Presented by William Stone, NOAA’s National Geodetic Survey
OPUS-Projects is an enhanced version of the popular NOAA/National Geodetic Survey utility, the Online Positioning User Service (OPUS). It is a free, Web-based GPS multi-baseline processing and least-squares network adjustment package, providing simple visualization, management, and processing tools for survey projects including multiple survey marks and occupations. OPUS-Projects is a natural extension of OPUS, allowing surveyors, engineers, and other geospatial professionals to position campaign-style GPS observations (geodetic networks) at a high level of positional accuracy, often achieving cm-level uncertainty relative to the North American Datum of 1983 (NAD83) and the North American Vertical Datum of 1988 (NAVD88).
By attending this workshop, you should have enough information to successfully use OPUS-Projects for your own geodetic network projects. The training is 1.5 days in duration, and by attending the full workshop you will become an authorized project manager for OPUS-Projects, allowing you free access to the program. The workshop includes both instructor lectures and hands-on participant work with a sample training project (each participant will be provided their own copy of the project), which demonstrates various capabilities of OPUS-Projects, including the ability to enhance a project’s elevation accuracy by occupying published vertical control stations. You are also welcome to bring your own GPS project data (survey-grade, L1/L2 GPS data) for processing during the workshop (the instructor can provide further details). You must bring a WiFi-enabled laptop computer with a current generation Web browser. The workshop will include an overview of geodetic concepts pertinent to optimal use of OPUS-Projects and other GPS-related applications. The instructor will provide further details to all registrants prior to the workshop.
