The output of the automatic seismic fault detection is a binary image contains fault and background, where one fault may be separated into different fault segments, or several faults are connected with each other which need further distinguish. To reassemble these detected fault segments and construct the fault surface model, four steps are implemented including:1) a morphological workflow is used to separate all connected faults into separated fault segments; 2) the moving least square (MLS) method is used to fit each fault segments as a smooth, one-voxel thickness surface; 3) the weighted principle component analysis (WPCA) method is applied to calculate the normal vector of each surface voxel to judge whether two or more adjacent segments should be combined in one fault surface; 4) MLS method is applied again to fit all surface segments from one fault as an unique fault surface.

This study aimed to estimate aboveground biomass density (AGBD) using environmental covariates and a machine learning approach from the Global Ecosystem Dynamics Investigation Light Detection And Ranging (GEDI-LiDAR) in the Lower Brazos River Watershed, Texas, USA. Specifically, GEDI Level 4A data from the National Aeronautics and Space Administration (NASA) Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) was integrated with Landsat-9 Operational Land Imagery (OLI) and Shuttle Radar Topographic Mission (SRTM) data to enhance predictive accuracy for AGBD. Spectral indices, including the Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI), were derived from Landsat 9 to support AGBD prediction. Three machine learning models, such as Multivariate Adaptive Regression Splines (MARS), Random Forest (RF), and eXtreme Gradient Boosting (XGBoost), were deployed, with performance assessed using the coefficient of determination (R²), root mean square error (RMSE), and mean absolute error (MAE). Among the models, XGBoost achieved the highest predictive accuracy (R² = 0.43, RMSE = 31.03, MAE = 22.49). The modelling indicated that longitude, latitude, moisture stress indices (MSI), and digital elevation model (DEM) are among the critical predictors for AGBD. The mean AGBD across the watershed was estimated at 72.3 Mg ha^-1, corresponding to a total biomass of approximately 66.6 million tons. Evergreen forests showed the highest AGBD values at 110 Mg ha^-1, while cultivated lands averaged 33 Mg ha^-1. These findings highlight the effectiveness of integrating environmental covariates with machine learning to estimate AGBD from GEDI LiDAR across diverse ecosystems. This approach provides a robust tool for advancing carbon management and climate change mitigation efforts, while also supporting data-driven conservation planning in both forested and agricultural landscapes.</div></div>","PeriodicalId":33804,"journal":{"name":"Applied Computing and Geosciences","volume":"27 ","pages":"Article 100289"},"PeriodicalIF":3.2,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145104692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the prompt detection and accurate localisation of landslides are crucial. With the advancement of remote sensing technology and computational methods, artificial intelligence (AI)-based landslide detection techniques have emerged as effective solutions. Compared to traditional methods, these AI-driven approaches offer enhanced efficiency, accuracy and reliability, improving the speed and precision of landslide detection. They also provide valuable data for disaster prevention, mitigation and the assessment of landslide susceptibility and hazard levels. This study focuses on the western Sichuan region and constructs a historical landslide dataset using Google Earth imagery, which includes 4280 landslide samples (3424 for training and 856 for validation). To augment the dataset, 11 data augmentation techniques were applied, including copy–paste, random horizontal flipping, mosaic, random rotation, random hue, saturation and value transformation, affine transformation, random Gaussian noise, random scaling, random brightness and contrast adjustment, mixup and random cropping. These methods improve the diversity of landslide data, helping deep learning models capture more comprehensive global and local information during optimisation. This research utilises the YOLOv10-n object detection framework, enhanced with RepBlock from EfficientRep, FusedMBConv and MBConv techniques derived from EfficientNetV2, CSCGhostblockv2 from GhostNetv2, CReToNeXt from Damo-YOLO and CSCFocalNeXt. These innovations explore the impact of different backbone architectures on model performance. Additionally, the model incorporates four distinct attention mechanisms—convolutional block attention module (CBAM), global attention mechanism(GAM), sim attention module(SimAM) and selective kernel(SK) attention—to assess their influence on detection accuracy. The detection heads are optimised by substituting with three alternatives—DynamicHead, adaptive spatial feature fusion and real-time detection transformer—to enhance feature integration and investigate their effect on model performance. The results indicate that combining EfficientNetV2 with CBAM and v10Detect yields the highest performance. When applied to the historical landslide dataset from the western Sichuan region, the YOLO-EfficientNetV2 model achieves an average precision of 0.861 and an F₁ score of 0.82, with a model size of 5.54 M. This model demonstrates superior capability in accurately identifying landslide locations, addressing the common challenge of balancing detection precision and speed in traditional object detection models, while also reducing parameter size and increasing detection speed.</div></div>","PeriodicalId":33804,"journal":{"name":"Applied Computing and Geosciences","volume":"27 ","pages":"Article 100278"},"PeriodicalIF":3.2,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144917695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multiple-point statistics (MPS) and sequential indicator simulation (SIS) are applied to quantify the probability of channel features from seismic data, away from seismic lines. MPS utilizes training images to capture complex spatial structures, while SIS relies on variogram models for modeling spatial variability. Results demonstrate that denser seismic line spacing (150 m) yields higher accuracy compared to wider spacings (300 m and 600 m), underscoring the importance of data density in offshore subsurface site characterization. Additionally, the findings indicate that MPS provides lower errors, making it preferable for precise channel location prediction. The selected training image did not have a major impact on the outcome on the tested data. Conversely, SIS offers broader coverage of potential channel locations, which may be advantageous for further de-risking.

In the Bushveld Complex (South Africa), potholes range from a few to hundreds of meters in width, and may disrupt orebodies, cause ore loss and pose geotechnical challenges. However, potholes are of scientific value as they are proxies of magma chamber processes that are not directly observable. Unfortunately, it is seldom possible to map the full 3D geometry of potholes directly. Reflection seismics has the potential to map many potholes indirectly. However, the accurate segmentation of potholes in seismic data remains unresolved, particularly using geodata science-based methods. Here, we present a prototype segmentation framework that: (1) uses a physics-based, forward modelling method to synthesize 3D reflection seismic data and augments the training data; and (2) implements a standard deep learning, voxel classification-based pothole detection workflow using the data generated in step (1). Both components of the framework are general enough to permit further development, for example, as deep-learning architectures evolve or as the knowledge of potholes improve. We demonstrate that a self-reinforcing feedback loop of knowledge-driven data engineering and deep learning has the potential to overcome data quality issues in supervised tasks of seismic data analysis. We apply the trained model on augmented data to 3D seismic data acquired from a platinum group element Bushveld Complex orebody and demonstrate that automated pothole prediction is practical.
