GPS is actually very accurate, to about 30cm/11.8".
Any perceived inaccuracy will be the fault of the receiver (those made before 2018 aren't that accurate), or with the mapping software they contain.
My dad died in 2000 and my sisters and I were tasked by his wife (not my mom) to clean out a room in her house and I found a box with at least 20-30 folded maps. They had done lots of RV traveling. I thought it would be fun to look at them but for some reason, she (or someone else) tossed the box away and all the maps went bye-bye. I was sad that I wouldn't get to look at them.
I have an atlas from 1910 that my grandson and I have pored over for hours. It's interesting to see the many changes in countries, but also fascinating to read the population numbers for cities around the world. It lists every U.S. town having a population of 5,000 or more. At that time, Grand Forks, ND had more residents than Miami, FL. Sort of blows your mind.
