Digital 3D modelling of LRI, GH & LGH

Tender description

Murphy Geospatial (MGS) will provide an aerial survey using an Unmanned Aerial Vehicle (Drone). Both LIDAR and Photogrammetric datat will be captured. The processed data will comprise of the collection of overlapping photos to enable photogrammetric principles to be used to create the desired outputs. The expected horizontal accuracy will be +/-50mm (position) for hard detail such as buildings and walls and +/75mm (position) for soft detail such as vegetation and surface changes. Vertical accuracy (levels) will be to +/75mm for hard detail and +/- 100mm accuracy for soft detail. The survey will be based on the installed survey control and will relate to the Ordnance Survey Grid and Newlyn Datum. No complementary scans will be captured on the ground. The service was market-tested across a total of five suppliers, but a non-standard output is required and two-way engagement was required so that the solution could be led by sup ## Contract award
