Converting LGS (Legacy) to LGSx

Introduction​

Leica's LGS format is considered a legacy file format, previously used for storing and sharing laser scanning data such as 3D point clouds, panoramic images, and measurements. It was designed to work within Leica’s ecosystem, supporting tools like Cyclone and TruView. However, the introduction of the LGSX format marked an evolution in data handling. LGSX is the modern successor, offering improved data compression, faster processing speeds, and better performance for larger datasets. As a result, LGSX is now the preferred format for more efficient workflows, while LGS remains compatible with older systems.

To convert an LGS file to LGSx you have 2 solutions :
