Professional Surveyor: Land, Boundary & Civil GNSS Survey Suite

Mainstream surveying field controllers and CAD data collectors (Carlson SurvPC, Trimble Access, FieldGenius) cost $150–$600/year in recurring software licenses, require bulky specialized hardware, and lock point data behind proprietary cloud vaults. Civil engineers, land surveyors, fencing contractors, timber cruisers, farmers, and property buyers need an instant on-the-spot Android tool to calculate closed boundary traverses, parcel acreage, benchmark stakeouts, COGO coordinate geometry, and multi-point GNSS observation averaging 100% offline. Core Features: • Multi-Point GNSS Observation Averaging: Filter multipath error with 10s to 300s continuous fix logging and live Standard Deviation (σ_lat, σ_lon, σ_elev) indicators • Boundary Traverse & Closed Acreage Engine: Traverse sequential benchmarks to compute exact enclosed boundary area in Acres, Sq Ft, Hectares, and Sq Meters • Survey Chains & Perimeter Measure: Instant boundary perimeter in Surveying Gunter's Chains (66 ft), Rods (16.5 ft), Feet, and Meters • COGO (Coordinate Geometry) Inverse: Enter any two survey pins to compute exact geodetic azimuth/bearing (e.g. N 45° 12' 30" E), horizontal ground distance, slope distance, and elevation delta (ΔZ) • COGO Forward Point Projection: Project new boundary corner coordinates from any known benchmark using target bearing and distance • Benchmark Stakeout & Cut/Fill Guidance: Real-time compass navigation and rangefinder steering to target design pins with live Cut/Fill elevation delta • Civil Slope & Earthwork Grade: Percentage grade (%), slope ratio (e.g. 4:1, 3:1), and ditch leveling • Standard Survey Data Export: 1-Tap export to industry-standard PNEZD CSV (Point#, Northing, Easting, Zenith, Description), LandXML, and DXF • 100% Offline & Sovereign: Zero cloud subscriptions, zero ads, zero tracking, zero internet connection required 100% Offline • 75% Less Than Mainstream Subscriptions • Zero Cloud Accounts Required.
