Aerial Survey or drone survey, as it is commonly called, is processing aerial images gathered using drones or unmanned aerial vehicles. These images stitched together with software. The output produces a single high resolution orthomosaic.
Adding high precision GPS or an RTK/PPK solution increases overall accuracy. Surveyed ground control points (GCP's) can be input to rectify the image.
This highly detailed output is accurate regarding global position and elevation. It can be output in local coordinate systems such as Irish Transverse Mercator.
Typical Outputs of Topographical Survey:
- 2D Orthomosaic
- Digital Surface Model / Digital Elevation Model
- Digital Terrain Model
- Contours generated at 0.5m
Aerial Surveying has advantages regarding the speed of delivery compared to traditional methods. It is very cost effective in comparison to traditional surveying. It is not intended to replace but compliment these survey methods.
Using the data captured from drones, engineering surveys have more data points. Whether looking for boundary surveys or land surveying, drone surveying and mapping is the next step..
Inaccessible areas, such as bogs, landfills, quarries are surveyed from the air. It can be difficult or sometimes impossible to get a total station in some of these locations. People and expensive equipment are taken out of harm's way. Aerial surveying has become common in construction. Many other industries can also leverage the same benefits.
Land surveyors are now looking to the skies to assist with there daily tasks. Drones give more detail about man made features.
Quarrying, Waste Management and Environmental protection are dangerous industries. Large machinery and dangerous terrain make it difficult to navigate and more hazardous to survey.
Surveying is very important to these industries. The need to ensure the correct volume is extracted or filled back in. Aerial surveys can solve these issues. Volumetrics, DTMs and DSMs extracted from the data collected from an aerial survey.
Normal operations proceed while the drone is mapping overhead. This reduces site outages or downtime.
All outputs can be in National Grid, or any required coordinate system.
We provide an end-to-end mapping service, from data capture and processing, to output and transfer to our clients.
We use the latest technology in the drone industry to capture acurate, actionable data.
We work with leading software providers in the industry. We produce output in the format you require. These orthomosaics or point-clouds can be imported into CAD or GIS applications.
