Talk:Surveying
From Wikipedia, the free encyclopedia
This page says little about the problems involved with reconciling older, inaccurate surveys and established property lines (fences) with modern measuring techniques. This "art & science" aspect, and the associated legal aspects, are relevant to most property owners, and deserve treatment by someone more knowledgable than myself.
This page needs some work. First to separate the science/profession from the person/professional, then to add a bit more substance to each. Please try to add information without too much reference to local jargon/terminology.--Mikeh 04:01, 2 Feb 2005 (UTC)

[edit] Modern surveying query
I am not a surveyor and so don't really have the knowledge to change this page myself but in the "Modern Surveying" section, shouldn't there be mention of the Automoatic level, which I often see used on building sites. Also, should there be mention of the angle determination capability of the total station?--Commander Keane 09:57, 8 Feb 2005 (UTC)
[edit] Surveyor Comment
The list of types of surveys doesn't mention Construction Stakeout at all, that is the one VERY COMMON ommission from the list. I am not sure what can be done about the local jargon, since surveyors do use different terms in different regions and different nations. Since Construction is linked to this page, IT should have links to Surveying/Surveyor.--Davesjourneys 16:31, 23 April 2005
[edit] 20mm? Surely you jest!
Shouldn't the measure say 2m or 20m? 20mm is 2 centimetres or a bit under an inch. I shouldn't mind this high a degree of accuracy!
- I agree that with one GPS unit, you will be lucky to get 2 m accuracy. However, if you have two recievers the situation can be different. If you place one reviever over a known postion (a bench mark), and then place the other reciever over the unknown postion, you can take the difference between the recordings to get the absolute distance, probably to about the 20 mm accuracy that is quoted. This is because both signals undergo the same (or very similar) distortion through the atmosphere (or very similar at least). Maybe the article needs to clarify this.--Commander Keane 14:55, 2 December 2005 (UTC)
- A single dual frequency survey grade GPS unit, with over four hours occupation time on a point, can routinely get down to the 5mm range if the RINEX files are post processed with the final computed orbits instead of the broadcast orbits. NGS (part of NOAA) offers the post processing for free (a free government service). The NGS site has details (NSG.NOAA.GOV) [The service is OPUS.] Nahaj 03:30, 3 March 2006 (UTC)
[edit] Famous Surveyors
Hmm... Many of them I've not heard of, and can't find by "[name given] surveyor" search in major search engines. I suspect a number of vanity items being inserted. Nahaj 22:33, 27 April 2006 (UTC)
Well there was Lewis and Clark, who were the first surveyors in America...at least that's what my surveying boss said. --Oliver Brody 15:20, 18 August 2006 (UTC)
[edit] Major cleaning required
This article is EXTREMELY US based, and does need major cleaning. I'm going to attempt to universalize this article, and make sure that its not biased towards one legal system. And yes, I do have a expert source that I will get my information from - am Australian consulting surveyor that I work for.
I'm also going to be re-doing the famous surveyors list - I don't think Walt Disney who did "subdivision lot plans" can really be classed as a surveyor. I'll include commented references were possible ----glasnt<3 02:38, 26 June 2006 (UTC)
Dag Nordberg is a famous norwegian surveyor.
[edit] Please merge from Land surveyor
Land surveyor is only one paragraph, overlapping much of this article. I don't feel qualified to judge how much of that article should be added, or how much should replace text in this article. If there is no response here within a few weeks, I will just add the paragraph to this article as a new section and tag it for cleanup. Chris the speller 16:24, 22 February 2007 (UTC)
- I merged the article Land surveyor into a new section here, Land surveyor. Much of it overlaps material that was already in this article, so it should be cleaned up, mostly by trimming. Good luck! Chris the speller 01:45, 13 March 2007 (UTC)
[edit] I'm A Land Surveyor
Ok guys well I am a Land Surveyor and I agree that Land Surveying should be mereged with Surveying as a whole. While Land or Cadastral Surveying is the most prevelent of all types of surveying too much of the material overlaps and the Surveying article is much more complete and accurate. I have made some changes and additions in the article. I agree with previous discussions that the article is very US based, I however have little or no knowledge of modern surveying practices and techniques outside the US. I will attempt to regularly check in and correct any information pertaining to US methods and techniques and I will leave it up to other contributors to expand the article from and international standpoint —The preceding unsigned comment was added by Cbrek04 (talk • contribs) 05:43, 26 February 2007 (UTC).
[edit] Building Surveying
I added a "Building Surveying" section dealing specifically with what building surveying is as when I searched "building surveying" it redirects to the Surveying section but there was previously no information on the subject. However, I noticed that Quantity Surveying and Land Surveying have their own dedicated pages, I'm not sure if Building Surveying should also... (The Beer Baron 22:16, 11 March 2007 (UTC))
- You apparently did not look very hard at the Land Surveying article. It is a redirect back to this article. Chris the speller 23:10, 11 March 2007 (UTC)
- That should have read "Land surveyor" and not "Land Surveying". My mistake. (The Beer Baron 09:03, 12 March 2007 (UTC))
- Then you might have noticed the mergeto and mergefrom tags at the top of the two articles. Land surveyor will probably cease to exist sometime later today. Chris the speller 14:30, 12 March 2007 (UTC)
[edit] Tunnel Surveying
I would like to read a bit about techniques surveying tunnels in this article. For long tunnels the surveyors operates with an accuracy of 1 mm per 100 meters, inside a mountain!
