XDA28100501 - Multi-Load Aerial Flight Dataset of Youyi Farm, Sanjiang Demonstration Area, China

Its total data volume is approximately 33.83 GB, and the coverage area of single-phase sample data is 1 km² each. Centered on benchmark data acquired from cooperative observation via multi-sensors mounted on aerial platforms, the dataset sorting and submission of benchmark data totaling 30.8 GB were completed in three phases in strict accordance with flight test schedules: Phase I (October 2022) mainly submitted 2.48 GB of sample data from cooperative observation by multispectral and optical cameras; Phase II (April–May 2023) delivered 13.8 GB of sample data jointly collected by multispectral cameras, full-spectrum hyperspectral cameras and multi-dimensional SAR sensors; Phase III (June–July 2023) provided 14.5 GB of integrated sample data combining hyperspectral and multi-dimensional SAR observations, establishing a multi-dimensional, full-element benchmark verification system for aerial remote sensing.

To address the absence or insufficient coverage of thermal infrared sensor data during aerial flight tests at Youyi Farm in Shuangyashan, Heilongjiang Province, the research team coordinated multiple domestic high-resolution satellites to conduct strictly time-space synchronized overpass observations. Matching satellite thermal infrared data were acquired as auxiliary samples and verification support, including synchronous thermal infrared imaging samples from HJ2B-IRS (Product ID: 564226, 2.10 GB), GF5A-WTI (Product ID: 25903, 733.31 MB) and ZY1F-IRS (Product ID: 480617, 215.53 MB).
