AIRSAT-Water-1.0: High-Resolution SAR Monitoring of Water Bodies Dataset

The AIRSAT-Water-1.0 dataset is a SAR classification dataset for high-resolution water monitoring, supported by Zhongke Satellite Technology Group Co., Ltd. The company has the full industry chain capability from satellite design and sales, SAR payload development and delivery, satellite measurement and control, data reception and processing, data sales and value-added services, satellite operation to aviation remote sensing services. At present, we have independently operated the AIRSAT commercial remote sensing satellite system, with a total of 10 in orbit satellites (including 7 SAR satellites), which have the ability to obtain and serve aerospace remote sensing data 24/7, with multiple means, high frequency, and low cost. We provide one-stop intelligent data solutions for global commercial remote sensing customers. This dataset covers multi-source image data obtained by AIRSAT series satellites in different working modes and frequency bands. Typical scene samples from multiple time and space, and across frequency bands were selected, consisting of 25 sets of AIRSAT-01, AIRSAT-05, and AIRSAT-08 satellite data from different regions. Among them, AIRSAT-01/02 satellite adopts Ku band and single polarization (HH) mode, with a spatial resolution of 2 m and a width of 16-18 km; AIRSAT-05 satellite adopts X-band and dual polarization (HH/HV) mode, with a resolution of 3 m and a width of 30 km; AIRSAT-08 satellite adopts X-band and dual polarization (HH/HV) mode, with a resolution of 1 m and a width of 10 km; All images are L2 level system geometric correction products, which complete geometric positioning, map projection, radiation correction and resampling processing based on satellite attitude and orbit data, with accurate spatial reference and geometric consistency. The data format is GeoTIFF. The data coverage is extensive, including typical land types such as water bodies, buildings, vegetation, bare land, roads, farmland, and mountains, providing diverse sample support for water body recognition in complex backgrounds.
