TOPOGRAPHIC & QUANTITY SURVEYS
Using drones Polaris can complete very accurate surveys in a fraction of the time of traditional surveying methods. Using the latest software and photogrammetry we can create surveys accurate down to 10-30mm with a ground sample distance of down to 10mm, compared to traditional methods where the output can be in a grid of 5m.
geo-reference points to the data.
From the data collected in our surveys, very accurate measurements and volume calculations can be made.
Using our annotation software we can very accurately measure areas and lengths and volumes. Post build site surveys can be completed quickly and efficiently to show tarmac, paving and landscaped areas. Kerbs, edgings and fences can also be measured.
Surveys like this can be completed with minimum disruption to residents. Aerial surveys remove the need to access properties to make measurements.
Speed and accuracy, this survey was completed and delivered in record time. Traditional methods would require more time to measure out and calculate quantities. Accuracy is very high as all measurements are exact, marking around each area rather than measuring and calculating the areas from a drawing.
STOCKPILE SURVEYS & CALCULATIONS
scramble over stockpiles with a survey staff, and having no need to close operations down as minimal time on the ground is required.
The imagery collected by the UAV is pieced together to create an accurate 3D model so volumes can be almost exactly calculated. This is of huge benefit when calculating stock levels in quarries and other aggregate producers / suppliers. Once the survey has been completed we can easily calculate volumes using the software tools.
Using GCP’s enables us to create a very accurate survey model, down to 10-30mm. This along with a ground sampling distance of between 10-15mm can give much greater accuracy than a traditional staff & grid method.
3D MODELLING & MAPPING
Polaris can accurately model buildings and objects and create a very accurate point cloud. The imagery collated by the UAV is processed using the world’s leading photogrammetry software and a point cloud is created. This 3D point cloud can be ‘explored’ using the online preview software. 3D measurements and volumes (including cut and fill) can be quickly made using the software tools. The data can also be exported in many formats allowing the model to be directly imported into CAD and BIM solutions.
Once the survey has been completed we can easily measure distances,
areas and volumes using the software tools.
ORTHOMOSAIC, ROOF SURVEYS & INSPECTIONS
Aerial photogrammetry can give us an accurate high resolution orthomosaic 2D image. This can provide a useful tool for roof inspections and site measurement. 2D surveys are quicker to collect the data and easier to process than a full 3D survey model.
Using drones Polaris can complete detailed inspections of difficult to access buildings and structures, no need to use scaffolding or high access equipment to inspect structures, we can send a drone up and get close up 4k video and imagery.
UAV’s can be used to inspect difficult or dangerous to access areas. They can also be used on large areas to assess flood or fire damage.
