Topographic Survey

Topographic surveys are undertaken to obtain elevations of terrestrial and intertidal areas as well as to identify assets and features. We use a range of topographic survey techniques depending on the nature of individual sites and client requirements.

We conduct topographic surveys using both traditional Total Station techniques and with Global Navigation Satellite Systems receivers, using real-time kinematic (RTK) corrections.

For high-resolution elevation datasets over a wide area, we offer UAV (unmanned aerial vehicle) surveys using drones fitted with the latest survey sensors.

Cross-sectional profiling: We collect cross-sectional profiles over terrestrial and intertidal areas. Surveys can be conducted either on a singular basis (to produce immediate elevations), or over multiple periods to build a history of change over a defined area.

Extent mapping: We survey spatial extents of transitional areas within terrestrial and intertidal zones such as saltmarsh, reedbed and mudflat. Like cross-sectional profiling, this can be conducted on singular or multiple time frames depending on requirements.

Ground truthing: We conduct a combination of single-point observations and cross-sectional profiles to verify existing elevation datasets such as Light Detection and Ranging (LiDAR) or single-beam/multi-beam bathymetry.

UAV services: We provide bespoke UAV surveys using un-manned aerial vehicles. Drones are fitted with high-resolution RTK enabled survey sensors to map large areas of interest. UAVs have the unique ability to survey areas in which conventional topographic methods cannot be safely or practically conducted.
