It hasn't been a week since I met OSM and Osmand. And I created all the beaches in a city from scratch. I added the important points in detail with their labels. I took long walks and it was fun.
A rectangles should be rectangular. You can assume a football field or similar sport field has right angles, so you should draw it as a rectangle. There is a built in tool for that. In the iD editor you used, select the field, rightclick-> Square, or press the Q key on your keyboard. This is usually true for semi detached houses as well. People like to build rectangles.
The place=locality tag is used to name an unpopulated location for which there is no extant feature to which the tag could be associated.
Maybe the translation is wrong in the editor for this item, I see you used Turkish language. If it's some kind of an empty plaza or paved place, use place=square (wiki) or highway=pedestrian + area=yes: a hard-surfaced, open pedestrian area: https://wiki.openstreetmap.org/wiki/Square
These are small problems, it's really nice, keep up the good work!
Pokemon GO recently introduced a new Pokemon from the Scarlet/Violet games, Wigglett. It only spawns in areas designated as beaches, and Pokemon GO primarily sources its map data from OSM. A lot of people don't have many beaches nearby, making it a pretty rare Pokemon.
Why would it be a plot twist, it's called armchair mapping, and the most common way of mapping
I have some random spots in the world where I draw buildings and paths regularly. I have no irl connection with them, I just randomly zoomed there once and bookmarked it. There is something relaxing, zen like feeling when you just trace houses and paths. Never intend to go there, but it's nice to create something. Maybe one day a guy will wonder who the hell draw his village in South Kongo, and why is it much more detailed than the regional capital
