    Every episode again I am amazed about the variety of landscapes and about the wealth of knowledgeable and friendly people you let us meet through your videos. Every episode again we learn a tiny bit more from the endless things there are to know about the geology of Washington. And every episode again shows us your love for geology and the Pacific Northwest. I can't wait to view the Baja-BC A to Z series as well. I love to learn alongside you about Washington's geology. Wish I could visit one day (or preferably more!)

    I worked on flood control pumping stations on the Washington coast for many years and a couple of them had those bronze geodesic markers inserted into the heavy/thick concrete structures of the pump station base. A few times we had to unlock gates for people who needed to get measurements from those survey markers. Fascinating stuff!

Many many moons back my late Dad worked with Boeing developing GPS for the military at that time. Cool how far folks have run with it and how useful it is today. We can see how much the PNW is rotating and I can deliver food with UberEats, and you guys can see if the magma is lifting or not or another bit of Teanaway is slipping. Love it.

    PANGA is great for land surveyors to fill in the gaps.
    Generally, in order for a land surveyor to get centimeter accuracy from post processed GPS, a continuously operating base station (CORS), like PANGA, needs to be within 12 miles of the other receiver. This is mostly because anything greater than 12 miles will not share the same ionospheric radio conditions as much.

    • @briane173
      @briane173 2 года назад +1

      There's a website I've seen but now I have to go look for it because I didn't bookmark it; but it's an operation out of Nevada that collects data from GPS arrays across the West Coast and it offers up graphs of not just horizontal but also vertical movements at each site, which is VERY interesting when looking at stations along the Cascadia Margin. The movement is measured in mm but the vertical movement from the coast being pushed up and in by the subduction occurring is graphed and it's indisputable that the vertical and inward movement exists, is going on in real time, and will at some point provide a measurement of how much rebound there will be during the next subduction earthquake.

    I’ve been wanting to ask this question for two years and Walter is touching on my question so here goes… I bought my house in Spokane County 30 years ago and if I understand correctly our plate has moved about 30 inches Southwest since I bought the property. If I had a surveyor check my property corners now wouldn’t he or she say that my property corners are really 30 inches Northeast of where I think they are? Walter said something about “relative to the entire state” do surveyors correct for plate movement since the original survey? It must get very complicated if they do.

Makes for some interesting platting but it's like what other choice do geodesists have than to trace property lines to account for movement?

    10:19 extra- the vertical difference might trigger, but that is the 'weakest' in certainty. Latitude and longitude will be good because of the high order locations of fiducial ground stations, but broadcast vertical is subject to imperfections in the geoid model that is used in calculating 'height' from the broadcast ephemeris. I would think they are post-processed with the precise ephemeris and get the best positioning. Lots of mumbo-jumbo there, but it comes down to that the vertical is the least accurate measurement.

    • @davidpnewton
      @davidpnewton 2 года назад

      At its most approximate earth is a sphere.
      Next most approximate is an oblate spheroid. In other words the rotation of the earth makes it bulge out at the equator.
      Then we have to begin thinking about ocean basin v continental crust.

    • @gnomespace
      @gnomespace 2 года назад

      ​@@davidpnewton yes, and the oblate spheroid' is what is used in the broadcast ephemeris as the lumpy potato geoid causes variation in the actual altitude of orbital epochs vs broadcast. Fine for navigation, but for good elevations you really need to post-process with the precise ephemeris which is adjusted after the fact.
