Astronomical Observations of the Southwest by Chris Chavez
Astronomical Observations of the Southwest presentation is a trip back in time to see how surveyors, navigators, astronomers, explorers, and cartographers observed celestial bodies, which includes the Moon, Stars and the Sun for the purpose of finding direction, establishing coordinates, and to tell the time of day and year. This presentation will also include two significant aspects, the astronomical marker at Chaco Canyon and the Dominguez-Escalante Expedition of 1776 in which more than a dozen astronomical observations were made. The field notes of the observations were taken by Fray Silvestre Velez de Escalante, a Franciscan Friar, with amazing detail. This Expedition took place at a time in which the Declaration of Independence was being drafted giving birth to the United States. In addition, this presentation will also briefly cover a few examples of real-world applications using Spherical Trigonometry, Geodetic Astronomy, and time calculations.
Boundaries and Adjacent Properties – Skelton Revisited by John Stahl
The Legal Elements of Boundaries and Adjacent Properties by Ray Skelton is a foundational text offering learned and practical studies, informed methodically throughout by federal and state appellate and supreme court decisions, on the practice of land surveying. Skelton’s unique coverage of land surveying principles and boundary laws provides a thorough perspective on the rules, reasons for the rules, and the application of the rules governing the surveying professional’s boundary location decisions. Through presentation, discussion and case studies, this seminar will help the professional land surveyor learn and discern the legal basis for their boundary decisions.
CFEDS Standards of Practice by Glen Thurow and Tasha Huhta
The CFedS Standards of Practice provide the operational requirements for CFedS in both Federal and State Authority surveys. In addition to the standards, an in-depth review of the CFeds Program Handbook will also be covered. Current CFedS who attend and pass a related quiz will receive one continuing education credit.
This presentation will also interest those individuals who contemplate becoming CFedS in the future and wish to improve their professional credentials.
*Note: CFEDs Credit will be available for this course at a 50% saving in cost! Each 4 hour session is $25 for 1 CE credit (normally $50 for each credit). If you attend both the morning and afternoon sessions, you will receive 2 CE credits for $50.
You do not have to pay for CFedS credit to attend. Only those wishing to receive CFedS credit will need to pay the extra charge at registration.
Concepts and Computations in the PLSS by Glen Thurow and Tasha Huhta
This course will be a refresher on some basic mathematical concepts operating in the Public Land Surveying System, including an understanding of lines of constant bearings and lines of constantly changing bearings, calculation of forward and reverse bearings, and GLO plat interpretations.
This course will also review the concepts of parenthetical calculations and the relationships between parentheticals and areas, with particular emphasis on non-standard and fractional sections. Participants are urged to bring a calculator to this presentation.
Ethics by John Stahl
This course will provide a thorough review of the Maxims of Jurisprudence found mentioned throughout our case law history and even codified in statutory form in a few states. These maxims form the conceptual foundation of our legal justice system and encapsulate the ethical considerations woven into the fabric of our modern law. Studying these maxims will bring a fresh perspective to the ethical premise upon which our land tenure system is based. We will review the ancient English and Roman influences on our modern law. We will review the direct correlation between the maxims and the land boundary principles applied when making modern land boundary determinations.
Photogrammetric Processing of Planetary Images by Dr. Elaksher Ahmed
In this presentation, we will go over a brief historical background of photogrammetry and how it developed. We then will introduce the different imaging systems and the principles and geometry of aerial image acquisition and stereo viewing.
The pipeline for photogrammetric processing of images will then be presented including bundle adjustment, ground point surveying, image matching, DEM extraction, and least squares refining techniques. Next, we will present different
platforms including orbital satellites that orbit our Earth, the Moon, and Mars. We will present the concept of mapping the Mars surface with Hirise images and MOLA data. In addition, we will present different geospatial products used by NASA to understand the Earth and other planets and how these products are produced using photogrammetric techniques.
