HiWATER: BNUNET soil moisture and LST observation dataset in the middle reaches of the Heihe River Basin

This dataset includes soil moisture and soil temperature observations of 75 BNUNET nodes during the period from May to September 2012 (UTC+8), which is one type of WSN nodes in the Heihe eco-hydrological wireless sensor network (WSN). The BNUNET located in the observation matrix of the HiWATER artificial oasis eco-hydrology experimental area. Each BNUNET node observes the soil temperature at 4 cm,...

HiWATER: Dataset of Vegetation Type and Plant Structure Investigation in the middle reaches of the Heihe River Basin

The dataset contains vegetation type and plant structure in the middle reaches of the Heihe River Basin, which was used to validate products from remote sensing. It was generated from investigating the land cover strips of CASI and SASI the middle reaches of the Heihe River Basin between 25 June and 6 August in 2012.
Instruments: High-precision handheld GPS (2-3 m) and digital camera were used as ...

HiWATER: Dataset of surface temperature of orchard in the middle reaches of the Heihe River Basin

HiWATER: 0.5m WorldView-2DOM data production in Dayekou Basin

Trough the select tasking, we obtained the WorldView-2 stereo image data in Dayekou Watershed production in mid-May 2012. In the same year from July to August, 27 GPS ground control points (GCP) and checkpoints were measured based on the watershed differential GPS control network. Based on the full-field GCPs, the rational polynomial coefficients (RPC) files of WorldView-2 images were corrected in...
