What software are you using?  If you use Civil3D, does it have something to do this?

[kkr028]

sir, we have site data in this type of excel files.

here no surface data and no contour.

only excel like sample file.

The excel has been created by someone so how did they do it, use a sonar device in the Canal ? Yes have seen one used in ponds linked to GPS. Creating cross & Long sections from excel seems a backward step in this day and age.

If so then like Kent use the source data points to make a surface model then extract cross sections. There is free software out there.

Who isn't there? To help me......

I have spent like 40 years as a CIVIL Engineer and accuracy is only as good as your original survey, yes designed roads for like the last 17 years. So would still go down the surface method.

Again how are you making the excel ?

[kkr028]

sir, 

before i go with surface, survey work done in all places or completed land survey before.

but we have only at particular chainage and some levels.

we have excel data it is not used for surface actually .

but it is used for single profile like above picture.
