Aerial UAV / Drone Surveys
Aerial Surveys for Marine and Freshwater Ecology
Carcinus Ltd in partnership with Alauda Aerial Surveys Ltd provide a wide range of bespoke aerial survey, remote sensing, mapping and data processing services for freshwater, riparian and coastal environments. Utilising both fixed wing and multi-rotor Unmanned Aerial Vehicle (UAV) platforms, Carcinus and its partners deliver high quality outputs that meet the specific accuracy and scale demanded by each application. All operations are covered under Permission for Commercial Operations (the PfCO), granted by the Civil Aviation Authority (CAA) and are fully insured.
We deliver aerial survey services throughout the UK and abroad and are experienced in undertaking UAV services in challenging environments. Our recent asset inspection surveys undertaken in the Arctic are a prime example of our ability to accommodate client needs when operating in tough conditions.
Matthew Crabb (Carcinus Ltd – Managing Director) is lead author for the JNCC’s latest Marine Monitoring Platform Guidelines on Unmanned Aerial Vehicles (UAVs), published June 2019. The guidelines, provide marine scientists with general guidance on the use of UAV systems for marine monitoring, with a focus on habitat mapping. The guidance also reviews the logistical and operational requirements associated with UAV / aerial surveys for marine monitoring.
The JNCC UAV guidelines are now available to download from the JNCC website – Unmanned Aerial Vehicles for use in marine monitoring
Freshwater and Riparian Aerial Surveys
Through the use of UAV based survey platforms, Carcinus provide an innovative, efficient and diverse range of aerial ecological survey services for freshwater and riparian environments. Our services include:
- Riparian and aquatic habitat mapping and monitoring.
- Salmonid redd counts and fish spawning habitat assessment.
- Structural and asset inspection surveys.
- Topographic surveys for flood risk assessment.
- Aerial surveys to support catchment-based assessments of land use and sediment, nutrient, pesticide and faecal contamination sources.
- Aerial survey input to arboriculture surveys.
- Multispectral imaging for crop / plant health and habitat delineation.
- Photomosaics of fishery beats, lakes or aquatic restoration projects for marketing, engagement and monitoring purposes.
Marine and Coastal Aerial Ecology Surveys
Our UAV service capability offers both a novel and cost-effective means of surveying marine environments not normally accessible or too extensive to safely and efficiently survey by traditional means. We provide the following cutting edge marine aerial survey services:
- Enhanced Phase I (and extended Phase I) habitat surveys, enabling efficient survey of wider / harder to reach areas.
- Monitoring of unlicensed activities such as bait digging, crab tilling and shellfish harvesting.
- Monitoring coastal change, erosion and accretion.
- Habitat extent monitoring, using cost effective and highly repeatable survey methodologies to enable monitoring over any temporal scale.
- Macro-algae and saltmarsh extent and health monitoring by an unobtrusive and non-destructive means of surveying, including multispectral imaging and analysis.
- Wildlife monitoring via aerial image and video acquisition.
Aerial Asset Inspections Surveys
Our aerial surveyors are experienced in the aquaisition of aerial still and video imagery for the asset inspection purposes. Having delivered these services within the UK and in challenging environments, including the Arctic, we are well placed to meet our clients’ needs. We operate UAV survey service in both terrestrial and marine environments and can survey a wide range of infrastructure. Our aerial asset inspection services include:
- Acquisition of still imagery for Structure for Motion (SfM) and photogrammetry processing.
- High resolution videography and post processing.
- Post processing including:
- Coloured point clouds
- Textured mesh models
- Digital surface models
Outputs and Deliverables
All outputs are designed to meet our clients’ needs, ensuring the accuracy and scale are targeted to the specific requirements of the project and meets regulatory requirements. Outputs typically comprise:
- 2D photogrammetry and photomosaics.
- Point clouds, mesh, 3D models and BIM level modelling.
- Digital surface and terrain models (DTM & DSM).
- Multispectral analysis and indices.
- Habitat maps.
- High resolution digital still imagery and video.
- 3D modelling processed into Virtual Reality experience.
