In addition, resources available on the department’s web site will be discussed. Hydrographic Surveying: Overview and Current Licensing Requirements SPEAKERS: Mike Stecher, Jason Magalan Hydrographic surveying is a rapidly growing eld of surveying and mapping that encompasses underwater remote sensing techniques. Examples include bathy metric surveying, side-scan sonar mapping, sub-bottom proling, acoustic current measurements, acoustic scanning and geomagnetic sensing. Purposes include bottom elevation mapping, seaoor imaging, object detection, charting, benthic habitat assessment, structure evaluation and sub-surface sediment conditions. Each measurement technique has benetted in recent decades from rapid technological advancements in sensing and positioning, requiring operators to remain procient in a fast-growing eld. is presentation will, rst, explore the traditional measurements and techniques that are oen included in traditional hydrographic and marine geophysical surveying operations. Subsequently, a summary of ongoing conver sations will be presented that will describe the current state of professional licensure, and where hydrographers t within the realm of professional land surveyors and engineers. Legal Descriptions: Statutory and Case Law SPEAKER: Earl Morriss Remedies to Resolve Property Line Problems (CONT.) SPEAKER: John Stahl High School Program 1:00–2:30 pm Tips and Hints for Preparing Claims of Benecial Use SPEAKER: Gerry Clark is session, will specically discuss tips and pitfalls related to the preparation of Claims of Benecial Use reports and maps for both permits and transfers. Legislative Update SPEAKER: Darrell Fuller What is the OLC and What do They do with LiDAR? SPEAKERS: Jacob Edwards, Bill Burns Understanding Surveys, Descriptions and Plats SPEAKER: John Stahl High School Program 3:00–4:30 pm The Original Survey of the International Boundary: Summit of the Rocky Mountains to the Gulf of Georgia SPEAKER: Denny DeMeyer See description on page 10. How I Became a Rogue Lawyer: Ownership and Boundary Issues on the Rogue River SPEAKER: Jeanie Bricker e Oregon Court of Appeals decided Hardy v. State Land Board in October 2015, concluding that the Rogue River is navigable and state-owned downstream from Lost Creek Dam. Bricker represents the petitioners, landowners who challenged the state's assertion of ownership. Jennie will give the backstory behind this litigation and provide an overview of the legal issues aecting ownership of submerged and submersible lands in Oregon. Height Modernization Surveys with OPUS— Projects and Atmospheric Eects on GNSS Positioning SPEAKERS: Dan Gillins, Jihye Park In 2014, NGS released a web-based tool named OPUS—Projects for processing multiple static GPS observations involving multiple marks. is seminar presents an empirical research study on the accuracy of OPUS-Projects and compares its results with results obtained using Trimble Business Center (TBC). It discusses best practices for processing GPS data in OPUSProjects and shows how OPUS-Projects can be implemented for modernizing heights on dozens of benchmarks to a vertical accuracy of 2 cm or less at the 95% condence level. Although it is possible to obtain centimeter-level accuracy with GNSS, this seminar will also show that abnormal ionospheric behaviors, such as ionospheric scintillation at low/high latitudes or strong ionospheric gradient, can signicantly degrade GNSS positioning capabilities. It then presents a strategy for mitigating error in severe ionospheric environments. » continues on page 12
