How to get actual X,Y,Z data points to make As-built plot plans in the field?

3d scanner z image

vijay s

I need to make as-built plot plan of equipments, instruments, pipelines and civil structures in a pretty large industry. I wonder if there is an instrument which can give me X,Y,Z data (with a known reference point 0,0,0) if I can direct a beam (or something) at a particular point (I am thinking of instrument like temperature gun, which when pointed at a surface gives digital reading of temperature). Please let me know if there is something out there which could be useful. Thanks, Vijay

Answer
Sounds like you need a survey carried out using either a total station instrument (electronic theodolite with laser measurement capability) or a laser scanner.

A total station will be able to measure discrete observations on the points of interest and relate them to reference points. All observations will be coordinated (xyz) relative to these reference points.

A laser scanner is a similar type of instrument which observes thousands of points per second and builds up a 3D point cloud with a user defined resolution (as low a 1mm is possible). The data is also related to the reference points. The data is post processed to extract the detail required.

Both methods allow the detail to be located in x,y and z and also drawn up in CAD.

Total station surveys are the cheaper option and the most easily available (any Land Surveyor)

Laser scan surveys are more expensive and not as readily available. Laser scan surveys are more beneficial where the detail to be measured is very complex.

}

WHAT DOES IT MEAN TO SUBSTRACT 1 FROM DAY1.. LIKE WHAT HAPPENS.. can someone please explainnnnnnnn?????

Answer
Enter day:
3
Enter number of days in month
30
Sun Mon Tue Wed Thr Fri Sat
1 2 3 4 5
6 7 8 9 10 11 12
13 14 15 16 17 18 19
20 21 22 23 24 25 26
27 28 29 30BUILD SUCCESSFUL (total time: 5 seconds)


see i entered 3 for days and 30 in month and it prints the following
what happens: if u enter 1 then it by code (day1-1;==1-1 is 0) so nothing happens it prints all numbers in this case 30 i entered in a line with 3 spaces between numbers, but if u entered any other number like it did here 3 so as per code(day1-1; == 3-1 is 2 in a week 7 days so 7-2 is 5 ) so it prints first 5 number from 30 in the line one (1 2 3 4 5) and then it continues the rest to print , note now it leaves 4 spaces before printitng number 1 in first row ...

now i enter 5 in days and 30 in month days see what happen !!


Enter day:
5
Enter number of days in month
30
Sun Mon Tue Wed Thr Fri Sat
1 2 3
4 5 6 7 8 9 10
11 12 13 14 15 16 17
18 19 20 21 22 23 24
25 26 27 28 29 30BUILD SUCCESSFUL (total time: 10 seconds)


now as per code(day1-1; == 5-1 is 4 in a week 7 days so 7-4 is 3 ) so it prints 3 lines in first row leaving four space in front of one and then it continues ....

So SUBSTRACT 1 FROM DAY1 gives a value and then in a week 7 days so 7 take away the value u get gives how many numbers to print on the first row....

hope if its clear....thanks...
