How to produce a contour survey

[grain]

Hi

 

I want to produce a 3D model of a plot of land. Any pointers please.

 

I'm guessing I need to borrow a surveyors things and produce a grid of levels and then plot the coordinates and feed it into some software

such as...?

 

What the latest technology for this kind of application?

 

Thanks:wink:

I have moved your question to the "Civil3D & LDD" section.

How detailed do you need it to be? You may be able to find free data online. Here in America we have USGS data available for free.

 

Otherwise it may be better to just hire a surveyor unless you are already experienced. They would use a gps data collector and input points with elevations (levels) then import that data into their software. You could do this with any civil/survey product, however SiteTopo (free) would give you a good start to view and analyze the data as well as give you the ability to export a ground surface for use in another cadd program.

 

Which program you use depends on your budget.

As "surveyors things" can cost from £25,000 upwards, even if you hire it from somewhere, are you going to know which end to point at what? If you have not had a few years training in "surveyors things", I should leave that part to the experts.

i love how people who know nothing of surveying, think any idiot can just pick up some 'things' and be done. i'm glad my father is retired and i went primarily into engineering; surveying just isn't treated as it once was.

forgive me for being a little bitter.
