Hi
We are doing a demonstration of Internet facillities at the New Zealand 
Institute of Surveyor's annual national conference at Rotorua in the North 
Island New Zealand.  The purpose of the demo is to convince members in small 
centres to connect to Internet, study the web pages and participate in Forums 
such as these and others which will enhance their continuing professional 
development.  We would be interested to hear from anyone who really values 
these services who may have a message for our conference attendees - we will 
be checking this forum regularly until Tuesday 22nd.
Regards

(Have a look at our test web page at http://www.hn.planet.gen.nz/survey/)

I am looking for an older EDM unit to fit onto my transit.  I don't need
high quality but just a good working unit.
	Thanks Dean   tkc@ncn.net

We have a need for a Sr. Surveying Mgr.  Is there anyone out there
who would be willing to talk to me?

Grant- 
The only problem with getting acquainted with the 'net is that it's so
DAMN ADDICTIVE!
I am a practicing Land Surveyor, having been licensed in 7 states
(currently filling out the application for No. 8) beginning in Alaska
some 22 years ago.
I'm an information junkie, but having seemingly random bits of
knowledge & information has made me a lot of $$$$ and ensured success
and credibility in areas that are related to surveying but seldom
visited by most surveyors.
The newsgroups are probably my biggest source of information, and
contain many "pointers to other places on the net,  (I'll be checking
YOUR website as soon as I send this message!)
Seek out knowledge wherever it may be found - the value of just one
good idea is beyond calculation!!

Pourquoi pas Francais, demandez-vous, mais....
Kysynpä vaan onko täällä näkynyt suomalaista tarinan tynkää
ollenkaan, mitäh ? No toki suomen kieli on melkoinen harvinaisuus 
noin maailman laajuisesti otten mutta asioista voi käydä keskustelua
myös englanniksi, heh !
Greetings from Helsinki, Finland
Tout le monde ne parle pas francais. QUELLE DOMAGE !

Is there a formula that you can apply to change the UTM coordinates from 
one zone to adjacent zone.
For example :
A place somewhere in Canada 
Zone 14 has a coordinate of Northing 5577636.314   Easting 745601.124
This is equivalent (if I am not mistaken) to Zone 15 at coordinate of
Northing 5575059.011   Easting  318315.272.
I know that that the coordinate system was set up to be 0 Northing at the 
Equator (?), and 500,000 at the mid point of the zone.  But how to change 
it  directly ?
Thanks

	The Continuously Operating Reference Station (CORS) GPS network 
managed by the  National Geodetic Survey (NGS), NOAA, is  operating in 
an experimental  mode and will  continue to do so until the  network is
declared fully operational in 1996.  Full CORS integrity monitoring
has not been implemented by NGS at this time.  NGS will do its best to 
ensure the reliability of this service in the interim but, because of 
this status, users of the CORS data should  be aware that NGS cannot 
ensure:
1.  That all current sites will be operational at all times or will be
    kept as part of the final network configuration;
2.  That all GPS data, positional information, utility  software, or
    ancillary information  which has been posted is 100 percent correct
    and without error; and
3.  That any additional  proposed sites that are added in the future 
    will remain  operational or will be kept as part of the network.

NOAA's National Geodetic Survey (NGS) makes available GPS observation data
from the CORS sites with a 30-second sampling rate for most sites. For some 
applications this sampling rate is too slow. Tests have shown that it is 
possible to interpolate observational data at faster rates using Neville's 
algorithm for polynomial interpolation. NGS has created a program (interpo) 
that takes a standard Receiver Independent Exchange (RINEX) format file as 
input and generates another RINEX-format file with interpolated GPS satellite 
observations at a user specified rate. The program is written so that it will 
not interpolate over gaps in the data. The program will interpolate code 
range (pseudorange), Doppler, carrier phase, and receiver clock offsets 
(if available).
The official release version of the GPS interpolation program is now available.
NGS has tested the program and removed all obvious programming errors but we 
could not anticipate all possible applications. Users are encouraged to 
download the software and documentation and try it in their own situations.  If 
you discover problems or have any questions or comments feel free to contact 
Gordon Adams via email at: gordon@ngs.noaa.gov
You may download the docs and program from the NGS FTP site: cors.ngs.noaa.gov
The program and documentation are located in the directory: utilities/Dos. 
The files are:
   - interpo.exe - DOS executable
   - interpo.txt - documentation in ASCII format 
   - interpo.wpd - documentation in WordPerfect 6.0 format

