Gaussian Heatmap

CSV columns: latitude longitude value.

Data file (.csv)

The map auto-fits to your data. Typical size ≤ 500 rows.

Radius σ (meters)

30 m — Gaussian radius.

Neutral value λ

We render with v′ = value − 1.0.

Normalization

Opacity

We render with opacity = 0.85.

Fade radius

Transparent near neutral ±0.10.

Fade softness

0 = hard edge, 1 = smooth fade (1.00).
