Nightmare on GIS Street: GNSS Accuracy, Datums and Geospatial Data

What is the difference between a reference frame, a datum and a realization?

Why is timestamping coordinates important?

What is the difference between NAD83 CORS96 and NAD83 2011?

Why don’t ESRI products support these concepts?

If you are like most people, it is all a nasty-ugly blur.

Wouldn’t it be great if someone make a simple video with really smart presenters that started to explain all of this?

Someone (Eric Gakstatter) did! And the video is great! It features Kevin Kelly the Geodesist from ESRI (who would have guessed that they had one?) Craig Greenwald and Michael Dennis from NGS who absolutely knocks it out of the park on this webinar.

This [ link ] should get you the webinar recording. You have until September 18th 2013 to watch it. Do It Now! I can not recommend this webinar highly enough! It is fantastic.
