2. Terrain

Flat terrain (no DEM download)

Import custom DEM (max 3x3 km, projected GeoTIFF)

Click on the map to select terrain center, or draw rectangle.

3. Single structures (optional)

Place individual structures

4. Structure grid (optional)

Place a regular grid of structures

5. Sampling points (optional)

Add sampling point(s)

6. Predict

Model

Final hybrid cascade trained on the full 292-domain split with y-reflection augmentation and physics losses. Best aggregate accuracy and fastest inference; smoother between closely spaced grid structures than the 3D UNet.

Uncertainty map (runs both model families, ≈2× time) Wind rose (multi-direction sweep)

If you placed structures, click Confirm structure(s) first. Otherwise, Predict will build inputs automatically.

Ready. Click on the map to select terrain.
