Notes on methods
Uniform in BBox: fast. Use when AOI is a rectangle.
Uniform in Polygon: fair coverage. Good for simple AOIs.
Stratified + Jitter: lower clumping. Use when you need more even spread.
Poisson Disk: blue‑noise. Good for sampling without neighbors too close.
Hex Lattice: regular grid. Good for transects and field teams.
