Hello aharvey,  

We want to ensure the best possible accuracy for our mapping efforts, especially in avoiding overlaps between water and buildings. While we can't control publicly available source materials in OSM, we can guide mappers to use the most suitable imagery references.  

To improve this process, could you share which **cities or AOIs (Areas of Interest)** you would like to focus on? If you’re aware of areas where Esri imagery is less reliable, please let us know so we can try to exclude those regions from our challenges.  

Your input will help refine our approach and ensure more precise mapping. Looking forward to your suggestions!  

Best regards,  
Kiran
