江苏省南京市鼓楼区鼓楼广场低空影像数据集

该数据集主要覆盖南京市鼓楼广场及周边区域，通过无人机或低空飞行器采集的高分辨率航空影像数据。核心特征包括：
• 分辨率：可达0.2米级，符合江苏省基础航空摄影标准（如2023年全省航摄项目）。
• 内容：包含可见光影像、正射影像图（DOM）、数字表面模型（DSM）等，记录地表建筑、植被、交通设施等细节。
• 时效性：数据持续更新，例如2023年江苏省航摄项目覆盖南京主城区，鼓楼广场作为重点区域被纳入。
• 技术标准：遵循《低空数字航摄与数据处理规范》（GB/T 39612-2020），确保几何精度与影像质量。

This dataset primarily covers Gulou Square and its surrounding areas in Nanjing, comprising high-resolution aerial imagery collected via unmanned aerial vehicles (UAVs) or low-altitude aircraft. Its core characteristics include:
• Resolution: Up to 0.2-meter ground sampling distance, complying with the basic aerial photography standards of Jiangsu Province (e.g., the 2023 provincial aerial photography project).
• Content: Includes visible light images, Digital Orthophoto Map (DOM), Digital Surface Model (DSM) and other geospatial data products, recording detailed information such as surface buildings, vegetation, transportation infrastructure and other relevant elements.
• Timeliness: The data is continuously updated. For example, the 2023 Jiangsu Provincial Aerial Photography Project covered the main urban area of Nanjing, and Gulou Square was included as a key coverage area.
• Technical Specifications: Complies with the Specifications for Low-altitude Digital Aerial Photography and Data Processing (GB/T 39612-2020) to ensure geometric accuracy and image quality.
