KEY FEATURES & CALCULATORS
1. AREA & UNIT CONVERSION MATRIX
• Convert land area across regional & standard units:
- Regional Units: Bigha (Pucca/Kutcha), Biswa, Katha, Cent, Guntha, Ground, Marla, Kanal, Gaj (Sq. Yard), Ares.
- Standard Units: Acre, Hectare, Square Feet (sq.ft), Square Meters (sq.m).
• Regional Cadastral State Presets: North India, West Bengal, Assam, Rajasthan, Bihar, and South India.

2. PLOT SHAPE AREA CALCULATORS
• Rectangular Plots: Calculate length × width area and estimated plot value.
• Triangular Plots: Heron's formula surveyor for three-sided irregular plots.
• Irregular Quadrilateral Fields: Calculate four-boundary field area with a diagonal split.
• Trapezoid Plots: Calculate area from parallel sides and height.
• Circular Plots: Instant circular parcel area from measured diameter.

3. GPS LAND SURVEY & KML/GPX EXPORT
• Stand at boundary vertices and capture live GPS pins in perimeter order.
• Instant boundary distance report and total land perimeter calculation.
• Export survey boundaries as KML data (for Google Earth) or GPX files for CAD software.

4. PROPERTY VALUATION & STAMP DUTY ESTIMATOR
• Calculate base land price, government stamp duty %, registration fees %, and total payable quotation.
• Copy and share formatted valuation quotations directly via WhatsApp or email.

5. PARCEL SUBDIVISION
• Subdivide large rectangular land into equal-frontage lots automatically with individual lot area breakdown.

6. FMB / RSR CADASTRAL ADJUSTMENT
• Compare official registered area with resurveyed coordinates to calculate allowable error and variance percentage.

7. CARPET AREA & RERA USABLE SPACE
• Estimate carpet area from super built-up or gross area by accounting for wall allowance and common-area loading.

8. VASTU COMPASS & ORIENTATION TOOL
• Hardware-accelerated live compass dial to determine plot entrance facing direction (East, North, North-East, West, South-East, South, etc.).
• Provides Vastu suitability ratings, element zones (Ishan, Agni, Nairrutya), and direction recommendations.
