LGO is a comprehensive office software suite for surveying and GIS professionals. It handles everything from raw GNSS data processing and traverse adjustment to COGO (Coordinate Geometry), terrain modeling, and data transfer between the office and field controllers (like the Leica Viva or CS series).
It represents the peak of the "classic" Leica processing philosophy: reliable, deterministic, and fast. While Infinity is superior for CAD integration and point cloud handling, LGO 8.3 remains the go-to solution for surveyors who prioritize rock-solid GNSS baseline processing and total station data management.
What makes for power users is the Visual Basic for Applications (VBA) editor. You can script custom exports to match specific client CAD layering standards or generate unique stakeout reports that generic software cannot produce.
