This session will take up the question of accuracy in drone workflows, including what type of accuracy is needed for which type of job, how to identify when accuracy is good enough for particular requirements, and how to get the most out of drone-based sensors by taking advantage of ground control points. Seasoned practitioners in infrastructure and industry professionals will share brief presentations highlighting real-world examples and best practices from previous work, as well as addressing standards for accuracy as laid out by the ASPRS Positional Accuracy Standards for Digital Geospatial Data. Following the presentations, panelists will return to the stage for a moderated discussion and audience Q&A, where they will address accuracy standards, making decisions about the accuracy of their fleet as it scales, and the challenge of demonstrating accuracy to clients.
How Accurate are Drone Surveys and How to Prove it?
Drones are used more and more in land surveying, but many questions about accuracy remain. Especially in a world where inexperienced users often create bad data with drones, the actual users of drone data are rightly concerned with their accuracy. In this presentation, we will cover exactly how accurate drone surveys can be, how to get there, and most importantly, how to measure and prove it to data users down the line. This presentation will be based heavily on the established academic industry standards for map accuracy: the ASPRS Positional Accuracy Standards for Digital Geospatial Data. The most recent version was released in late 2023 and includes many concepts familiar to drone mapping professionals, as well as new policies and procedures to achieve and certify the best possible accuracy.
