Special Issue Information
Dear Colleagues,
This Special Issue will focus on exploring the great potential of accurate GNSS positioning for UAV remote sensing provided by on-board RTK-capable GNSS receivers. Fixed-wing as well as multirotor UAVs equipped with such technology are now available at affordable prices. White papers from manufacturers and a number of papers on experimental tests suggest consistent and accurate results can be expected of such systems, with important consequences on project feasibility and costs. Though not all UAV applications in remote sensing need cm-level georeferencing accuracy, many do, and many others may benefit from this technology, opening up new possibilities, especially in multitemporal analysis and monitoring, whenever providing and/or maintaining ground control points over time can be difficult.
Contributions to this Special Issue of Remote Sensing are welcome on every aspect of UAV remote sensing benefiting from GNSS RTK-assisted sensor positioning, from data acquisition to data processing and restitution. Methodological contributions are especially encouraged on sensor orientation methods, bundle block adjustment best practices, and multispectral image orientation. Application-oriented papers are also welcome, with case studies emphasizing where RTK positioning brings real improvements compared to current state-of-art or opens the ground to new applications.
Topics of interest include but are not limited to the following:
- Block design and block imaging geometry with RTK camera positioning; critical imaging geometry configurations for RTK-assisted image orientation;
- High precision navigation. Planning for pinpoint imaging;
- Sensor positioning: GNSS data processing; RTK (real-time kinematic) versus PPK (postprocessing kinematic); network RTK versus single-station RTK; IMU/GNSS integration;
- Image orientation: techniques and requirements for camera calibration and/or lever arm calibration; camera position data integration with ground control; weighting of image and camera observations in bundle adjustment, including GNSS data stochastic modeling;
- Data processing and applications: accuracy of georeferencing (points, DTM, orthoimages) of multitemporal surveys and its consequences on multitemporal analysis in any application field; case studies on benefits and limitations of RTK positioning for new applications and for project feasibility (costs and frequency of multitemporal surveys); benefits on synchronous and asynchronous (multitemporal) image registration techniques of single or heterogeneous bands (multispectral, thermal, RGB); benefits for autonomous navigation and obstacle sense and avoidance.
