each intermediate and foresight, rather than from one to the next, as any error in a calculation going from one to the next will impact all calculations from that point. Going from the back sight to each will only impact the specific calculation where the error was made EXCEPT if it's made at a change point, for those new to taking levels a change point is where you need move the instrument, and the last reading before moving is a foresight, and after resetting up the instrument, you read back to the same point and record it as a backsight. The difference in the readings merely represent the vertical change in horizontal plane of the instrument. The final results will be identical.

Hi Dennis Thanks for the suggestion, I have never seen it done this way but as you say the results should be the same.

Hey thanks a lot Mr Buildsum. its' really very helpful and found it interesting following your video's. I took a course in the year 1981 and cut off from all that goes to surveying. I am a bit lost and want to go upon again. So far i can manage to put myself into the picture and what i want to ask about is whether there exist any software for surveying and levelling.

Kiran Dewoo Hi Kiran, For taking levels, I recommend using a field book, as shown in this video, and either use s calculator or as suggested, use a spreadsheet or similar to do your addition/subtraction to determine your relative levels. Surveying is a different matter. Total stations, which have capacity to measure distances and instantly display horizontal bearing, vertical angle from the asmith (horizontal) actual distance from the instrument to the target being measured, and the horizontal and vertical dimensions to that target. The can record all that information, and depending on instrument can display some of it in graphic form on it's screen. they also can interface to a computer and in some cases directly into programs like Auto cad. That is a big step from taking levels and taking some horizontal measurements using a tape measure or stadia wires if the level has them.

Just wanted to check if you have negative readings (i.e. a negative number is recorded in the table) on intermediate sight, how do you calculate RL for that station?
@Buildsum
@Buildsum 2 жыл бұрын
Hi Angela, inverted readings are recorded as a negitive on the Level book and calculated as a negitive number, so if you minus a negitive number you are effectively adding it on to the HOC. This video may help kzfaq.info/get/bejne/gdWGe5mEyMibh3U.html

Hello sir, can you explain how to find the HI of the IS position ...
@Buildsum
@Buildsum 6 жыл бұрын
Hi Abdul Assuming that HI is Height of Instrument and IS is Intermediate Sight. For a start, the term Height of Collimation is just another term for Height of Instrument so that might help otherwise the HI for the IS is the same as the FS (Foresight) until you get to a change point. With that information and the video, I think I should have covered your question. Hope this helps