Grant et. al.,
Greetings and best wishes for your conference.  I've been an Internet user for 
about 3 years and have found the I'net to be an invaluable tool for research 
here in the States.  I use it regularly for research, file transfer to client 
offices, and correspondence with clients and sub consultants.  Most of the 
folks I deal with on a regular basis check their e'mail 2 to 4 times a day, so 
I'm never more than 2-3 hours from an answer.  That's important for a one man 
civil engineering / land surveying office like mine.
I hear the Kiwi land development business is booming.....any room for one 
more?  If any of you know a civil engineer by the name of Don Kidd, tell him I 
said hello.
Best regards,
Bill

Maybe someone can see something that I'm missing in this description. It 
is a strip type, about 24000 feet long with 13 curves. The problem is 
that the curve data does not form tangent curves. All of the curves are 
described with a distance and a constant radius of 179.19 feet. The 
consistancy throughout the deed leads me to believe that whatever was 
done was done purposely, causing me to be hesitant to change the deed 
calls. Here is is typical portion of the deed:
". . . thence South 9  30' West, a distance of 353.11 feet to a point; 
thence, by a curve to the left, having a radius of 179.19 feet, a 
distance of 46.98 feet to a point; thence South 5  32' East, a distance 
of 351.60 feet to a point; thence, by a curve to the left, having a 
radius of 179.19 feet, a distance of 89.85 feet to a point; thence South 
34  17' East . . ."
I dug up an old map (the deed is from 1911), and it indicates an 8 degree 
curve on all of them. This seems to be significant because the 179.19 
foot radius is consistant with a 32 degree curve by chord definition. All 
that I can see to do is to force tangency by changing the arc length 
call, if that's what the distance call is, or use broken back curves, 
broken on one end or two? Because this appears to be written purposely I 
hate to change the calls and am leaning toward using curves broken on 
each end.
Any advice?

I am currently an LSIT working in VA and am considering a move to the
"greater" Flagstaff area of Arizona or the Santa Fe-Taos area of New
Mexico.  Of course I am wondering what the market is like in these areas
for a person with my abilities, skills, and background.  I am hoping that
there is someone in "cyberland" from those areas who might be able to give
me some help.  I am interested in salary expectations, job availability,
the general climate of the surveying industry, etc.
I am very appreciative so thank you in advance.

You are probably right in breaking on both ends.  I hope you can find
some corners to prove either way.  
Be cautious on the * arc lengths*.  I have seen some old maps where
the surveyor showed the radius and the CHORD DISTANCE.
This description is insufficient to absolutely prove either way , as
some are,  and you have to use your experience and technical
expertise.
There may not be a *correct* answer but local custom may be shed some
light on how things were done in 1911.
Don't be afraid to go the oldest surveyor (retired or still active)
who may have some experience in your area. Most in our area  are very
willing to help on something like this.
Hope this helps.

I would guess that the 8 degree curve is correct.  My rationale is that a 
7 degree 58 minute curve (pretty close to 8 degrees, wouldn't you say?) 
has a radius (arc definition) of 719.19 feet.  See any similarity between 
that and 179.19?  It looks to me as though someone transposed two digits 
and then followed suit on each successive call.  I'd be tempted to stay 
with the 7 degree 58 minute curve if it seems to work with occupation or 
any other constraints that you may have.  If not, it's time to look for a 
"Plan B" that works.  Good luck.                               Jim

