About the Wallkill River UAV Library
This page organizes the supplied Wallkill-area UAV orthomosaics as an interactive chronological image library, together with NYSDEC NYHABS confirmed HAB reports from 2025 along the Wallkill mainstem.
What you can explore
- Date-grouped UAV survey layers
- Named locations and flight dates
- Overlapping imagery, with newer layers drawn above older imagery
- Nine confirmed 2025 HAB reports (Sturgeon Pool, Rifton, Perrine’s Bridge)
How to use the page
- Select an orthomosaic to change its visibility.
- Use Show All to review spatial coverage across the collection.
- Toggle 2025 HAB reports on the map, or tap a report to zoom to it.
- Pan and zoom to inspect shoreline, channel, floodplain, and surrounding land features.
Purpose: The library preserves the original flight-by-flight dashboard while connecting drone imagery to WaterInsight stewardship and 2025 bloom records. HAB markers are historical NYHABS observations, not a current advisory. Imagery should be interpreted with field observations.
