Here are the biography's of our scheduled presenters for this years conference.   As presenters make their material available, we will post it on our conference material page.

Mitch DuryeaMitch Duryea, PLS - President: - Originally from Southern California, Mitch began his professional surveying career in 1984. He has spent his career in private practice specializing in the Legal Principles of Boundary Surveying and Mapping. Mitch has a B.S. in Surveying and Photogrammetry from Fresno State University and a M.S. from Kaplan University. He started Duryea & Associates in 1993, and as President, is responsible for client development, customer service, and quality control. Mitch is licensed in Washington, Oregon, California, Idaho, Nevada, New Mexico, Oklahoma, Hawaii and South Dakota. In addition, Mitch has taught various workshops and seminars for LSAW, PLSO, CLSA, and an Adjunct Faculty with the Oregon Tech Geomatics Department, where he specializes in the Boundary Law courses.

Dennis GelvinDennis Gelvin:  the president of the Olympia Philatelic Society, has been surveying since 1966, is licensed as a Washington State Professional Land Surveyor, has been licensed in 10 states, holds an appointment as a U.S. Mineral Surveyor, and is a long time philatelist (that’s the nickel word for stamp collector), and has, through philately managed to relate the profession of land surveying to all 45 U.S. Presidents. 

This will be a lighthearted tour through a small part of American history.

Dr. Jan Van Sickle: 

 currently working on autonomous driving at Here Technologies. He was the architect for the GIS Center of Excellence at Pacific Gas and Electric. He has many years of experience in GIS, GPS, surveying, mapping and imagery. He has advised Anadarko, IHS Energy, Chesapeake, Microsoft, Intermap, Jeppesen, Geoeye, Hess, Laredo, Enserca, Digital Globe and others in geospatial matters.

He began working with GPS in the early 1980s when he supervised control work using the Macrometer, the first commercial GPS receiver. He created and led the GIS department at Qwest Communications for the company’s 25,000-mile worldwide fiber optic network. He also led the team that built the GIS for natural gas gathering in the Barnett Shale. He has led nationwide seminars based on his three books, GPS for Land Surveyors, Basic GIS Coordinates and Surveying Solved Problems. The latter book was serialized in the magazine POB. He led the team that collected, processed and reported control positions for more than 120 cities around the world for the ortho-rectification of satellite imagery now utilized in a global web utility. He managed the creation of the worldwide T&E sites for two major earth observation satellites (Geoeye I and Geoeye II) which are used for frequent accuracy assessments.

He conducted a spatial accuracy comparison study for Digital Globe in Durban, South Africa, Seoul, South Korea and Rio De Janeiro, Brazil. He created an imagery-based system of deriving road centerlines that meet the stringent Advanced Driver Assistance specifications and developed a method of forest inventory to help quantify that depleted resource in Armenia. 

He assisted the supervision of the first GPS survey of the Grand Canyon for the photogrammetric evaluation of sandbar erosion along the Colorado. 

 He has done 3D mapping with terrestrial photogrammetry and LiDAR as well as Building Information Modeling. He was involved in the creation of a BIM of the White House in Washington DC. He was a member of the team of authors for the Geospatial Technology Competency Model for the Department of Labor. He has conducted training at the NAVCEN in Alexandria for the USCG. He has provided technical assistance in the reconstruction of the geodetic network of Nigeria. He has managed the gravity/magnetic and hyperspectral/multispectral analysis of Borzon VII a concession block in the South Gobi in Mongolia. 

He writes the From Scratch blog for the Spar Point Group. He has been asked to contribute a chapter on Satellite-based Surveying Technology to the update of the more than 30-year old American Society of Civil Engineers (ASCE) Engineering Surveying Manual of Practice and course work on GNSS to the American Association for Geodetic Surveying (AAGS) Geodetic Certification Program. He has been a featured speaker at many conferences including MAPPS, GITA, the Institute of Navigation (ION) Annual Meeting. He delivered the 2010 keynote at the ESRI UC in Imagery and Remote Sensing and the 50th Texas Society of Professional Surveyors Conference. He is an Assistant Teaching Professor at Penn State University and teaches at the University of Colorado Denver. He was formerly on the board of RM-ASPRS, was the vice-chairman of GIS in the Rockies and was the founding chairman of the US West chapter of the Americas Petroleum Survey Group. Jan earned his Ph.D. in geospatial engineering from the University of Colorado. He has been a licensed professional Land Surveyor for thirty-six years, is currently licensed in Colorado, California, Oregon, Texas, North Dakota, West Virginia and Pennsylvania.
