Trimble Access Coordinate System Database

Trimble Access Coordinate System Database, developed by Trimble Inc., is the geodetic backbone of Trimble Access field software. It provides a curated library of global and regional datums, ellipsoids, map projections, and vertical reference frames, along with the transformations and geoid models needed to achieve accurate positions. By offering authoritative definitions and both parameter-based and grid-based transformation methods, it enables surveyors to set up jobs correctly, convert between GNSS coordinates and local control, and deliver precise horizontal and vertical results.

Designed for field reliability, the database works offline on Trimble controllers and tablets and supports GNSS, total station, and integrated survey workflows, ensuring consistent results across crews and devices. Regular updates from Trimble keep the content aligned with current national and industry standards, reducing setup time and the risk of transformation errors. Ideal for land surveying, construction, and engineering projects, it helps teams meet specifications and maintain accuracy wherever they work.
