Agriculture is the largest consumer of freshwater, and attention has been focused on improving water-use efficiency in irrigated agriculture. We propose 3-D light detection and ranging (LiDAR)-based semantic simultaneous localization and mapping using unmanned aerial vehicles (UAVs) for intelligent irrigation. The proposed system uses the water-absorbing property of LiDAR to define a water point cloud and segment the surface water area based on singular value decomposition. A path is created using random sample consensus as the median point of the divided surface water area. By extracting the width and height information from the surrounding point cloud, the system aids in proactive natural disaster prevention and has potential applications for Big Data. The performance and practical utility of the proposed system were demonstrated via field data using a UAV and 3-D LiDAR. The robustness of the proposed system is verified by experiments in two irrigation environments with different surface water widths and temporal conditions.","PeriodicalId":13116,"journal":{"name":"IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing","volume":"18 ","pages":"7495-7508"},"PeriodicalIF":4.7,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10909471","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most GNSS-R instruments conduct 1 ms coherent integration, followed by 500 or 1000 incoherent averages, leading to level-1 products [delay Doppler map (DDM)]. For remote sensing missions with higher spatio-temporal resolution requirements, raw data, and fewer incoherent averages are required for DDM computations. Fengyun-3E (FY-3E) GNSS Occultation Sounder II (GNOS-II) payload can acquire reflected signal's intermediate frequency (IF) raw data for specific areas, but there is no channel to record raw direct signals. Obtaining level-1 products DDM from raw data requires tracking the delay and Doppler frequency centroid coordinates, as they change during the incoherent integration time. Otherwise, the level-1 DDMs would appear blurring, which would result in wider DDMs and lower peaks. Besides, the geometry of transmitter-specular reflection point-receiver of GNOS-II is unobtainable, so classical algorithms cannot be used. Therefore, an innovative processing technique is presented, which can estimate the peak coordinates of all individual DDMs by appropriately grouping the individual DDMs and incoherently accumulating within each group. The feasibility of this method is demonstrated with representative data from sea, ice, and soil. Furthermore, incoherent averaging DDMs at a temporal resolution of 200 ms can well detect the boundary between sea, ice, and soil in high-latitude and complex environments while maintaining high quality. This work is an important basis for future analysis of the raw data from GNOS-II and will also inspire other work of individual DDM tracking where geometric information is agnostic.","PeriodicalId":13116,"journal":{"name":"IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing","volume":"18 ","pages":"8040-8056"},"PeriodicalIF":4.7,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10908653","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to low spatial resolution and difficulty in obtaining HS images, spectral target detection based on it faces extremely serious problems of small-scale and mixed spectra. To address this problem, taking the more easily obtained high-spatial-resolution multispectral (HMS) image as an appropriate input, this article proposes a specific spectral target detection method through target-focused spectral super-resolution (SSR). Specifically, by taking the given target spectrum and the spectral library as priors, a target-focused SSR model under the sparse representation framework is proposed first, to enrich the spectral information of the HMS image, and to accurately reconstruct the corresponding high-spatial-resolution HS image, especially for the target area. Then, a target-specific band selection strategy is designed, to extract the most distinguishable spectral bands against background, which can enhance the separation between the target and background and help to reduce the false alarm rate of the detection. Finally, a background separation-based spectral target detection method for the selected bands is proposed, to locate the spectral targets directly by using the optimized target sparse coefficient matrix. Experimental results on four different datasets show that, our proposed method achieves the best target detection performance in comparison to other relative state-of-the-art methods, and can even efficiently handle the detection of subpixel-level spectral targets through this unmixing-like spectral dictionary expression.","PeriodicalId":13116,"journal":{"name":"IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing","volume":"18 ","pages":"7529-7542"},"PeriodicalIF":4.7,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10909183","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, RSI scene classification still faces challenges such as complex multiscale key features concentrated in different local regions, large interclass imbalance, and intraclass variation in insufficient well-labeled RSI samples. To address these challenges, we proposed a novel RSI scene classification method based on an improved vision transformer. This method has better multiscale feature representation ability due to the improved hierarchical vision transformer structure, in which a feature map fusion layer produces feature maps of different sizes, and a window transformer block with dynamic window shift unit actively shifts to the local region with dense information, flexibly extracting and associating key features with multiscale in different input regions. Furthermore, we design a curriculum transfer learning framework to alleviate the problems of lacking well-labeled training samples, intraclass variation, and interclass imbalance during the training process of the improved vision transformer. This framework employs a dual-criteria difficulty evaluator to evaluate training samples and provides supplementary supervision to the model by generating training task schedules. Finally, experimental results demonstrate that the proposed vision transformer model achieves rapid convergence and superior performance in RSI scene classification task.","PeriodicalId":13116,"journal":{"name":"IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing","volume":"18 ","pages":"8011-8024"},"PeriodicalIF":4.7,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10908633","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accurate quantification and inversion of oil spills and emulsions are