Topographic Surveys
GNSS RTK Precision at Scale

High-precision land surveys for infrastructure, construction, and planning. 30+ GNSS receivers deployed across Saudi Arabia with ±1–2cm horizontal accuracy.

What We Deliver

Topographic surveys are the foundation of every construction project. Our GNSS RTK network provides real-time, centimeter-level accuracy across any terrain — from urban infill to mountain corridors.

  • ✓ Digital Terrain Models (DTM) with 0.5–1m contour intervals
  • ✓ High-precision land surveys for infrastructure and planning
  • ✓ Road corridor mapping: geometry, right-of-way, utilities, drainage
  • ✓ Cadastral mapping and property boundary delineation
  • ✓ MOMRA-compliant urban neighbourhood surveys
  • ✓ Multiple concurrent crews across Saudi Arabia

Key Capabilities

High-Precision RTK Surveys

GNSS RTK real-time positioning with ±1–2cm horizontal and ±2–3cm vertical accuracy. Immediate stake-out support on-site.

Digital Terrain Models

Full DTM generation with variable contour intervals (0.5m–1m). Slope analysis and volumetric calculations included.

Road Corridor Mapping

Complete geometric surveys: centerline, cross-sections, right-of-way boundaries, utility corridors, drainage flow paths.

Cadastral & Boundary Work

Property boundary surveys, plot subdivision, municipal delineation, MOMRA compliance, Etimad registration support.

Multi-Epoch Campaigns

Repeat surveys for deformation monitoring, settlement tracking, and temporal analysis across large areas.

Integrated GIS Solutions

Seamless CAD and GIS output: AutoCAD DWG, ArcGIS geodatabases, KML/KMZ files, ready for analysis and planning.
