251115 EP丨High-resolution Optical-SAR Data for Suzhou Area

Visible light SAR Suzhou area high-resolution data set, composed of Gaofen 2 (GF-2) and Gaofen 3 (GF-3) satellite images, has obtained typical scene data of the Taihu Lake Lake area in Suzhou, Jiangsu Province, China, and can perform visible light and SAR fusion semantic segmentation. The dataset contains 621 standardized image blocks, each with a size of $256 pixels. All images have undergone geometric correction, radiometric calibration, and multi-source data registration processing, effectively eliminating terrain distortion and geometric deviations between modalities, and possessing precise spatial reference and pixel level alignment consistency. The data coverage is extensive, covering various typical land features in urban, rural, and natural environments, divided into six types of land cover: water bodies, forests, farmland, highways, buildings, and unused land, providing high-quality sample support for accurate identification of land features through multimodal data fusion.
