该数据集包含土耳其伊斯坦布尔Fatih地区的Mapillary街景图像，并提供了元数据和多个衍生分析层。所有数据层通过唯一的image_id进行关联。数据集包括原始图像（以WebDataset分片存储）、元数据清单（包含坐标、拍摄时间、相机信息等）、VLM生成的GeoAI描述（使用Qwen/Qwen3-VL-4B-Instruct模型生成）、基于Cityscapes-19的语义分割输出（使用Ultralytics YOLO模型生成），以及ZenSVI生成的人类感知和眩光分类输出。数据覆盖Fatih的OpenStreetMap行政边界，适用于地理人工智能、计算机视觉和城市分析任务。原始图像遵循CC BY-SA 4.0许可证。

This dataset contains street-level Mapillary images for Fatih, Istanbul, along with metadata and derived analysis layers. All layers are linked by a stable join key image_id. It includes raw images stored as WebDataset shards, a manifest with metadata (coordinates, capture time, camera info), VLM-generated GeoAI descriptions (produced using Qwen/Qwen3-VL-4B-Instruct), Cityscapes-19 semantic segmentation outputs (generated with an Ultralytics YOLO model), and ZenSVI human perception and glare classifier outputs. The data is filtered to the OpenStreetMap administrative boundary of Fatih and is suitable for geoAI, computer vision, and urban analysis tasks. The raw images are shared under the CC BY-SA 4.0 license.
