Detailed topographical surveys are captured using robotic total stations in combination with the capture of field observations by a surveyor with a detail pole and prism reflector. Data is observed in the field in point code and string-line forms which allow the direct export and manipulation of digital ground model features in bespoke survey software solutions (LSS) . Such 3d DTM data is then exported in a high quality AutoCAD 2d cartographical form for planning and interpretation use together with a 3d stringline and surface triangle mesh for use with 3d systems such as Revit.
All topographical survey data capture techniques utilise the very latest technology including Leica & Trimble GNSS receivers which are linked to the Ordnance Survey active network, terrestrial laser scanning techniques via a Trimble SX10 & Leica P40 3d data capture and also the use of SfM Aerial Photogrammetry via various UAV platforms flown by fully qualified and CCA approved pilots.
