Porosity analyzer.
Upload a batch of side-on photographs of a windbreak. The instrument computes optical porosity per photo and a filtered batch average suitable for reporting.
Step 01Drop in your photographs
Step 02Calibrate the cutoff
Drag the top edge of the band on the photo to choose what gets ignored. Use this for ground, fences, or anything at the foot of the windbreak. The same cutoff is applied to every photograph in the batch — the preview just shows your first one.
Step 03Analyze the batch

Estimated wind impact
Estimate based on published wind-tunnel and field studies (Cornelis & Gabriels, Heisler & DeWalle, Brandle et al.). Treat as an indicative range, not a precise forecast — actual reduction depends on wind speed, atmospheric stability, and 3D shelterbelt structure that one porosity figure cannot fully capture.
Weak spots detected
Sections of your windbreaks that are too dense (low porosity, causing turbulence) or too open (high porosity, insufficient wind reduction). Optimal range is 20–50%.

How the instrument sees each photograph
White = sky/gap, black = vegetation. If this looks wrong, the porosity figure cannot be trusted.
