Abstract:

Extraction of land use information from very high resolution (VHR) images plays a crucial role in urban planning and management. The study aims to extract urban land use information using VHR images and open geographic data using graph neural networks. We first obtained land cover objects using a semantic segmentation model. The spatial topological relationships between land cover objects were then modeled using graph theory and represented as graph-structured data, in which the attributes of graph nodes were computed based upon points of interest (POI) data and classified land cover map. Last, we used graph neural network to learn high-level structural features for urban land use classification. The proposed method was applied to the core urban area of Fuzhou city, China. Results showed that graph neural networks are effective for urban land use classification from VHR images, and integrating open geographic data further improves the accuracy of urban land use classification to 87% compared to the 84%accuracy obtained by using only VHR images. Our method exhibits high potential for extracting fine-grained urban land use in various urban areas. © COPYRIGHT SPIE. Downloading of the abstract is permitted for personal use only.
