User-Friendly, Smart Data Processing Automation for Geodetic Engineers

SurveyCalc is an intelligent AutoCAD extension created for Filipino Geodetic Engineers who want to prepare survey returns faster, with greater accuracy and less manual effort, without changing their drafting workflow.

Fully integrated inside AutoCAD, SurveyCalc converts raw field data and drawings into structured, DENR/LRA-compliant survey returns through a guided and automated system.

From small relocation surveys to large subdivision developments, SurveyCalc helps you validate survey data, generate professional reports, and prepare submission-ready outputs in one continuous workflow.

Draft normally. Process intelligently. Submit confidently.

SurveyCalc unifies drafting, computation, and reporting, reducing errors, saving time, and producing consistently professional survey deliverables.

Platform Capabilities

CAD-Integrated Survey Processing

SurveyCalc works directly within your AutoCAD drawings.

  • Reads and processes existing CAD elements
  • Automatic OCR of LAMS images converted to CAD parcels
  • Automatically generates boundaries, labels, and survey objects
  • Writes computed results back into your drawing
  • Directly imports field data from GPS controllers to PC and back, seamlessly
  • Uses native surveying terminology for a familiar, user-friendly experience
  • Preserves your drafting workflow

Satellite Overlay, DEM Download, and KML Export

SurveyCalc links your drawings to real-world geographic data.

  • Overlay high-resolution satellite imagery on your plans
  • Export KML files for Google Earth visualization
  • Download Digital Elevation Model (DEM) data
  • Use DEM for contouring, slope analysis, and volume computation
  • Automatically capture vector data for vicinity map creation
  • Verify site access, terrain, and surrounding features

Multi-Lot Adjustment Engine

Process multiple adjoining lots as a unified system.

  • Apply Transit or Compass adjustment methods
  • Provide area adjustment for area closure
  • Auto-adjust lots based on smart suggestions
  • Maintain lot relationships automatically
  • Prevent boundary gaps and overlaps
  • Ideal for estate and subdivision layouts

Guided Subdivision Validation

SurveyCalc validates your subdivision before submission.

  • Area difference detection
  • Boundary distance verification
  • Smart corner recognition
  • Automatic lot numbering
  • Prevents accidental modification of computed survey data

Automated Survey Returns Generator

SurveyCalc prepares your complete documentation.

  • Lot Data Computation
  • Field Notes (Cover and Inside Pages)

Automatic Multi-Plan Subdivision Layout

Generate individual lot plan sheets automatically.

  • Insert title blocks, north arrows, and scales
  • Intelligent grid-section layout for multiple sheet generation
  • Maintain uniform plotting standards
  • Batch-ready for printing and PDF compilation
