Special Issue Information

Dear Colleagues,

This Special Issue focuses on terrestrial vegetation and ecosystem services mapping using multi-source remote sensing data, including optical, synthetic aperture radar (SAR) and LiDAR.

Vegetation cover is terrestrially ubiquitous and spatially uneven, ranging from mosses, grasslands, shrublands, mangroves and forests, which provide habitat, shelter, protection and food for various life forms, thereby supporting biodiversity.

However, vegetation is impacted by natural variability and human disturbances, necessitating the monitoring and mapping of the ecosystem services for effective management and conservation. The application of multi-source remote-sensing approaches provides accurate and cost-efficient mapping of vegetation and ecosystem services, particularly for monitoring programs at ecosystem and landscape scales. The advent of AI, including machine-learning and deep-learning algorithms, has extended the capabilities of remote sensing for mapping vegetation and ecosystem services.

This Special Issue aims to highlight cutting-edge research works that apply multiple remote-sensing data collected through aerial and satellite systems, as well as AI methods, for mapping vegetation (including mosses, lichens, grasslands, shrubs, mangroves and forests) and ecosystem services. We welcome vegetation and ecosystem services mapping works from all major biomes, including the Antarctic tundra.

Topics for this Special Issue include, but are not limited to, the following:

  • New algorithms and products from UAV and satellite observations for mapping vegetation in desert, grassland, aquatic, forest and tundra biomes.
  • Integration of optical, SAR and LiDAR observations for ecosystem services mapping, including mangrove and forest carbon-stock estimation.
  • New algorithms for mapping trees and aboveground biomass of savanna ecosystems.
  • Application of multitemporal satellite-based optical and SAR for groundwater dependent ecosystems, grassland and invasive plant mapping

We encourage authors to submit original research articles, review articles and short communications related to innovative techniques and applications of optical, SAR and LiDAR for vegetation mapping and ecosystem services. Short communications should address pertinent issues on emerging mapping techniques of high importance to the remote-sensing community.

Forest, shrubland, and grassland exhibit highly overlapping characteristics, and single-modal remote sensing data cannot simultaneously capture both spectral and structural information. Moreover, multimodal fusion learning of optical and SAR data faces challenges such as the lack of high-quality samples and difficulties in effective cross-modal feature fusion. Therefore, a high-resolution multimodal remote sensing feature dataset (GF23FSG) is constructed for the fine classification of forest, shrubland, and grassland, and a Cross-modal Adaptive Structure Fusion Network (CASFNet) is proposed. In response to the feature heterogeneity of optical and SAR, a cross-modal adaptive fusion module based on spatial alignment and a dynamic weight allocation strategy is proposed, which effectively enhances the learning of spectral–spectrum heterogeneous features. In addition, a multi-level auxiliary supervision mechanism is introduced to strengthen feature representation learning. Gradient constraints are further imposed on deep-level features to improve the model’s ability to capture and learn deep cross-modal representations, thereby effectively mitigating representation degradation during the feature fusion process. Experiments on the self-constructed GF23FSG dataset and the publicly available SEN12MS dataset achieve OA of 77.38% and 71.84%, respectively, demonstrating superior classification performance compared with SOTA methods. In addition, comparative analysis with public land cover products and field samples further confirm the reliability and generalization performance of the proposed dataset and model for the fine classification of forest, shrubland, and grassland. This study provides a new solution for the fine classification of forest, shrubland, and grassland from multimodal remote sensing images from the perspectives of dataset construction and methodological design.
