AB  - During the middle reaches aerial remote sensing test in 2012, the land cover within the CASI + Sasi flight belt in the middle reaches of Heihe River was investigated in order to obtain the data of main vegetation types and planting structures for the authenticity test of vegetation remote sensing products. Observation instrument: High precision handheld GPS (positioning accuracy 2-3m) and digital camera. Measurement method: With 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. Data content: The data content includes longitude and latitude, vegetation type, approximate planting area, crop climate and other information. Observation location: It 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). Observation time: The investigation began on June 25, 2012 and ended on August 6, 2012
