A feature perturbation weakly supervised learning network for airborne multispectral LiDAR pointcloud classification Int. J. Appl. Earth Obs. Geoinf. (IF 7.5) Pub Date : 2024-01-29 Ke Chen, Haiyan Guan, Lanying Wang, Yongtao Yu, Yufu Zang, Nannan Qin, Jiacheng Liu, Jonathan Li
Currently, most pointcloud classification methods heavily rely on huge numbers of labeled samples. Notably, labeling a large-scale multispectral LiDAR (MS-LiDAR) pointcloud is time-consuming and costly. To address this issue, we propose a feature perturbation weakly supervised network for classifying MS-LiDAR pointclouds using a few labeled samples, termed as FPWS-Net. In the FPWS-Net, we innovatively

A self-adaptive wildfire detection algorithm by fusing physical and deep learning schemes Int. J. Appl. Earth Obs. Geoinf. (IF 7.5) Pub Date : 2024-01-27 Shuting Jin, Tianxing Wang, Huabing Huang, Xiaopo Zheng, Tongwen Li, Zhou Guo
Currently, the spectra-based physical models and deep learning methods are frequently used to detect wildfires from remote sensing data. However, physical algorithms mainly rely on radiative transfer processes, which limit their effectiveness in detecting small and weak fires. On the other hand, deep learning methods usually lack mechanism constraints, thus generally resulting in false alarms of bright

A spatiotemporal framework for the joint risk assessments of urban flood and urban heat island Int. J. Appl. Earth Obs. Geoinf. (IF 7.5) Pub Date : 2024-01-28 Xianzhe Tang, Xi Huang, Juwei Tian, Yuhao Jiang, Xue Ding, Wei Liu
Urban Flood (UF) and Urban Heat Island (UHI) become prevalent “urban diseases” currently. Previous studies usually regarded UF and UHI as separate issues that requires respective concentration; however, UF and UHI are inextricably connected so that they should be considered together. Hence, this paper proposes a spatiotemporal framework to link UF and UHI by developing an Urban Flood Heat Island (UFHI)

Integrating cellular automata with long short-term memory neural network to simulate urban expansion using time-series data Int. J. Appl. Earth Obs. Geoinf. (IF 7.5) Pub Date : 2024-01-25 Zihao Zhou, Yimin Chen, Zhensheng Wang, Feidong Lu
Cellular automata (CA) have been widely used to simulate urban expansion. However, previous studies rarely explored how to extract transition rules from time-series urban extent maps, hence modeling the temporal dependency of urban expansion process. To solve this issue, this study proposes a novel CA model based on the long-short term memory method (LSTM-CA). The LSTM-CA model combines artificial

Exploring region features in remote sensing image captioning Int. J. Appl. Earth Obs. Geoinf. (IF 7.5) Pub Date : 2024-01-25 Kai Zhao, Wei Xiong
Remote sensing image captioning (RSIC), an emerging field of cross-modal tasks, has become a popular research topic in recent years. Feature extraction underlies all RSIC tasks, with current tasks using grid features. Compared with grid features, region features provide object-level location-related information; however, these features have not been considered in the RSIC tasks. Therefore, this study

Accurate vegetation destruction detection using remote sensing imagery based on the three-band difference vegetation index (TBDVI) and dual-temporal detection method Int. J. Appl. Earth Obs. Geoinf. (IF 7.5) Pub Date : 2024-01-25 Chuanwu Zhao, Yaozhong Pan, Shoujia Ren, Yuan Gao, Hanyi Wu, Gelilan Ma
Satellite remote sensing, as an important tool for Earth observation, has been widely used to monitor various vegetation destruction events (VDEs), such as logging, wildfires and insect infestations. However, due to the spectral diversity of VDE and the complexity of background environments (BE), achieving accurate VDE detection remains a challenge. To overcome this limitation, this study developed

Robust multi-view UAV SAR image registration based on selective correlation of log gradient descriptor Int. J. Appl. Earth Obs. Geoinf. (IF 7.5) Pub Date : 2024-01-25 Xin Xiong, Guowang Jin, Qing Xu, Xiangyun Liu, Quanjie Shi
Unmanned aerial vehicle (UAV) synthetic aperture radar (SAR) image characteristics, such as large geometric distortions, striped inhomogeneous radiation, severe speckle noise and ultra-high resolution, pose significant challenges to multi-view UAV SAR image registration. To address these issues, we propose a robust multi-view UAV SAR image registration algorithm based on the selective correlation of
