2020年重庆市GF-2号卫星0.8米融合正射影像数据

该数据集为覆盖重庆市全域8.24万平方公里的高分卫星影像，包括空间分辨率为0.8米的GF-2号卫星融合正射影像，时相以2020年为主，补充2021年1-4月影像，局部补充了Google Earth 0.5米影像，该数据用以生成重庆全域的农业种植地块图斑。

This dataset covers the entire administrative area of Chongqing Municipality (total area: 82,400 square kilometers), and consists of high-resolution satellite imagery. Specifically, it includes orthorectified fused imagery from the GF-2 (Gaofen-2) satellite with a spatial resolution of 0.8 meters. The primary imaging timeframe is 2020, supplemented by imagery collected from January to April 2021, and local regions are further supplemented with 0.5-meter resolution imagery from Google Earth. This dataset is intended for generating agricultural planting land parcels across the entire Chongqing Municipality.
