Composite Vastu score
Sum of independent factors below. Higher = more aligned with traditional Vastu Shastra principles.
Tier A (location-derived) max 100. No floorplan analyzed for this property.
Last scored May 26, 2026. Inputs: lat/lng (30.32671, -97.77563), TCAD parcel pID 123420.
Factor 01 · Tier A
Facing direction 40 / 40
Bearing from property to nearest road point: 34.0°
Cardinal bucket: NE (45° sector centered on each compass point)
Nearest road: Spinnaker Cove
What it measures: the cardinal direction the home's primary entrance faces. Vastu treats N / E / NE entrances as most auspicious — they catch morning light and the rising sun, both associated with prosperity.
Data source: OpenStreetMap Overpass API — queries every road (any
highway=* tag) within an
80 m radius of the property's lat/lng. The bearing from the property toward the closest point on the closest road is treated as the facing direction. The map above plots the property pin and the parcel outline on the same CARTO Positron tiles used elsewhere in this site; the red arrow points along the computed bearing.
Scoring table:
| Facing | Points | Why |
|---|
| N | 40 | Catches midday sun, classic auspicious orientation |
| E | 40 | Sunrise-facing — most auspicious entrance per Brihat Samhita |
| NE | 40 | Ishanya corner, associated with the divine |
| NW | 30 | Vayu corner, mild but acceptable |
| W | 22 | Neutral; afternoon glare |
| SE | 20 | Agni corner — fire energy, OK for kitchen, weak for entrance |
| S | 12 | Yama direction; heat-loaded south face |
| SW | 0 | Nairutya corner — most inauspicious entrance |
Result:
Front faces NE → 40 / 40.
Factor 02 · Tier A
Site slope 8 / 30
Highest corner: SE · Lowest: NW
Range across the 60 m sample box: 1.56 m (5.1 ft)
SW − NE diagonal: -1.4 m → NE_higher (inauspicious)
Property location with the parcel outline (green) and the 60 m × 60 m sample box (dashed) used for the four USGS elevation queries above.
What it measures: the ground-level drop or rise from the NE corner to the SW corner. Vastu prefers a site that rises toward the SW (heavier southwest, lighter northeast) — believed to anchor stability while letting morning energy flow in from the NE.
Data source: USGS Elevation Point Query Service — free 1-arc-second DEM (≈10 m horizontal, <1 m vertical RMSE in flat terrain). Sampled at 4 corners of a 60 m × 60 m box centered on the
TCAD parcel centroid (not the geocoded address point, which on large lots can sit on the road or a neighboring parcel and bias the slope sample).
Scoring table:
| SW − NE (m) | Interpretation | Points |
|---|
| ≥ +0.5 | SW higher than NE (ideal) | 30 |
| −0.5 to +0.5 | Effectively flat | 18 |
| −2.0 to −0.5 | NE moderately higher (suboptimal) | 8 |
| ≤ −2.0 | NE much higher (inauspicious) | 0 |
Result:
SW − NE diagonal = -1.4 m → 8 / 30 (NE_higher (inauspicious)).
Factor 03 · Tier A
Plot shape 26 / 30
Left: parcel polygon shape from TCAD (north up). Right: same polygon overlaid on CARTO street tiles for geographic context.
What it measures: three properties of the parcel polygon — how rectangular (aspect ratio), how regular (convexity), and how aligned with N/S/E/W axes (cardinal offset). Square, convex, cardinally-aligned plots score highest.
Scoring (sum of three sub-rules, max 30):
| Aspect ratio · max 12 |
|---|
| 1.0 – 1.5 | 12 |
| 1.5 – 2.0 | 8 |
| 2.0 – 3.0 | 4 |
| > 3.0 | 0 |
| Convexity · max 10 |
|---|
| ≥ 0.95 | 10 |
| 0.85–0.95 | 6 |
| 0.75–0.85 | 3 |
| < 0.75 | 0 |
| Cardinal offset · max 8 |
|---|
| 0° – 10° | 8 |
| 10° – 25° | 4 |
| > 25° | 0 |
Result:
Square parcel, aspect 1.14, convexity 0.976, 22.3° off-axis → 26 / 30.
