Zone coverage summaries
[zone,total cells,valid cells,valid area,valid fraction,valid mean or no data]; invalid masks excluded from statistics.
Symbols and units
- a
- Raster cells [zone ID,value,valid mask 0/1]
- b
- Cell area (m²)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Raster masks, zone cells, missing-data policy. Returns Valid coverage and zone summaries. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Cell area (m²): minimum 1e-12, maximum 1000000000000.0.
