The GISCD team, in collaboration with Sigma Enterprises LLC, conducted an internal survey of the Sewerage Pumping Station in Al Barsha South 3 using the Flyability Indoor Inspection drone and the wearable mobile mapping system from NavVis. These devices enabled the team to perform high-precision survey operations, covering tight and hard-to-reach spaces. This achievement is part of the Digital Twin project, aiming to provide comprehensive information for city planning and management, delivering smart services efficiently.
