Hey,
I have csv file of co ordinates (x,y,z) I surveyed, I have to produce progress drawings showing stockpiles, boundary etc. , which I can do easily enough by uploading the co ordinates. I would like to include contour lines in the drawing but I have no idea how to go about it. I have spent a while searching online & I'm even more confused, most discussions refer to TINs and triangulation but not sure how to go about it. I have a survey of the site survey csv file prior to any works carried out & that is what i would like to base my contour lines on. The site is relatively flat, about 4 acres in size, relatively even rectangle shape with fall of 200mm from north to south & fall of 2.5m from east to west.
If possible could someone please tell me how to go about this?
Any help is very much appreciated.
Thanks
