Webinar: GPS on Benchmarks – January 2021


Category: Tag:


This webinar will explore the data that NGS has from California using the Web Map Application and the Progress Dashboard. We will look at the existing data gaps and encourage regional collaboration to collect and submit data by the December 31, 2021 deadline.

It will also focus on the dual benefits of gathering GPSonBM data; computing the 2020.0 Reference Epoch Coordinates and their subsequent use in creating the transformation grids between NAVD 88 and NAPGD2022.
