XXII FIG INTERNATIONAL CONGRESS

MAPPING AND GIS WITH GPS
Room: Balcony C
Saturday, April 20
This is also offered Sunday, April 21
8:30 am – 3:30 pm
PDH Hours: 6
FL CEP: 032 134
Course Level: Introductory
Workshop Limit: 30
This course will utilize GPS to collect feature and attribute data for transfer
to a Geographic Information System. The course will show the participant
how to create a data dictionary from scratch or from Shape files.
The created dictionary will be taken into the field to collect point, line and
area data. Data will be collected in real-time and for post-processing.
This is a hands-on course in which the participants will be collecting the
data. The collected data will be corrected if necessary and displayed in
the classroom. Collected data will be transferred to a GIS for further display.
Files will then be sent back to the receiver and to the field for data
maintenance.
This course is designed for GIS professionals as well as other surveying
and mapping professionals
Instructors: Brian McInnis & Elwin McLachlan Trimble Navigation

ADJUSTMENT OF SURVEYING ERRORS
BY LEAST SQUARES
Room: B North 1
Saturday, April 20
1:30 pm – 5:30 pm
PDH Hours: 4
FL CEP: 032 54
Course Level: Advanced
In the collection of surveying measurements, after care is taken to discover
and remove the effects of mistakes and systematic errors, irregularities
usually remain in harmonizing the observed measurements with
known geometrical conditions. Simple rule-driven adjustment methods
yield conflicting results when used with interconnected level loops and
traverses, and unpredictably degrade the quality of the observed measurements.
The geographically larger, geometrically more complicated
surveys of increasing precision possible with modern survey equipment
and methods require adjustment techniques that are theoretically based,
and capable of simultaneous consideration of all observations. Least
squares routines have long been known to be based on a solid theoretical
foundation for the analysis and adjustment of random errors, but
have never been easy to perform. This workshop seeks to furnish theoretical
understanding and demonstrate computer-aided application to
common survey types including level networks, horizontal survey measurement
networks, and GPS baseline networks. The textbook for this
workshop is Adjustment Computations: Statistics and Least Squares in
Surveying and GIS. Participants in this workshop should have attend the
workshop "Surveying Errors and their Analysis."
Intended Audience: This workshop has been presented at several
state conferences around the United States and appeals to practicing
professional surveyors who are involved in management and adjustment
of surveying measurements.

BUYING AND SELLING SURVEYING AND
SMALL ENGINEERING COMPANIES
Room: B North 2
Saturday, April 20, also offered on Monday, April 22
1:30 pm – 5:30 pm
PDH Hours: 4
FL CEP: 032 132
Course Level: Introductory
This course covers the very important information that a buyer or seller
needs to know to successfully complete the transaction. The course will
help answer questions such as: When is the right time to buy or sell?
How do I get my company ready to sell? How much is the company
worth? How do buyers and sellers find each other? How do I limit taxes
on the sale of a company? Do I meet IRS Rules on the value of company
stock? How can I make sure the transition is a success? How to preserve
my good name after the sale?
Also, information will be provided on how to increase the value of a business.
What roll should a banker, attorney, or accountant play in the purchase
or sale, and common sense rules that help you make sure you are
making the best deal that will make the purchase or sale a success.
Instructor: Milton E. Denny, 3001 Inc.
INTRODUCTION TO USING CORS
(CONTINUOUSLY OPERATING REFERENCE STATIONS)
Room: B North 5
Saturday, April 20
1:30 pm – 5:30 pm
PDH Hours: 4
FL CEP: 032 133
Course Level: Intermediate
This workshop is designed for persons who use Global Positioning
System (GPS) data for post-processing applications. The National
CORS system comprises a network of more than 230 sites, each containing
a geodetic quality receiver whose data are freely available via the
Internet. Topics include a description of CORS information and its various
applications (positioning, GIS development, remote sensing, etc.),
how to access CORS information, and how to use publicly available utilities
for processing GPS data.
Instructors: Mark Eckl, & Richard Snay, National Geodetic Survey
Sunday • Half-Day Morning Workshops
ORTHOPHOTOGRAPHY
Room: Maryland B/C
Sunday, April 21
8:30 am – 12:30 pm
PDH Hours: 4
FL CEP: 032 5
Course Level: Intermediate
An orthophoto is an aerial image that has been rectified in such a way that
it is made to possess characteristics of a line map. The rectification process
is performed by combining photogrametric principles with digital elevation
models (DEM) data. Orthophotos have been used for many years by a
diverse group of users. Recently, orthophotos have been re-discovered by
GIS/LIS users and are rapidly becoming a leading form of base maps.
This seminar will explore how orthophotos are made, accuracy and quality
aspects of this data, advantages and disadvantages. A discussion on the
role of surveyors in compiling this form of spatial data will also be included.

Technology (NJIT)
