Copy these files to: C:\Program Files\Corpscon6\Vertcon
Now for me, this is where it gets interesting, because even though you have
selected the customized grid file, it will not use this customized file in
the calculations, even though it say its using it in the header of the output
file!
Here's where I exit the program and then start it up again...try it.
One way to insure that the correct model is being used, would be to visit the
NGS website (they only run the old model), and run a point through their
online version of the VertCon program thereby getting a second opinion:
http://www.ngs.noaa.gov/TOOLS/Vertcon/vertcon.html Click "Height Conversion"
on the left side. If you run a coordinate here, say 27 00 00.00 and 081 12
00.00, you will get a datum difference of -0.353 meters (-1.158 ft). Then
run this same position through CorpsCon, and see if you get this number or a
different conversion. I know this is not to most comforting nor scientific
system, but the other option is to wait until the next version of Corpscon is
released...December 21, 2012.
If you want to never have to think about this again, you could go to
C:\Program Files\Corpscon6\Vertcon on your hard drive, and rename the file
vertcone.94 to vertcone.94.old, and then rename vertcone.05 to
vertcone.94...that way the software will have no choice but to use the new
model file. I like to have both though, you you'll probably want to keep
that option.
Aside for a few select locations, I never really took a close look at the
difference between the two VertCon models....
I made a grid based roughly on the center of each of the 7.5min USGS Quad
maps for the eastern part of Florida. I then ran two sessions of CorpsCon,
first using the old, original 1994 Vertcon, then the 2005 CERP Geodetic
Control Network supported model. Each time, I used as an NGVD29 elevation of
0.00', and calculated the NAVD88 conversion. I then took the difference
between these two iterations and generated the surface model shown in the
attached files.
The file "Vertcon-Comparison.pdf" shows the difference between the results
that would be reached by using each of the two vertcon models. The range is
+0.15' west of Lake Okeechobee to -0.06' in Palm Beach county. Again, this
is the difference between the results obtained by each model. As an example
see file "VertCon-Comparison-Lake.pdf". At each data point are two text
annotations, the one in blue is the result from the original NOAA/NGS Vertcon
model, and the Red is from the USACE generated CERP-VertCon. One of the data
points in this file just at the west side of the lake has a red number of
-1.33, and a blue number of -1.18. What this means, is that for a published
NGVD29 elevation of 10.00', the original vertcon would return an NAVD88 of
8.82', while the new model would result in 8.67'...that's the 0.15'
difference.

I thought this subject too important to just send to the GIS Committee/User Group so I’ve included a bunch more of the membership out there in hopes of getting more people involved and informed on what’s going on in GIS and how it will affect surveying in the future.
Here is a link to the free on-line version of the “National Land Parcel Data – A vision for the Future”
http://www.nap.edu/catalog.php?record_id=11978#toc
I have also attached a PDF of the discussion earlier this year about this book on the Spatial Roundtable website http://www.spatialroundtable.com/
This is a very important issue that Surveyors need to take up and voice their opinion on in a unified manner. We need to proactively become part of the discussion and the direction that this data will be created, processed and used in the future. No matter what your level of understanding or use of GIS is, this could be a serious turning point in what surveying in the future will be.
GIS is growing by leaps and bounds and is pretty much an unstoppable force as to the question of “what’s next?” Changing technologies and the use of cloud web services and mash-ups involving thousands of servers and datasets across the globe connected together to act as one. Applications being written every minute of every day to work on GIS Servers, Phones, and multiple other devices to help us stay in touch in business and social networks.
What is our role as a Surveyor and Mapper? How are we going to stay the experts in measurements when GPS technologies and uses are becoming easier and easier for the everyday person to use and understand. How do we keep the expertise of being able to follow in the footsteps of those that came before us in defining the land and keeping the public interests at heart? We are losing our mystique and the expertise we have always had to keep us separated from the mainstream, so what are we going to do about it. Become involved and start reaching out to gain that knowledge you lack before it’s too late. Slow times are upon us, so there’s no better time to learn than now.
Please take the time to read through the on-line paper and the discussion and keep the profession in mind as to what our roles currently are and how that will change if we do not get more involved.
Regards,
Richard D Pryce, P.S.M.

The following field notes are very interesting and detailed (unlike today's field notes). They describe the contract with the crew, a Polaris shot in 1897 and much more. Field notes are our umbilical cord. But they are getting worse every year. In survey review, you always ask for the field notes. Too bad it is a lost art.

Are you an out-of-work surveyor trying to figure out how you're going to afford Christmas gifts this year? Do you know of someone else in that situation? The Matthews Co. Inc. and land surveyors from around the United States have teamed up to help bring Christmas to the families of 100 surveyors who are out of work due to the economy through a program called Surveyors Helping Surveyors 2009.

The US Army Corps of Engineers Jacksonville District added a grid that utilizes the CERP Geodetic Monuments in South Florida, follow Mr. Jeff Navaille’s (SAJ CofE) instructions below: 1) Unzip and copy these files to: C:\Program Files\Corpscon6\Vertcon Vertcon.zip 2) When you open Corpscon ver. 6.0.1, go to the set up screen and click on the vertcon tab. Click the radio button on "Custom Vertcon Data Set", and navigate to and select "vertcon.txt". 3) Now for me, this is where it gets interesting, because even though you have selected the customized grid file, it will not use this customized file in the calculations, even though it says its using it in the header of the
output file! 4) Here's where I exit the program and then start it up again...try it.

“A Land Remembered” by Patrick D. Smith published in the mid 80’s (I’d guess ’84 maybe). It is really a thinly veiled story of John MacArthur’s family. It describes in detail the cattle drives to Tampa and the gold payments and how that gold turned into the South Florida empire of the MacArthur Estates.

Last weeks map was a plat by the GLO in the patent. This weeks map ties in to that survey and extends it several townships to the South and it is in NAD27 State Plane, very high tech for the time. It also has a T.I.I.T.F. Resolution and field notes. The map is a Reconnaissance Survey. I’m not sure what that is, but if you follow the notes they set section corners like a survey or a dependant resurvey or a resurvey or even a boundary type survey. Read the field notes they are very interesting. If you’ve worked in or visited the park you will understand what they are talking about. I wonder if this is one of the first “Surveyor’s Reports”. Also there is a possible mistake with one of the corners, can you find it?
I don’t believe that the map is readily posted to any website. If you know of it please share it.
