Geospatial Reference Videos

We can’t always assume that the earth is flat for all of our geospatial surveys. The use of GNSS certainly does not assume this to be the case.

So I have been doing some research this week on geodesy and have come across a number of excellent resources that I wanted to make you aware of. I think it was reading the Red Atlas that got me thinking about map projections, coordinate systems and datums.

The first is the home page for the National Geodetic Survey. There is a wealth of geospatial information available here and it is not just for the hard core geodesists. There are links here to pages on OPUS, CORS, state plane coordinates, land surveying, leveling, datums and transformations and much more.

A second landing page is found at MetEd which is a free collection of hundreds of training resources intended for the geoscience community.

There are some 19 videos available on this page including topics on geodetic control, foundations of GNSS, transforming heights between vertical datums, best practices for GNSS, survey feet vs. international survey feet – the list goes on.

If you are feeling like you need a review, or want to learn about some challenging geospatial topics there is a wealth of information at your fingertips on these pages.
