COORDINATE SYSTEM UNITED KINGDOM U.K

[Grover_Puma]

Very good to everyone, I am looking for georeferencing and I can't find any suggestions for this area?

I want to know UTM and coordinate system to use

There's quite a few, I've seen OSBG here quite a few times.

Hi Grover,
In addition to Rick's excellent advice, you can find UTM's >>>Here<<<.

very good but how do I get to that picture you show?

[Grover_Puma]

I have seen the page, however I could use wgs 84 as world and then London zone 30 U but for example Spain has

So I would like to know which of these options is for the United Kingdom zone 30 U

[Grover_Puma]

This occurred to me but I'm not sure it's right.

Grover,
Use command MAPCSASSIGN or MAPCSLIBRARY to search for coordinate systems.

I am trying to put in the 3d civil that coordinate system that responds to the project site

Grover,
"Ordnance Datum (Newlyn)"
Civil 3D cares nothing about vertical coordinate systems or geoids.
I don't understand what you're trying to do. What data do you have? What are you trying to design?
Dave

[Grover_Puma]

Civil 3D doesn't care about vertical coordinate systems or geoids.

that´s good data

The only thing I'm trying to discover is the coordinate system that works in the United Kingdom and specifically the image that I show at the beginning of this thread, this to know a little more about coordinate system and how civil 3D works
for example, what happens if I place wgs84 and put zone 30 NORTH

It's the same as putting Ordnance Datum (Newlyn) to Civil 3D, is it the same to put one or the other? or what difference in accuracy is there? etc

Grover,
"coordinate system that works in the United Kingdom"
There are several that you can use to good effect. UTM84-30N covers most of UK. There's no "perfect" coordinate system. Most of the time your choice will be based on what your client wants.
"Ordnance Datum (Newlyn)"
There's really no way to set a vertical datum in Civil 3D.

OSGB 1936 is the one to use
