what are the pros and cons of gps in cival engineering?

Answer 1

Almost useless in surveying / engineering as the tolerance is only to the nearest meter.
Can't think of anything within the engineering disciplines I know about that it would benefit, except getting to site.

Answer 2

It has been sometime since I have studied Civil Engineering, (I switched to Mechanical Engineering), but as stated before the disadvantage is simply accuracy. However I remember doing a surveying course in which a plot of land had to be mapped using surveying methods. For those of you who know levelling at all, the levelling required an accuracy of <5mm, and the reference point was approximately 500m away from the site (they didn't make it easy for us!). Anyway, I seem to remember being told that the location and height of the reference point was recorded using GPS, hence (if correct,) it does have its uses. However since everything on the site is measured relative to a fixed point, the exact accuracy of the location of said point becomes irrelevant.

The fact that you still see surveyors using theodolites/levels and reflectors shows that GPS is just not good enough yet, since the price of the equipment is far greater than that of a simple GPS unit.

Answer 3

May I respectfully suggest you learn to spell before attempting an Eng. degree.

I know lots about CIVIL Eng. Nothing about CIVAL Eng. Is that some sort of sport ??????

Answer 4

the cons: possibly a dumb operator

the pros: it may be able to spell "civil"

Answer 5

don't know, but if you need a 3d software contact 3dvision technologies.
