THE OREGON GNSS USERS GROUP PRESENTS
HANDS-ON SURVEYING WITH UAS (DRONES)
The development of small Unmanned Aerial Systems (UAS) along with lightweight sensors and software have revolutionized aerial mapping. OGUG is pleased to provide Geospatial Professionals in Oregon a chance to witness these technologies in action.
Tuesday August 23, 2016 8:30 am – 4:00 pm
NW Eola Viticulture Center of Chemeketa C.C.
215 Doaks Ferry Rd.
Salem, OR 97304
Registration Fee: Members $25 / Non-members $75 PDH Credits: 6
(Hint: Consider becoming a member for $12!)
Coffee, pastries and catered lunch (sandwich) provided.
For those who attended the Geodetic Workshop provided by Michael Dennis, there is a new version of the presentation that was revised on March 17, 2016. The most significant revision to the handout is on p. 22 for computing distance using the local geodetic horizon approach. He corrected minor math errors on that page and also changed and added additional information. You can download the handout here (PDF). There is an accompanying PowerPoint presentation, but is too large to attach. You can go to this link and download it here.
There is also a Certificate of Attendance you can download here.
All Special Events will be archived here for future reference.
March 3, 2017 Announcement

What do you do when your horizontal control monuments are NAD 83 (1998), your field work is NAD 83 (2011) epoch 2010.00, and the client requires NAD 83 (1991) deliverables? Which geoid model should be used with the different horizontal datums? How do you set up a long-term project in light of the fact that new horizontal (geometric) and vertical datums will be defined and adopted by NGS within the next 8 years? How does all this work with the Oregon Coordinate Reference System low-distortion projections? What is the difference between NAD 83, IGS08, ITRF2008, and WGS 84? What software tools are available?
First come, first served for up to 150 registrants. Cost is $75 and includes buffet style lunch. Attendees will be emailed any handout materials a few weeks before the workshop and should be self-printed prior to your attendance. No handout materials will be provided at the workshop.
