资源三号（ZY-3）卫星是中国第一颗自主的民用高分辨率立体测绘卫星，通过立体观测，可以测制1:5万比例尺地形图，为国土资源、农业、林业等领域提供服务。该星于2012年1月9日发射升空。卫星采用经适应性改进的资源二号卫星平台，配置四台相机：
（1）1台地面分辨率优于2.5米的正视全色TDI CCD相机；
（2）2台地面分辨率优于4米的前视、后视全色TDI CCD相机；
（3）1台地面分辨率优于10米的正视多光谱相机。卫星具有测摆功能，可对地球南北纬84度以内的地区实现无缝影像覆盖，每59天实现对我国领土和全球范围的一次影像覆盖，在特殊情况下，能够在5天之内对同一地点进行重访拍摄。
2012年共获取ZY-3影像44景。覆盖范围为整个黑河流域，获取时间（北京时间，每天有多景数据）为：2012-08-25, 2012-09-03, 2012-09-08, 2012-09-13, 2012-09-18, 2012-09-23, 2012-09-28, 2012-10-03, 2012-10-13, 2012-10-18, 2012-10-22, 2012-11-01, 2012-11-11, 2012-11-21。
获取的数据为多光谱模式，分辨率1 m，产品级别为L1。\n黑河流域生态-水文过程综合遥感观测联合试验ZY-3遥感数据集通过购买获取。

Through three-dimensional observation, it can measure and produce 1:50000 scale topographic maps and provide services for land and resources, agriculture, forestry and other fields. The satellite was launched on January 9, 2012. The satellite adopts the Resource-2 satellite platform with improved adaptability and is equipped with four cameras:
（ 1) 1 front view panchromatic TDI CCD camera with ground resolution better than 2.5m
（ 2) 2 sets of front view and back view panchromatic TDI CCD cameras with ground resolution better than 4m
（ 3) 1 front view multispectral camera with ground resolution better than 10m. The satellite has the function of pendulum measurement, which can realize seamless image coverage for areas within 84 degrees of the earth's north-south latitude, and realize image coverage for China's territory and the world every 59 days. Under special circumstances, it can revisit and shoot the same place within 5 days
In 2012, 44 ZY-3 images were obtained. The coverage covers the whole Heihe River Basin, and the acquisition time (Beijing time, there are multiple scene data every day) is: 2012-08-25, 2012-09-03, 2012-09-08, 2012-09-13, 2012-09-18, 2012-09-23, 2012-09-28, 2012-10-03, 2012-10-13, 2012-10-18, 2012-10-22, 2012-11-01, 2012-11-11, 2012-11-21
The acquired data is in multispectral mode, with a resolution of 1 m and a product level of L1.\nThe ZY-3 remote sensing data set of the joint experiment of comprehensive remote sensing observation of ecological hydrological process in Heihe River Basin was obtained through purchase
