Twozan Surveys provides high-accuracy topographic surveying and mapping services across Saudi Arabia, capturing existing ground conditions, elevations, contours, natural features, structures, roads, and utilities. Using advanced GNSS/GPS systems, robotic total stations, mobile mapping, and 3D laser-scanning technology, we deliver reliable contour maps, digital terrain models, cross-sections, CAD drawings, GIS data, and earthwork volume calculations. Our topographic surveys support urban and regional planning, infrastructure design, road and utility-route development, site preparation, grading, construction, and quantity estimation. Every survey is tailored to the required scale, format, and project specifications—providing engineers, architects, contractors, and developers with precise geospatial data for smarter planning, efficient design, and successful project execution.

Topographic Survey – Twozan Surveys 

Topographic data collection is performed using conventional total stations, GNSS RTK satellite-positioning systems, or an integrated combination of both. The most suitable method is selected according to the required accuracy, level of detail, terrain conditions, satellite visibility, site accessibility, and project schedule. These technologies produce compatible coordinate and elevation data, enabling efficient and reliable mapping across projects of varying size and complexity.

At Twozan Surveys, we understand that accurate and complete topographic data is fundamental to successful engineering design, planning, and construction. Our structured workflow includes clear project-scope definition, survey-control establishment, professionally supervised field data collection, advanced data processing, and rigorous quality assurance and quality control. Every coordinate, elevation, contour, feature, drawing, and digital model is carefully verified against project specifications and recognized professional standards.

Twozan Surveys has successfully completed numerous topographic mapping projects across Saudi Arabia for infrastructure, construction, urban development, road and utility-route design, site grading, and engineering-planning applications—delivering dependable geospatial information that supports confident decisions and successful project execution.
