Stay informed about the latest developments, improvements, and announcements shaping the hydroweb.next platform.
Dear users,
You can now draw bounding boxes or polygons on the map to use them as Where filter in your research.
Click the square-shaped icon at the bottom of the right bar in the Map view and draw your own polygon to define your spatial filtering.
Dear users,
You can now directly set the map visualization time window (the purple clock and temporal range at the bottom of the map view) by manually clicking and dragging the range with the mouse. You can still use the initial form approach for long window. Check the dedicated section in the On Boarding Tour to better apprehend this new functionality.
Dear users,
A new functionality has just been deployed on our platform: the "Layers" drawer, accessible from the Map View. It allows you to directly manipulate and re-organize the several layers in your workspace. This panel complements the "Workspace" panel.

Try it out and tell us what you think.
Dear Users,
Welcome to the newly redesigned hydroweb.next website!
Our fresh look is all about delivering a clearer, more intuitive browsing experience. While the redesign focuses primarily on usability, the core features from the original version have been largely re‑implemented, so you’ll find everything you relied on—now in a cleaner, easier‑to‑navigate format. This isn’t the end of the story. Our development team will keep building on the platform, adding new capabilities and improvements over time.
We’d love to hear what you think. Please share your thoughts through the new “Give Us Feedback” tab—we’re excited to evolve the site together with you.
Signed, the hydroweb.next team