 If the data was derived based on degree of curve, then you can expect
that the distances come from the delta/DOC.  You can usually go through
a test to see if there is a chance of this be examining the radius to
see if it can be made out assuming an even DOC.  You should also not
that not all chord base is based on full 100 foot chords, particularly
as the radius gets small (DOC gets big). It is very likely that the
distances are based son the 100 or 50 foot chords (whatever the chord
base was) and not the arc distance. Stationing is also based 
on chords (not to be confused with the long chord of the curve) not on
arc length is not uncommon.
In the data you provide this quickly proves out.  Your first curve has a
delta of 15d02' assume all curves have a DOC of 32d even, take 15d02/32d
= .4698 so the curve "length" by chord base is 100 times that for 100
foot chord base or 46.98.  Do not confuse this value on a chord base
with any actual distance,  but think about the whole concept of degree
of curve.  On your next curve the delta is 
28d45' which divided by 32 gives a length of 89.8438, so the guy rounded
just a tad.  You also have to remember that these values were probably
taken from tables, and some degree of rounding occured compared to an
exact calculation today. 
The only way to tell if you have a chord base or arc base is what radius
corresponds to a certain degree of curve.  
    In this case by arc base a 32d DOC -> R= 5729.578/32    = 179.0493 
nope
                 a 100 foot chord base -> R= 50/sin(DOC/2)  = 181.3978 
nope
                 a 50 foot chord base ->  R= 25/sin(DOC/4)  = 179.6324 
nope
	         a 25 foot chord base ->  R= 12.5/sin(DOC/8)= 179.1948  **  yep
                 a 10 foot chord base ->  R= 5/sin(DOC/20)  = 179.0726 
nope
So your record was developed by someone who used 25 foot chord base at
that DOC and figured the "length" based on DOC. All curves radial like
good route surveying.  There are books which describe these ranges, but
I don't have one handy.

How perfectly tangent does it need to be?  This is the way I analized it:
The bearings going into and out of the first curve indicate a delta of
15d02', using that in conjunction with the radius of 179.19 feet gives an
arc distance of 47.02 feet, not too bad.
It seems that the difference is in the rounding of the numbers.  For
example if you assume the curve has an absolute radius of 179.19 feet and
an absolute arc length of 46.98 feet you will get a delta of 15d01'18". 
This differs from the delta based upon bearings by 42".  Notice that the
bearings are only to the nearest minute, indicating a precision of +/- 30".
 The 21" per bearing falls within the stated precision of each bearing.
As far as the 8d curve I was without an answer until I read Jerry Wahl's
excellant response on isolating chord bases.
Good luck, I hope this helps.

The two curves described above seem to be mathematically consistent to me, 
within a few hundredths.
e.g. first one; delta = 15d02', r = 179.19: L.C. = 46.97 (arc def.)
     second;    delta = 28d45', r = 179.19: L.C. = 89.91 (arc def.)

I work in a small survey comapnay in Toronto Canada. We have been hooked
up close to a year and the benefits are great. E-mail is perfect for
transfering files and keeping in contact with clients. The Web is an
excellent source for software demos and a place to advertise...although
I think the best way to advertise is through linking with survey-related
Web Pages.
Good luck!

>From what I understand about surveys back in 1911 the centerline was
probably established by running in the streight sections much as we
would today and then establishing the curves using angles from the P.C.
for each of the  100 ft. chords plus one (or sometimes two if stations
are used) short chords to complete the curve.  I would calculate the
layout of the centerline using a method that reflects this.  The
description I would leave as is unless there were some obvious errors. 
Future surveyor's will find that most of our "tangent" curves are broken
back when the measurable precision is ten times as great as it is now.

I am looking for others who participate in bathymetric surveying.  I perform
various surveys in the Chesapeake Bay and the surrounding watersheds.  I am
looking to establish communications amongst other bathymetric surveyors.

Earl-
I'm in Espanola NM, 30 miles north of Santa Fe.
Currently Chief Location Surveyor for the NM Hwy Dept.  Wages are not
real great ($18.90/hr for me).  In charge of six other LS's, five
crews and a research unit.  
My qualifications are registration in 7 states and 32 years experience
- 18 of those running my own firm in Alaska.
Quite a bit of development going on (mostly in other areas of the
state) and good help is always hard to find.  Private wages seem to be
a little better than the State, but sometimes not by much.
Give it another year & you can have my job.  
Keep in touch.

It's been a few years since I've needed one, but my preference at the 
time was for the Crawford scribe.  Lietz used to market one; don't know 
if they still do.  It was okay, though the handle would sometimes pull 
off, and the radius of the arc was a little large for my taste.  
You might check Forestry Suppliers or someone like that.  I know the 
Crawford is available from LO Ink Specialties (800-777-6471).  It's 
expensive ($60), but very well made, and has replaceable blades.
