Earth Engine is introducing
noncommercial quota tiers to safeguard shared compute resources and ensure reliable performance for everyone. All noncommercial projects will need to select a quota tier by
April 27, 2026 or will use the Community Tier by default. Tier quotas will take effect for all projects (regardless of tier selection date) on
April 27, 2026.
