Special Issue Information

Dear Colleagues,

Recently, with the advancement of technology, the applications of remote sensing data in environmental protection and sustainable development are becoming more and more popular. However, big remote sensing data also bring some problems such as how to effectively and efficiently process these remote sensing data. Machine learning and deep learning are the keys to this trend. Therefore, this Special Issue of Sustainability aims to demonstrate state-of-the-art works in employing machine learning, deep learning, and image processing algorithms in remote sensing data for environmental applications.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Hyperspectral, multispectral image processing
  • Machine learning/Deep learning/Image processing for hyperspectral, multispectral data analysis
  • Machine learning/Deep learning/Image processing in environmental analysis
  • Remote Sensing applications in environment/sustainability
  • Data mining and the development of statistical models in remote sensing data
  • Signal processing in remote sensing data analysis
  • Sustainability concepts in remote sensing applications

We look forward to receiving your contributions.

The detection of black and odorous water using remote sensing technology has become an effective method. The high-resolution remote sensing images can extract target features better than low-resolution images. However, the high-resolution images often introduce complex background details and intricate textures, which often have problems with accurate feature extraction. In this paper, based on remote sensing images acquired by the Gaofen-2 satellite, we proposed a Modified DeepLabv3+ model to detect black and odorous water. To reduce the complexity of the encoder part of the model, Modified Deeplabv3+ incorporates a lightweight MobileNetV2 network. A convolutional attention module was introduced to improve the focus on the features of black and odorous water. Then, a fuzzy block was crafted to reduce the uncertainty of the raw data. Additionally, a new loss function was formulated to solve the problem of category imbalance. A series of experiments were conducted on both remote sensing images for the black and odorous water detection (RSBD) dataset and the water pollution dataset, demonstrating that the Modified DeepLabv3+ model outperforms other commonly used semantic segmentation networks. It effectively captures detailed information and reduces image segmentation errors. In addition, in order to better identify black and odorous water and enrich the spectral information of the image, we have generated derived bands using the black and odorous water index. These derived bands were fused together with the original image to construct the RSBD-II dataset. The experimental results show that adding a black and odorous water feature index can achieve a better detection effect. Full article
