"1. What is scale coefficient?In New Zealand, the official datum is New Zealand Geodetic Datum 2000 (NZGD2000), as you can check on DATUM, and the official Projection is New Zealand Transverse Mercator 2000, as you can check on Projection.
"As I am in the middle, I have study both careers and I have stay working as both, I think that I can be more neutral. Usual scopes/responsibilities:
Surveying works: surveys and stake out.
Adjust of design.
"Charlie... of course you are!!! The last thing that anyone should lose: Curiosity.
You are trying in the best you can.
This "silly" (sorry if anyone take it in the wrong way) post is interesting in order to think and to keep in mind that…"
It was the the way it works on the old school instruments (mechanical ones). If you have a Mechanical or electro-mechincal instrument, it was the way it works.
Actually, they are working in a different way. Take a look to this 2…"
Until I know, all the Datum based on MSL, have a value of the orthometric height for their reference. It is not relevance for us, because it is only a translation in height. So you can apply the old MSL or the MSL value plus the…"
"Step by step:
Cartesian ellipsoidal coordinates: You can have a ellipsoidal coordinate through lat and long, but there is no height. It is a mathematic trick for us, but the normal to a ellipsoid is not the normal to an ellipsoid one meter above...…"
"Charlie... more or less you got it.
Regarding the z-factor scale for any ellipsoidal system, there are a pretty amazing formulas that will bring you it. It is useless except for very long distances.
Regarding GPS... The system is not considering…"
"If I don´t undestand it wrongly...
You are in an area when you have a 2º Order Geodetic benchmarks, so do you need to use it and extend it?
You are in an area when you have a 1st Order Geodetic benchmarks and do you need to create a…"
Gravity is normal to the geoid, not ellipsoid.
When you use GPS, usually, you are correllating ellipsoidal height with ortometric height, so you can roughly determine the Geoid waving, that has softer changes than the ones on the…"
Introduction to other Surveyors. One or more sentence Bio about your Relationship with Surveying
I´m strong speciallized in tunnelling surveying. More than 20 years of professional work, and more than 15 years with my father (2nd Surveyor Engineer at Spain). For every work in relation to civil projects, buildings and industrial.

I have experience with the following
GPS, topographic, boundary surveys, construction staking, topographic surveys, control network surveys, ground movement monitoring, teaching, Survey Office, Archeaology, Construction, Expert Testimony, Other
How many years have you been surveying?
Most comfortable with the following types of instrumentation
Total Stations, GPS, Surveying Software, Robotics, Automatic Levels, 3D scanners, GNSS, Other), Old school surveying, theodolite, compass
David , Let me say i think you are a real smart person You have good knowledge and experience , Maybe our regions are the difference . a traverse line is still a traverse but it is not used in this context, this helps separate them.So a traverse is not a traverse line as in a open traverse this is only used in there descriptions .this is to teach new surveyors the difference ,so they will not get confused on what they are working on. because a traverse line has stations this is not used in a traverse.
Land Surveyors United is the world's FIRST Global Social Network for geospatial professionals. We have dedicated, geolocated support groups for practically every country, continent and state on earth, for you to utilize for building your personal network. We are all essentially concerned with the same issues, no matter where we are located on earth. However, surveying practices and methods vary depending on the geographic location where we work. If you have noticed similarities and differences between the conditions, laws and practices between two or more areas of the world,discuss it in this forum.
