Ensuring Data Accuracy from Drone Surveys

Accuracy is the number one priority in drone surveying, so it is essential to ensure that the data collected from a drone survey mission is properly calibrated and validated before use in analysis or decision-making processes. Multirotor drones are the most commonly used drones for civil construction, mining, aggregates and waste management companies. To verify and fix drone images to the ground, a sufficient number of known points are needed. Therefore, it is important to choose a drone surveying software that integrates with existing workflows and makes daily workflow easier.

Propeller recommends using PPK instead of RTK to perform drone inspections anywhere. Drones are cheaper and easier to use than traditional surveying equipment, so there is no need to spend a lot of money on hardware or have special training or education to capture site data. Survey data captured by drones and processed by software platforms such as Propeller helps to centralize project documentation and increase collaboration with surveyors, engineers, foremen and site managers. Keith Taylor manages the GPS machine control equipment, site positioning, manual topography instrumentation and drone topography, which he does through the Propeller PPK workflow.

Drone topography offers a number of benefits for the mining and aggregates industries, including improving efficiency, using mine exploration and inspection, and improving safety standards. Drone topography allows site supervisors and superintendents to receive updated maps with precise specifications approximately one day after requesting them, contributing to better decision-making and, ultimately, reducing work. Before a mining operation begins, a drone can survey the site to explore how much mineral potential exists. However, a drone reconnaissance flight can be performed from a safe position on site without exposing workers to hazardous areas.

In addition, with the right processing platform, such as Propeller, you can get the data you need from every drone flight and ensure that you are compensated for the work you do, thus obtaining a significant return on your investment in a drone program.
