In Switzerland, depending on the canton, there are different geoinformation systems that are more or less publicly accessible. Luckily, here in the canton of Zurich we have one of the best in the country: GIS Browser Since I work in an architectural office, I am familiar with coordinates and cadastral plans. From this portal we can download the exact borders, buildings and more and use them in our CAD systems. This data was officially measured and entered by the geometers. So these are accurate to the cm!
So I converted the coordinates into our Swiss system and then entered them into this GIS browser. Then I was able to measure the distance to the corner of the house pretty accurately. I saw that the point was outside the building. I put all the information on a piece of paper for a possible no batteries success.
I then drove close to the address during my lunch break. A short walk around the building and I was able to claim success with a clear conscience!
Just out of curiosity, I opened the Geohash Droid app and looked at the position. I was 4.5m off the mark! And the point was finally in the building... Now this makes me uncertain for future expeditions, as my position was confirmed with the geomatics instruments, but was wrong with my smartphone.
