Trimble SiteVision is an augmented reality (AR) positioning system designed for visualizing geospatial and construction data directly on site. The system combines GNSS positioning technology with augmented reality visualization, allowing users to view digital design models, underground utilities, and project data in their real-world environment using a mobile device. SiteVision connects field teams with digital project data, enabling accurate visualization of BIM models, CAD drawings, utilities, and infrastructure layouts directly on construction sites. This improves communication between engineers, surveyors, contractors, and stakeholders while helping reduce errors during project execution. The system is widely used for construction planning, site inspections, infrastructure projects, GIS visualization, and utility mapping. By overlaying digital information onto the real environment, Trimble SiteVision helps teams make better decisions in the field. Through the Topotronix platform, professionals can access innovative geospatial solutions like Trimble SiteVision, enabling advanced visualization workflows for construction, surveying, and infrastructure projects.
