Higher is better. 100 = fully aligned with traditional Vastu principles; 0 = inauspicious on every axis. Three geometric signals combine into the total:

Facing direction  — 40 points

Bearing from the home toward the nearest road (the direction your front entrance faces). Vastu favors entrances that catch morning light and the "Ishanya" (NE) energy corner.

Site slope  — 30 points

Elevation sampled at four corners of a 60m box around the property. Vastu prefers land that rises toward the SW (so the NE corner is lower) — symbolically draining negative energy away from the auspicious NE.

Plot shape  — 30 points

Derived from the TCAD parcel polygon. Three sub-signals, summed:

• Aspect ratio (0–12 pts) — width / height of the north-aligned bounding box. Square-ish (1.0–1.5) is best; slivers (>3.0) score 0.
• Convexity (0–10 pts) — polygon area ÷ convex-hull area. 1.0 = convex (ideal); L-shaped or pinched lots score lower. Vastu strongly prefers regular shapes.
• Cardinal alignment (0–8 pts) — how far (degrees) the longest edge is from N/S/E/W. Lots aligned with compass directions score higher.

What's missing: kitchen position, master bedroom, prayer/pooja room, exact door placement, interior colors, water features — all require a floorplan or site visit. A strict Vastu reading would include these; this score is directional only.