essential for an effective emergency response. This study systematically investigated oil spill quantitative inversion from land-based to airborne and then to satellite-based, focusing on the optical and thermal response characteristics of nonemulsified crude oils (NEO) and fuel oils of varying thicknesses, as well as oil spill emulsions (OE) with different emulsification concentrations. A novel modular oil spill quantitative inversion model (OQIM) combining optical and thermal characteristics was developed, which comprehensively utilized the inversion advantages of optical and thermal infrared remote sensing in the thin and thick oil film ranges, respectively, enabling the simultaneous quantitative inversion of NEO and OE. The study demonstrates that the OQIM exhibited excellent quantitative inversion capabilities and stability under ideal land-based scenarios, with <italic>R</i><sup>2</sup>; values for NEO and OE exceeding 0.978 and 0.983, respectively. The OQIM effectively utilized the technical strengths of optical and thermal remote sensing, successfully mitigating the interference from sun glint, and inverting the thickness of NEO and fuel oil based on the UAV actual measurement data. By employing the oil–water brightness temperature difference polar coordinate thermal model, the absolute thickness of the oil-in-water emulsions was inverted with an average relative error below 12.7%. When applied to airborne and satellite remote sensing images of actual oil spill incidents, the OQIM model exhibited significant inversion potential and generalization capabilities in practical applications, offering crucial methodological support for emergency responses to marine oil spills.","PeriodicalId":13116,"journal":{"name":"IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing","volume":"18 ","pages":"8472-8489"},"PeriodicalIF":4.7,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10909410","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The merged dataset was developed to expand the generalization and variation of data distribution associated with the labeling and training processes inherent in satellite image analysis. We systematically collected prediction results for each individual dataset and conducted a comparative analysis against results reported in previous studies to benchmark the model's effectiveness. The findings indicate that large language models (LLMs), such as MiniCPM-V, exhibit promising capabilities in the realm of satellite image recognition. On the RSSCN7 dataset, MiniCPM-V achieved an accuracy of 70.57%, while on RSICD it reached 62.19%, on MAI 7.01%, and on the merged dataset 43.49% . Specifically, the model demonstrated mostly high accuracy (more than 80% ) in identifying a majority of object classes across the datasets. Also, we identified, it underperformed in accurately classifying certain object categories and recognizing all objects in multilabeled images, which suggests that while the model is robust overall, there are specific areas where its performance can be enhanced. Despite these limitations, the successful recognition of most objects underscores the potential of LLMs in advancing satellite imagery analysis. These results highlight the significant potential of integrating LLMs into remote sensing applications, offering a foundation for future research aimed at improving classification accuracy and expanding the range of detectable object classes by having caption level textual information.","PeriodicalId":13116,"journal":{"name":"IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing","volume":"18 ","pages":"7892-7903"},"PeriodicalIF":4.7,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10908656","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, tensor completion has been presented for image recovery. Owing to the framelet basis redundancy, the tensor rank of the extended tensor via feature extraction is smaller, which can characterize the correlation between any two modes of the tensor more accurately. In this work, the fully connected tensor network decomposition has been suggested to depict the low-rankness of the extended tensor with feature extraction. The process of feature extraction via framelet transform reduces the need for fewer principal components to depict the low-rankness of the underlying tensor. Moreover, total variation is incorporated into the proposed completion model to capture the spatial smoothness of the underlying tensor via minimizing the sum of the gradients across the image. To solve the large-scale resulting model, the augmented Lagrange multiplier-based proximal alternating minimization algorithm has been proposed. To accelerate the optimization algorithm, the leverage score sampling and fast Fourier transform have been introduced. Numerical results on several types of hyperspectral image completion problem demonstrate that the proposed method performs better than the compared methods in data completion.","PeriodicalId":13116,"journal":{"name":"IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing","volume":"18 ","pages":"7543-7558"},"PeriodicalIF":4.7,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10908089","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, a multilevel point-matching algorithm based on hierarchical feature detection and description is proposed in this letter to improve the accuracy of SAR-to-optical (S-O) image registration. First, a FAST feature detector (OIPC-Fast) is constructed by combining overlapping chunking, image stratification, and phase congruency (PC). The OIPC-Fast detector performs hierarchical feature detection on SAR and optical images based on image properties by two-dimensional discrete wavelet transform and multimoment of PC map, respectively. Feature points with high consistency are screened out by voting criteria. The repeatability of keypoints is effectively improved. Then, a multilevel matching strategy is proposed. The SAR feature descriptor is constructed in this strategy by capturing more layers of image information rather than using a single denoised SAR image information after preprocessing, thus enhancing the robustness of SAR feature descriptors. Ten sets of real image data are used for experimental validation. Compared with some of the most advanced algorithms, the results indicate that the registration accuracy can be improved by applying the proposed point-matching algorithm to S-O image registration.","PeriodicalId":13116,"journal":{"name":"IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing","volume":"18 ","pages":"7318-7333"},"PeriodicalIF":4.7,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10906637","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
