  • Encroachment Detection - Identification of boundary violations
  • Easement Surveys - Right-of-way and utility easement mapping
  • Mortgage Surveys - Property surveys for lending purposes
  • Fence Line Surveys - Accurate fence and wall positioning
  • Corner Monument Location - Finding and establishing property corners

Applications:

  • Residential property surveys
  • Commercial land development
  • Agricultural land demarcation
  • Industrial site boundaries
  • Government land surveys
  • Legal dispute resolution

Topographic Survey

DGPS Topographic Survey

We conduct comprehensive topographic surveys using DGPS technology to capture detailed terrain information, elevation data, and natural features. Our topographic surveys provide the foundation for engineering design, site planning, and environmental assessment.

Topographic Survey Features:

  • Elevation point collection and contouring
  • Natural feature mapping (rivers, trees, rocks)
  • Man-made feature documentation (buildings, roads, utilities)
  • Cross-section and profile surveys
  • Volume calculations for earthwork
  • Drainage pattern mapping
  • Slope analysis and gradient mapping
  • Site accessibility assessment

Deliverables:

  • Topographic Maps - Detailed contour maps with features
  • Digital Terrain Models - 3D surface representations
  • CAD Drawings - AutoCAD compatible files
  • GIS Data - Spatial database formats
  • Survey Reports - Comprehensive documentation

Control Point Establishment

Our control survey services establish precise reference points that serve as the foundation for all subsequent surveying work. We create networks of accurately positioned control points using DGPS technology, providing reliable reference frameworks for large-scale projects.

Control Survey Services:

  • Primary control network establishment
  • Secondary control point densification
  • Bench mark establishment and recovery
  • Coordinate system transformation
  • Monument installation and documentation
  • Control point maintenance and verification
  • Network adjustment and quality assessment
  • Reference frame documentation

Accuracy Standards:

  • Horizontal accuracy: ±2-5 cm
  • Vertical accuracy: ±3-10 cm
  • Network closure: Better than 1:100,000
  • Multiple coordinate systems support
  • Long-term stability monitoring
  • Professional monument installation
