MONDAY (8:30 AM - 10 AM) California Real Time Network (CRTN) What is the CRTN and how do I use it? This presentation will cover the California Spatial Reference Center (CSRC) California Real Time Network (CRTN). Presenters will discuss the CGPS network and infrastructure, CSRS published station coordinates, future expansion plans and California NGS CORS stations. The presenters will also cover how to connect to CRTN for RTK surveying and describe some various GNSS hardware and configurations as well as recommendations for RTK GNSS surveying utilizing CRTN. About The Speakers Rich Maher, PLS is a professional land surveyor with over twenty years of experience practicing in California. As the owner of KDM Meridian, over the past 12 years he has provided professional land surveying and mapping services in the public works sector, including numerous projects requiring the establishment of survey control through GNSS static and real-time methods. He regularly provides training and education in best practices in static and real-time GNSS surveying through his mentorship of employees at KDM Meridian and consulting support to other local firms and surveyors. As a consultant to the licensing board of California he has participated in all phases of development and execution of the California PLS exam. He is currently the secretary of the Orange County Joint Professional Practices Committee and the secretary of the Executive Committee of the California Spatial Reference Center. Dave Olander, PLS is a professional land surveyor and has been employed with Caltrans District 11 (San Diego/Imperial County) for over 20 years. He has worked in every capacity of Field Land Surveying work that Caltrans offers, throughout District 11. Currently he manages the District’s geodetic control and special projects. Additionally, he participates in various statewide panels charged with development and modification of Caltrans Survey standards, procedures and equipment issues. MONDAY (10:30 AM - 12 PM) NGS Update The mission of the National Oceanic and Atmospheric Administration’s (NOAA) National Geodetic Survey (NGS) is “to define, maintain and provide access to the National Spatial Reference System (NSRS) to meet our nation’s economic, social, and environmental needs.” NSRS is the nation’s system of latitude, longitude, elevation, and related data, models and tools, which provides a common, consistent, and accurate spatial reference system for a broad spectrum of users and applications. Technological GNSS developments as well as user requirements and demand have resulted in extensive efforts to maintain and modernize the NSRS. These changes are all designed to improve the accuracy and accessibility of the NSRS, to the benefit of all geospatial professions and activities.This presentation will describe the current status of the NSRS and will include information about the NGS network of GNSS Continuously Operating Reference Stations (CORS), the Online Positioning User Service (OPUS) utilities, and the online retrieval and updating options for geodetic control data. The current NAD83(2011) epoch 2010.00 datum realization and the corresponding geoid model (GEOID12A) will be described. Preparations are well underway for a major NSRS modernization makeover, to be realized in about a decade through a new generation of horizontal and vertical datums. Demonstrations of several interactive newer versions of NGS software will be given, including DSWorld, Vdatum (now does SPC conversions), NADCON, HTDP, and Translev for submitting Reset BM data. About The Speakers Marti Ikehara has been the California Geodetic Advisor for nearly 15 years, discussing the importance of datum tags and epoch dates in this geologically active state. She has also overseen nearly a dozen Height Modernization projects, and provided seminars about the relation between geodetic and tidal datums. Prior experience includes 18 years as a groundwater hydrologist with the US Geological Survey in Honolulu and Sacramento. William Stone is the NOAA/National Geodetic Survey’s (NGS) Southwest Region Geodetic Advisor. He assists the geospatial community throughout Arizona, Nevada, New Mexico and Utah—including public- and private-sector surveyors, GIS professionals, engineers, and earth scientists—with proper application of the National Spatial Reference System. Stone has been with NGS since 1989, and he previously worked for the Department of the Navy and the Defense Mapping Agency. He has a BA in Physics from Bowdoin College and an MS in Physical Oceanography from the Scripps Institution of Oceanography. He lives in Santa Fe, NM. CLSA NALS
MONDAY (8 AM - 10 AM) Mine Surveying: Photogrammetry This discussion will focus on fundamental concepts important to the mining field surveyor including: • Photo scale • Mapping scale • Size and placement of photo targets • Leeway in location of photo targets • Photo i.d. when a target is missing • Recommended field checks to verify the topo • Accuracy of the aerial topo • Overview of aerial mapping products including topo, DTM surface and orthophotography Mine Surveying: Incorporating Surveying into Exploration Surveying for open pit and underground mining • Uses in operation and design • 24/7 monitoring for safety • Procedures and processes About The Speakers Mitch Bartorelli is an Associate for Tri State Surveying, Ltd. and serves as the Project Manager for the Photogrammetry Service group. Mr. Bartorelli has been working in a responsible position in the photogrammetry, mapping and surveying field since 1989 and has been with Tri State since 1997. With Tri State, Mr. Bartorelli is responsible for photogrammetric operations including flight planning, aerial photography acquisition, film processing, analytical aero-triangulation and depending upon the project, digital terrain modeling, digital elevation modeling, planimetric mapping, topographic mapping and digital orthophotography. Mr. Bartorelli has conducted photogrammetric mapping projects for such clients as: U.S. Bureau of Reclamation, the U.S. Bureau of Land Management, the U.S. Geological Survey, the U.S. Department of Energy, the Nevada Department of Transportation, Sierra Pacific Power Company, Nevada Power Company, Newmont Mining, Comstock Mining and KGHM/Quadra FNX. 2013 marks the 35rd year for Marty Crook’s involvement in the surveying equipment industry. From alidades to zenith plummets, training from L.A. to Germany with manufacturers from AGA to Zeiss, Marty has been a part of the evolution of our current electronic environment. Today our positioning abilities rely on lasers, robotics, GPS, and handheld computers ruggedized for outdoor use. Having always been on the leading edge of technology, Marty continues to remind us that our current equipment is still based on the basic transit, theodolite, chain and strength of figure. MONDAY (10:30 AM - 12 PM) Mine Surveying: GPS 101 This non-technical presentation for field surveyors will focus in on some of the fundamental geodetic principles of GNSS survey technology: - GPS overview of sytem history, satellites, and equipment, - GPS epochs for CORS permanent base stations, - GPS Static accuracy and functionality, - GPS (Long Distance) RTK and functionality, - GPS Grid Distances versus GPS Ground Distances, - GPS Ellipsoid Heights versus Geoid Heights, - GPS Site Calibrations using a Geoid model, - GPS Site Calibrations – who, what, when, where and why, About The Speaker David Paul Johnson, PLS, started land surveying 30 years ago, when a Chainman “pulled a chain” all day. David has been a California Licensed Land Surveyor for more than 20 years. For the last 15 years, David has taught community college classes, presented conference workshops, and lectured throughout the western United States on: GIS, GPS, and Land Surveying. CLSA NALS
