Hello woodpeck! The aerial imagery here seems a bit outdated, so I also relied on local knowledge since I’m quite familiar with the area. What I mapped was actually the plot/house boundary layout planned by the NOIDA authority, not the exact building footprints, as the plots are structured that way in this region. That said, I understand OSM usually expects actual building outlines, so I relize i have misinterpreted, I'm currently in the process of mapping this particular sector and will correct them accordingly. I’ll also re-check the areas where sizes or overlaps seem off. I’m still relatively new to mapping, so I’d really appreciate any guidance on best practices. Thanks again!
