DRONES FOR Environmental inspection and ASSESSMENTS
When it comes to shaping the environment around us, drones can save professional contractors time, labour, and money. Whether it’s landscape creation, golf course maintenance, or sports field management, drones offer a number of advantages over traditional environmental management methods.
When it comes to assessing and monitoring the environment, drones are the perfect tool for surveying, conceptualising, and reporting on current and potential conditions and designs.
This process involves the use of both visible and near-infrared bands of the electromagnetic spectrum to collect and analyse data, assessing whether the target area contains healthy vegetation.
Crop analysis, chlorophyll level determination, plant health and stress level determination, optimal fertilizer use, nitrogen management, insect and pest in crop identification, plant disease analysis, plant or weed identification.
The accurate and efficient data capture capabilities of drones provide the latest and accurate information required to support environmental impact assessments.
Aerial data for environmental assessments, data for erosion and scour investigations, aerial data for GIS applications, geo-referenced high-resolution ortho-rectified imagery up to 1 cm GSD, high-resolution Google Earth overlays.
Using photogrammetry (a surveying and mapping technique), drones provide quick deployment and turn-around times with accurate reporting from point cloud datasets. Survey ground control, processing, and reporting tasks are carried out by our experienced and registered surveyors.
Uneven terrain can cause difficult and hazard working conditions for surveyors travelling over land on foot. Drones are able to quickly and precisely retrieve topographical maps of large areas with minimal wear and tear on equipment and low risk.
Predesign surveys for site planning, detailed surveys of existing infrastructure and topography, Digital Surface Models (DSM) and Digital Terrain Models (DTM), contour maps, accurate geo-referenced ortho-rectified imagery and maps, geo-referenced high-resolution orthophotos up to 1cm GSD.
The HydroLite-MB Multi-beam is a portable, bathymetric, dual frequency survey system. It has been designed as a turnkey, shallow water multi-beam rig, pre-installed and pre-calibrated on its mounting frame, useful in aquatic surveying.
Shallow water multi-beam surveys, depth sounding (sound velocity profiler), ultra-high resolution sonar, side scan imagery, identification of critical and dangerous objects on the harbour bed.
An automatic bathymetric drone catamaran capable of providing aquatic surveying.
Monitoring of various marine sites, generation of Sub-surface Digital Terrain Models (DTM).
LiDAR (Light Detection and Ranging) is a remote sensing method that uses light in the form of a pulsed laser to measure ranges to objects. These light pulses - combined with other data – can be used to generate precise, three-dimensional information.
Airborne LiDAR survey involves the use of a LIDAR sensor to rapidly scan the environment using Laser and GPS technology, saving on time and costs.
Topographic surveys, accurate Digital Terrain Models (DTM) and Digital Surface Models (DSM) in areas with vegetation, engineering design surveys, corridor / strip surveys, slope monitoring, as-built surveys of existing infrastructure and architecture, accurate ortho-rectified imagery.
Terrestrial LiDAR (3D laser scanning) technologies provide 3D survey data that are accurate, dense and more economically produced than data from surveys using traditional techniques. This can be extremely useful in the documentation of structures such as oil and chemical refineries, highways, bridges and other complex structures, producing accurate ‘as-built’ drawings in very little time and with very little expense compared to traditional methods.
