Get It Surveyed: ESRI Surveying and Engineering GIS Summit

July 22, 2010By

I believe that if you attend the ESRI SEGS and UC conferences just one time, your vision of surveying, engineering, construction, and GIS will change forever. I know it sounds like an advertisement from ESRI, but I think my pitch is even better than theirs. Seriously though, there are so many people presenting so many different ideas, and they are all related to the kind of geographic data you work with on a regular basis. read more

ACSM/GITA Conference Coverage

May 4, 2010By

The annual ACSM (American Congress on Surveying and Mapping) isn’t what it used to be. Attendance was way down and the number of exhibitors is way down.

It’s been a tough couple of weeks for SBAS (Satellite-Based Augmentation System), namely the USA’s WAAS program and India’s GAGAN program. WAAS and GAGAN have taken big hits recently that threaten the integrity of the programs. Both events were totally unexpected and are causing disruptions of GPS correction services. read more
