Talk:Hydrographic survey

Alternative meaning?

A hydrographic survey is also a legal term to describe a water right in the western US. http://www.ose.state.nm.us/legal_ose_hydro_survey.html

The first stage of the adjudication process is the completion of the hydrographic survey. During this process, Hydrographic Survey Bureau and the Litigation and Adjudication Program staff gather all of the information used to legally describe a water right and record it in the report and associated maps filed with the court. The survey filed by the bureau is presumed by the court to be correct. Any party wishing to dispute these facts bears the burden of proving the survey wrong.

The bureau makes every effort to ensure its information is correct. Staff search county ownership records, State Engineer water rights records, historical records, field surveys, field interviews, historical aerial photography and current aerial photography.

All new hydrographic surveys are based on geographic information systems (GIS) technology and all field measurements are now done with global positioning systems (GPS) receivers.

Strategy needed

The article is now very weak in history, international scope and technically. This is also potentially a very large subject expanding well beyond the obvious oceanic hydrographic survey for nautical charting. A strategy for development might help avoid a runaway page. Should it be an introduction defining what the term means, brief mention of the wide international scope of the thing and sub pages dealing with the international aspects? I just added a bit about RN/UKHO and clarified the U.S. section where only NOAA was mentioned and then not its NOS uniformed corps that actually conducts hydrographic surveys. A whole section could develop about the specialized ships and techniques alone. We have to take note too of the odd little "western waters" subject already noted that would only be recognized by a few specialists and residents of the states using such a term. The term "hydrography" covers lakes, streams, rivers and oceans so linked branches need to be considered rather than trying to cover everything in one piece.-Palmeira (talk) 16:22, 24 November 2009 (UTC)

Only a very small percentage of the Hydrographic surveys performed worldwide are for the purpose of nautical charting. To limit this article to nautical charting would omit the bulk of the surveys performed worldwide. Talk to any Hydrographic Survey supply company like HYPACK, Geo Accoustics, Reson, Odom ect. Ask them what percentge of their products is actually used for nautical charting. It is very, very small. —Preceding unsigned comment added by Tugboat069 (talk • contribs) 20:25, 30 November 2009 (UTC)

We can discuss this, but your reversion of my update goes way too far. I added internationally recognized authorities. You seem to be focused on companies. I added sample national organizations dealing in marine hydrography. My point is that "hydrography" is a very broad term ranging from little mom and pop outfits doing local work mapping lakes and streams to major national organizations. I don't want to get into a reversion war, but that revert was unacceptable and I will kick it "upstairs" if necessary. Palmeira (talk) 00:22, 1 December 2009 (UTC)

The bulk of Hydrographic surveys are conducted by companies not governments.

This is the second time you have reverted and eliminated documented, cited references regarding national hydrographic efforts in maritime areas. Regardless of your personal bias that is the origin of nautical hydrography and a major component of present day maritime hydrography. I suggest you add your corporate views to flesh out the article and stop destroying input by others. I am reverting to give you that opportunity. Palmeira (talk) 20:24, 8 December 2009 (UTC)

I have just completed subject headings that should allow for you to expand on your area of interest--and remember the neutral view. Yes, there is plenty of commercial hydrography. Worldwide, and in the U.S. vast sums are expended and assets applied to national, state and local hydrographic survey of public waters. Even many of the private firms working in the field get many of their contracts through such efforts. Any shoving that under a table is simply ignoring fact. I will state, for the last time, that if you simply again undo what I have contributed with cites I will take this to a third party intervention.Palmeira (talk) 22:38, 8 December 2009 (UTC)

Note that in the UK the UKHO no longer carries out any hydrographic surveys. Government sponsored surveys are managed by the Maritime and Coastguard Agency and Nature England, but they are all carried out by subcontracts to commercial organisations. — Preceding unsigned comment added by Smartcom (talk • contribs) 13:56, 26 November 2011 (UTC)

Modern surveying

What era does this cover? · · · Peter Southwood ^(talk): 15:34, 13 January 2023 (UTC)

Suggested split out of Wire-drag surveying

Fgnievinski, you tagged for a split but do not seem to have started a discussion anywhere explaining why. It is not obvious that the section is already large enough to be a stand-alone, not is the full scope of the topic likely to be familiar to most editors. Your credibility and the level of attention likely to be attracted by the tag would be improved by an explanation of why the section should be split out, and possibly by a list of useful references. Alternatively, you could start the article yourself. Cheers, · · · Peter Southwood ^(talk): 15:44, 13 January 2023 (UTC)

It's the only section in Hydrographic_survey#Methods without a separate main article. fgnievinski (talk) 19:45, 13 January 2023 (UTC)
