Good video, often find myself explaining what the accuracy actually means now I can use this video 😂

Really pleased to see a reference to the specific ISO spec in the article.

thank you, i nearly forgot the error calculation :-)

Your content has been very helpful. I've been soaking up so much knowledge from your channel. It really simplifies the complexities of the surveying world for me, making it much easier to understand. Thanks for all the valuable insights!

i really liked your video! but would you also consider to use metric as well as imperial units for international viewers? thanks

[andrej_guitars]

Great video, many thanks for sharing! Love your error propagation program, I will look at creating a similar spreadsheet!

how far can i be from total station to do a topo accurately?

[toddhorton]

Can you provide a link to the white paper?

Please somebody reply to me, when I set up the TS resection and stake out a points and move to another location and set up the TS with the same standard deviation and stake out the same point give error in the point location till 5 cm . What is the reason ?!.

[hermangelderblom]

Where can i find this program? Can it be converted to display metric?

[painteur]

Great video . Can you make a video on how to run a survey firm and how to find clients .

Sorry but how accurate is a 5" at 100m not including other errors? I was told 4mm, 2mm at 41m. Could find it in your video
