在2012年中游航空遥感试验开展期间，对黑河中游CASI+SASI飞行航带范围内土地覆盖开展调查，目的在于获取主要的植被类型和种植结构数据，用于实现植被遥感产品的真实性检验。\n
\n观测仪器：\n
\n高精度手持GPS（定位精度2-3米）和数码相机。\n
\n测量方式：\n
\n借助Goole Earth，可以大致看出中游有植被的范围， 设计具体路线，然后选择小满镇五星村的5*5公里为主要详细调查范围，实验调查可行的基础上，对中游其他做大面积调查，在尽可能到达的路线内具体调查种植结构类型。调查的方式是尽量选择大面积均质的植被类型或者农田进行调查，记录坐标位置、拍摄下垫面照片。\n
\n数据内容：\n
\n数据内容包含经纬度，植被类型，大概的种植面积，作物的物侯期等信息。\n
\n观测地点：\n
\n重点为中游人工绿洲试验区CASI飞行区域，还包括CASI在中游样带飞行区域和黑河中游2区（甘州、肃州）5县（山丹、民乐、临泽、高台、金塔）。\n
\n观测时间：\n
\n本次调查时间从2012年6月25日开始，8月6日结束。

\nObservation instrument:\n
\nHigh precision handheld GPS (positioning accuracy 2-3m) and digital camera.\n
\nMeasurement method:\n
\nWith the help of Google Earth, we can roughly see the range of vegetation in the middle reaches, design the specific route, and then select 5 * 5km from Wuxing village, Xiaoman town as the main detailed investigation range. On the basis of feasible experimental investigation, we will conduct a large-scale investigation on other areas in the middle reaches, and specifically investigate the type of planting structure within the route as far as possible. The way of investigation is to select large-area homogeneous vegetation types or farmland for investigation, record coordinate positions and take photos of underlying surface.\n
\nData content:\n
\nThe data content includes longitude and latitude, vegetation type, approximate planting area, crop climate and other information.\n
\nObservation location:\n
\nIt focuses on the CASI flight area in the pilot area of artificial oasis in the middle reaches, including the CASI flight area in the sample belt in the middle reaches and 5 counties (Shandan, Minle, Linze, Gaotai and Jinta) in zone 2 of the middle reaches of Heihe River (Ganzhou and Suzhou).\n
\nObservation time:\n
\nThe investigation began on June 25, 2012 and ended on August 6, 2012
