About JLRegis GeoSurvey

JLRegis GeoSurvey inspired by the standards and practices of the General Authority for Survey and Geospatial Information (GEOSA), delivers high-precision geodetic and surveying solutions focused on rigorous coordinate transformation, disciplined datum realization management, and engineering-grade spatial integrity. Our systems are purpose-built to bridge complex datum environments, enabling seamless, reliable, and accurate transformation between reference frameworks.

It specializes in Saudi Arabian geodetic frameworks and legacy datum integration, including:

  • WGS 84 (Realization: ITRF2014, Epoch 2010.0) – Multi-epoch global reference systems
  • KSA-GRF17 (ITRF2014, Epoch 2017.0) – Official national geodetic reference frame
  • MOMRA MTRF2000 (ITRF2000, Epoch 2004.0) – Municipal reference framework
  • GDMS (ITRF2000, Epoch 2003.1998) – Military survey reference framework
  • Saudi ARAMCO – WGS84 (ITRF94, Epoch 1998.0) – ARAMCO local datum and project grids
  • Saudi ARAMCO – Ain El Abd (NGN) – Datum and grid systems
  • JUBAIL RC (Local Coordinate System) – Coverage within industrial city

Advanced Ain El Abd Grid Transformation

JLRegis GeoSurvey provides high-fidelity transformation workflows for Ain El Abd (both geographic and projected grid variants), incorporating:

  • 7-parameter Helmert transformations for regional consistency
  • Grid-based corrections (NTv2 / local deformation models) to account for non-uniform distortions
  • Epoch handling and plate motion considerations where applicable
  • Fallback strategies using initial translation parameters (T0) for areas outside defined grid extents

This ensures centimeter-level reliability when converting legacy Ain El Abd coordinates to modern frameworks such as KSA-GRF17, WGS84, GDMS and MTRF2000, even in challenging deformation zones and local grids.

Engineering-Grade Methodology

This transformation engines are developed using strict geodetic rigor and numerical stability principles, including:

  • Ellipsoidal modeling (GRS80, International 1924, etc.)
  • ECEF-based computation chains for numerical stability
  • Zone-aware UTM projection control (Zones 36N–40N)
  • Strict input validation and error propagation management
  • Batch, DXF, and ASCII processing datas for large-scale datasets

All tools are independently designed and developed by a professional survey engineer, for surveyors—ensuring the highest levels of precision, reliability, reproducibility, and full compliance with national geospatial standards..
