The Unlikely Surveyor with Rami Tamimi

Using Consumer-Grade Sensors for High-Accuracy Mobile Mapping: Teslas, Smartphones & GNSS | Full Talk

In this presentation, Rami Tamimi professional surveyor and Founder of the Survey School – shows how consumer-grade hardware can be turned into high-accuracy mobile mapping systems.

From UAVs and smartphones to Tesla dash cams paired with RTK GNSS, Rami walks through his research on camera calibration, GNSS synchronization and photogrammetric workflows that extract survey-grade data from affordable, off-the-shelf devices. He also demonstrates his own software platform SurveyXR (GeoFrame), built to make this kind of experimentation and research more accessible to surveyors and geospatial professionals.

About INTERGEO:
📌 INTERGEO EXPO and CONFERENCE is the international platform for geodesy, geoinformation, and land management. It takes place at changing locations throughout Germany. The CONFERENCE addresses current topics from politics, administration, science, and industry. With its geo-IT potential, INTERGEO continues to focus on optimizing processes in growing target markets. It was held in Frankfurt am Main in 2025. In 2026, it will be hosted in Munich, and from 2027 onwards it will be held permanently in Frankfurt am Main. The organizer of INTERGEO is DVW e.V. – Society for Geodesy, Geoinformation and Land Management.
