USGS Flow Photo Explorer is still going and growing!

The Flow Photo Explorer (FPE) platform continues to grow rapidly as a national resource for using imagery to monitor environmental conditions. As of early December 2025, FPE now supports more than 350 users, operating across more than 600 monitoring sites. The database has expanded to over 12 million images, 800,000 annotations, and approximately 160 trained models, reflecting accelerating engagement from federal, state, tribal, academic and nonprofit partners.

Please see two critical updates below. Thank you for your continued support and contributions, we’re looking forward to many exciting improvements in the year to come!
