Re: Surveying in the UK

Thanks for the info guys. I have had a look around on the net and now
have the background info on what the different datum's in use in the
UK OSUK39 seams to be the most common. But I was able to find very
little information on how this is ground marked and where one finds
the coordinate values of these ground marks.

Take for example the case of a simple topo survey the first think I
curently do is go to the local lands and survey office, search their
records and find several coordinated ground marked positions in
convenient locations. These then form the basis of my survey control.
The whole survey is then in terms of Geodetic Datum 1949 and it is
then possible to overlay boundary information or aerial mapping for
lands and survey.

I would expect with the amount of construction work going on in the UK
that a simlar procedure would apply but searching google and the OS
website for information on the OSGB39 datum resulted in only
conversions to GPS datums or background information.

Your help is appreciated.
