I am halfway done reading, "GPS and GNSS for Land Surveyors Fidth Edition", which I bought to better understand the survey issues we were having with surveys and data on a project I was on in Saudi Arabia for 6 months last year and 2 months this year. I was a physics major and I have to say surveying is a lot more complicated than I had ever imagined. Realizing that relative height data from one point to the next is straightforward, but that a simple elevation reading is based on MSL and what area in the world you're in for your reference are just a few of the variables that go into the craft of surveying. I really went down the rabbit hole, but I've learned so much and I am now hooked on taking it much further.

In my high school in 1980, we took a 2-hour survey/questionnaire filling in circles with a #2 pencil, and we we waited 3 to 4 weeks to get the results of what career we were suited for, and mine was cartographer! I imagine there were humans and machines doing the analysis back then, but maybe I should have followed that path!
