Hey guys, great to see this community popping up on Lemmy. I am an earth data scientist with focus on remote sensing and a fan of OSM for years now. So far I only contributed minor stuff via StreetComplete, but now finally added my first building using the ID editor. It was surprisingly easy and I am super happy I could remove this blind patch from my neighborhood.
Just wanted to share my little success!
When you go to the OSM website, just click the edit button. You will have the option for a very nice 10 minute tutorial that shows you how to edit features, change lines (streets etc.) and drawing areas (e.g. buildings). You can try out how to change features without them being saved during the tutorial. I encourage you to try it out!
