Special Issue Information

Dear Colleagues,

With the increase in earth-observing satellites, the volume of timely remote sensing data at large scales is rapidly growing. It is a challenge to mine the potential information in massive remote sensing data automatically and accurately. In the past few years, artificial intelligence technology, especially deep learning, has achieved great success in the automatic recognition, classification, and extraction of images and videos; it can fulfil the needs of remote sensing images. Although much architecture with an outstanding performance has been proposed in the last few years to address RS problems, there is much room for improvement.

This Special Issue aims to collect the latest developments and applications of both basic and applied research on deep learning applied in remote sensing, with particular attention to the structure and performance of deep learning models suited to remote sensing data, and the mining of potential natural rules in remote sensing data. Research can focus on, but is not limited to, landscape- or green-areas-related image fusion, image registration, scene classification, object detection, LULC classification, image segmentation, object-based image analysis (OBIA), and so on. The application research of artificial intelligence methods such as machine learning/deep learning and remote sensing technologies such as optical remote sensing, LiDAR, UAV, and InSAR are particularly welcome. Original research articles and reviews are welcome.

I/We look forward to receiving your contributions.

Agricultural terraces are important artificial landforms on the Loess Plateau of China and have many ecosystem services (e.g., agricultural production, soil and water conservation). Due to the loss of rural labor, a large number of agricultural terraces have been abandoned and then the degradation of terraces, caused by rainstorm and lack of management, threatens the sustainability of ecological services on terraces. Our previous study has found its geomorphological evidence (sinkhole and collapse). However, no quantitative indicators of terrace degradation are identified from the perspective of microtopography change. A framework for quantifying terrace degradation was established in this study based on unmanned aerial vehicle photogrammetry and digital topographic analysis. The Pujiawa terraces in the Loess Plateau were selected as study areas. Firstly, the terrace ridges were extracted by a Canny edge detector based on high-resolution digital elevation model (DEM) data. The adaptive method was used to calculate the low and high thresholds automatically. This method ensures the low complexity and high-edge continuity and accuracy of the Canny edge detector, which is superior to the manual setting and maximum inter-class variance (Otsu) method. Secondly, the DEMs of the terrace slope before degradation were rebuilt through the terrain analysis method based on the extracted terrace ridges and current DEM data. Finally, the degradation of terraces was quantified by the index series in the line, surface and volume aspects, which are the damage degrees of the terrace ridges, terrace surface and whole terrace. The damage degrees of the terrace ridges were calculated according to the extracted and generalised terrace ridges. The damage degrees of the terrace surface and whole terrace were calculated based on the differences of DEMs before and after degradation. The proposed indices and quantitative methods for evaluating agricultural terrace degradation reflect the erosion status of the terraces in topography. This work provides data and references for loess terrace landscape protection and its sustainable management. Full article
