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.

Floor plan  — +40 points (Tier B)

When a floorplan PDF is available, Gemini vision extracts cardinal-direction placements for six key features. Each feature awards bonus points based on traditional Vastu ideals; the floorplan score adds on top of the base (facing + slope + shape), raising the max to 140.

Penalties: toilets in NE or SW are marked -3; pooja in S or SW gets -3. Ranges sum to ~±40.
