There are now many platforms that provide centimetric accuracy based on Real-Time and/or Post-Processed Differential Positioning Solutions. We have surveyors review the positioning solutions so that you get deliverables ready for your engineers to use. LiDAR and/or Optical-based mapping solutions are used depending on the nature of your terrain and budget.
While Near Infrared electromagnetic radiation is useful for vegetation health mapping, the thermal infrared, as observed through the so-called thermographic cameras, is useful for thermal inspections; for example: building thermal efficiency; solar panel condition.
Network Operatiors have used Drones for cell phone tower inspections and feasibility studies for a long time. Highly detailed photography and 3D models of the Towers are used by inspectors to map the tower occupancy and the state of its components.
Specific photogrammetry algorithms, and also LiDAR sensors and georeferencing solutions have been developed for lightweight Drone platforms. Models with resolution < 10 cm and centimetric accuracy are increasingly used for volumetric and earthworks purposes. Topographic models from photogrammetric algorithms won't properly reveal bare-ground in highly vegetated areas. Several lightweight LiDAR sensors are available for Drones.
Crop Health & Vegetation
Multispectral Sensors onboard drones capture information inaccessible to the unaided human eye. This information reveals crop and vegetation conditions such as hydric stress and biomass. That kind of information is useful, for instance, to determine irrigation spatial and temporal patterns.
Construction Site Mapping
Drone Survey-Grade Orthophoto Maps and 3D models are quick to produce and provide engineers with detailed and actionable information that would take much longer to determine from the ground. We can use your ground control to get a tight match between the aerial data and the construction site spatial reference system.
Large Engineering Projects can benefit from repeat video and photo that shows project temporal evolution to project managers both onsite and offsite. Examples include linear features such as pipelines. Generally speaking, regular Drones, under the standard legislative constraints or Air Traffic Regulators, have the capacity to Image 50+ linear km in one day.
Orthophoto Maps (aerial imagery) from Drones reveal forest stand details that are not possible to realize from the ground or satellite imagery. During cutblock layout, those orthophotos help determining areas of interest, and thus also optimize field resource allocation. Post-harvest, orthophotos reveal the scope of the activities, and how they compare to the permitted scope.
4k Videography & Photography
Aerial Footage from Drones is today Ubiquituous, from newscasts to tv shows. Filming crews do not always have the gear and licensing required to perform such shoots, and thus rely on contractors.
