    i wish i i had a prof who i could interrupt like that thanks for the simple explanation

    I would love to see this explained in 3D with 3D animations to explain where the grid is situated and the ellipsoid and ground and actual surveying to make it more clear.

    Should you be using a scale factor and coordinate systems for total station data? Or is it appropriate to use a scale factor of 1.00? My understanding was that if your are using ground scaled coordinates for your instrument and backsight you will be measuring ground distances.

      Would love to get some input on this question as well.

      They must not know. 🤷‍♂

      the question is if we insert any scale factor other than 1.000000
      would it affect out measurements
      For example if we measure 100m with 0.9996 >>> will we get 99.96
      if it is , it means we will face problem

    felicitaciones por el video, por favor con respecto al titulo del video podrian sugerir algun libro que se pueda descargar? a su vez desarrollar un video en TBC en la conversion de coordenadas locales a plana y viceversa. Saludos.

      I watched this video and did the process you mentioned. My point I selected was my middle point between to other GNSS VRSS observed control points. All three points were observed by GNSS RTK. When you do the local site conversion to the point you choose as the CP as you did 12, the coordinates do not change after the process. So my question is how is that putting CP 12 in your case on ground coordinates. I don't think it does, it's still grid. A true GRID to GROUND conversion for three new Control Points in my case we be that all three points would have coordinates that differ somewhat equally from their GIRD coordinate.
