Installation Procedures
INSTALLATION PROCEDURES
Corpscon6_update File - This file should be downloaded only if you have a downloaded Corpscon prior to April 26, 2005. If the install files were downloaded after April 26, 2005, then they already include the corrected files. To install this update, extract these files to the directory in which Corpscon 6.0 was installed. If the default installation was used, this directory is 'C:\Program Files\Corpscon6\'. If prompted, overwrite the existing files in the directory. You cannot run Corpscon with this zip file alone. You must have already downloaded one of the distributions listed below.
Issues Resolved:
4/26/05 - Error in resolving certain USNG zones. Unit conversion problem when using International Feet in Vertical conversions.
There are five Corpscon setup (install) files:
1. corpscon_complete.exe (104 MB, 140 MB installed) - installs all the Geoid and Vertcon data files, including Alaska (don’t recommend this without high speed connection and still might take a while)
2. corpscon_conus_geoxx.exe (84 MB, 115 MB installed) - installs all the Geoid and Vertcon files for conversions within CONUS
3. corpscon_conus_geo03.exe (42 MB, 60 MB installed) - installs only the Geoid03 and Vertcon files for conversions within CONUS
4. corpscon_base_alaska.exe (7 MB, 20 MB installed) - installs only the files for horizontal conversions (no Geoid or Vertcon data files), including Alaska
5. corpscon_base_conus.exe ( 6 MB, 19 MB installed) - installs only the files for horizontal conversions (no Geoid or Vertcon data files) within CONUS only.
To install Corpscon, run corpscon_*.exe (* = one of the options listed above) from CD or from the directory on the local hard disk where the program was downloaded. Follow the prompts in the setup program to complete installation. Geoid, Vertcon, and other data files may be downloaded separately and copied to the appropriate directory by following the program directory structure listed below if downloading an install file other than the complete (first option above).

Their standard unit of measurement is the vara (33 1/3”). They also use a League, a Labor, a Sitio in their descriptions. What is most interesting is that land was formed under Spanish Law(1720-1821), then Mexican law(1821-1836), then Texas as a Sovereign Nation(1836-1845), then as part of the US. With each change they respected the previous laws so when you look at a deed, you have to see what year it was granted.

Have you been to McDill Air Force Base in Tampa? If so you’ve traveled Dale Mabry drive. I was born at Mc Dill Air Force base in Tampa and lived off Dale Mabry Drive. I thought that Dale Mabry Air field was the original name for Mc Dill, but it wasn’t it what’s now the Tallahassee airport.

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.

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.

George Washington's Thanksgiving Proclamation
(1789)
Whereas it is the duty of all nations to acknowledge the providence of Almighty God, to obey His will, to be grateful for His benefits, and humbly to implore His protection and favor; and Whereas both Houses of Congress have, by their joint committee, requested me "to recommend to the people of the United States a day of public thanksgiving and prayer, to be observed by acknowledging with grateful hearts the many and signal favors of Almighty God, especially by affording them an opportunity peaceably to establish a form of government for their safety and happiness:"
Now, therefore, I do recommend and assign Thursday, the 26th day of November next, to be devoted by the people of these States to the service of that great and glorious Being who is the beneficent author of all the good that was, that is, or that will be; that we may then all unite in rendering unto Him our sincere and humble thanks for His kind care and protection of the people of this country previous to their becoming a nation; for the signal and manifold mercies and the favorable interpositions of His providence in the course and conclusion of the late war; for the great degree of tranquility, union, and plenty which we have since enjoyed; for the peaceable and rational manner in which we have been enable to establish constitutions of government for our safety and happiness, and particularly the national one now lately instituted' for the civil and religious liberty with which we are blessed, and the means we have of acquiring and diffusing useful knowledge; and, in general, for all the great and various favors which He has been pleased to confer upon us.
And also that we may then unite in most humbly offering our prayers and supplications to the great Lord and Ruler of Nations and beseech Him to pardon our national and other transgressions; to enable us all, whether in public or private stations, to perform our several and relative duties properly and punctually; to render our National Government a blessing to all the people by constantly being a Government of wise, just, and constitutional laws, discreetly and faithfully executed and obeyed; to protect and guide all sovereigns and nations (especially such as have show kindness to us), and to bless them with good governments, peace, and concord; to promote the knowledge and practice of true religion and virtue, and the increase of science among them and us; and, generally to grant unto all mankind such a degree of temporal prosperity as He alone knows to be best.
Given under my hand, at the city of New York, the 3rd day of October, A.D. 1789.G. Washington
Abraham Lincoln's Thanksgiving Proclamation
(1863)
The year that is drawing towards its close, has been filled with the blessings of fruitful fields and healthful skies. To these bounties, which are so constantly enjoyed that we are prone to forget the source from which they come, others have been added, which are of so extraordinary a nature that they cannot fail to penetrate and soften even the heart which is habitually insensible to the ever watchful providence of Almighty God. In the midst of a civil war of unequalled magnitude and severity, which has sometimes seemed to foreign States to invite and to provoke their aggression, peace has been preserved with all nations, order has been maintained, the laws have been respected and obeyed, and harmony has prevailed everywhere except in the theatre of military conflict; while that theatre has been greatly contracted by the advancing armies and navies of the Union. Needful diversions of wealth and of strength from the fields of peaceful industry to the national defense have not arrested the plough, the shuttle, or the ship; the axe had enlarged the borders of our settlements, and the mines, as well of iron and coal as of the precious metals, have yielded even more abundantly than heretofore. Population has steadily increased, notwithstanding the waste that has been made in the camp, the siege and the battle-field; and the country, rejoicing in the consciousness of augmented strength and vigor, is permitted to expect continuance of years, with large increase of freedom.
No human counsel hath devised nor hath any mortal hand worked out these great things. They are the gracious gifts of the Most High God, who, while dealing with us in anger for our sins, hath nevertheless remembered mercy.
It has seemed to me fit and proper that they should be solemnly, reverently and gratefully acknowledged as with one heart and voice by the whole American people. I do therefore invite my fellow citizens in every part of the United States, and also those who are at sea and those who are sojourning in foreign lands, to set apart and observe the last Thursday of November next, as a day of Thanksgiving and Praise to our beneficent Father who dwelleth in the Heavens. And I recommend to them that while offering up the ascriptions justly due to Him for such singular deliverances and blessings, they do also, with humble penitence for our national perverseness and disobedience, commend to his tender care all those who have become widows, orphans, mourners or sufferers in the lamentable civil strife in which we are unavoidably engaged, and fervently implore the interposition of the Almighty Hand to heal the wounds of the nation and to restore it as soon as may be consistent with the Divine purposes to the full enjoyment of peace, harmony, tranquility and Union.
In testimony whereof, I have hereunto set my hand, and caused the seal of the United States to be affixed. A. Lincoln
