2) Topographic Surveys
Topographic Surveys to specification from client based on needs and requirements of survey. Costing based on survey specification and nature of site.
All relevant data captured using a mixture of rtk GPS and Total Station related back to control points.
3) Drainage Network Surveys
As part of Topographic Survey (where required) a drainage network survey including cover level, invert and route can be surveyed.
Where network is in main carriageway Traffic Management can be supplied.
4) Measured Building Surveys
Laser Scanner to be used to carry out Measured Building Surveys. Scans to be related to control points in ITM OSGM15, installed using GPS/Total Station combination.

Aerial Survey to be carried out to capture roof detail not captured by laser scanner.
Survey can be outputted as a PointCloud .las file, .rcp Autodesk pointcloud, .jpg or as a PDF
5) 2D and 3D Aerial Pointclouds
Aerial Surveys using a UAV quadcopter up to an area of 10 Hectares typically.
Aerial Survey related to Ground Control Points installed using RTK GPS.
Outputs from an aerial survey include:
– 2D .tiff image which is scaled, orientated and to grid coordinates when imported into an AutoCAD drawing, providing context to the overlayed survey.
– 3D pointcloud of area in .las format.
6) Hydrology Surveys
Depending on nature of waterway/time of year, Hydrology surveys carried out using suitable combination of Orange Safety Boat, Canadian Canoe or waders.
