Drone Mapping Accuracies and limitations using ultra high resolution camera systems
Building on camera accuracy testing performed on DJI X4S camera systems, follow up research was performed on the Phase One iXM-100 camera system. This presentation will demonstrate the achievable accuracy of that camera system and some of the limitations discovered using conventional survey techniques for verification of the data.
Common Errors in Survey-grade Mapping Workflows
Achieving survey-grade mapping data can be difficult, and at times, seem impossible with sUAS platforms. We will discuss common pitfalls in the UAV surveying workflow and how to avoid them. Your initial survey configuration, ground control layout, and post-processing options all have an impact on your final accuracies and we’ll walk you through some of the common (and not so common) errors along the way.
Flood Forecasting and Model Verification: Exploiting a Group 3 UAS
In spring 2019, National Weather Service (NWS) Lower Mississippi River Forecast Center (LMRFC) continued its research collaboration with NOAA’s Northern Gulf Institute and Mississippi State University to demonstrate UAS and computer processing capabilities to provide near-real time visible imagery, NIR imagery, and derived products to LMRFC during flood events. We will present outcomes from the April 2019 flight operation that occurred during the historic 2018-2019 Mississippi River flood event. We will discuss the equipment, data collection and data dissemination process for 15cm resolution imagery collected in 6 flight hours over 300 square miles and the value of this data to LMRFC’s river forecast operations.
