Instruments: High-precision handheld GPS (2-3 m) and digital camera were used as main tools in the survey.
Measurement method: Hierarchical classification is applied based on CASI data. According to various land types, pixel classifications is used for forest, grassland, bare land and building lands; in-situ observations and investigations are used for different crops.
Dataset contains: land types, including maize, leek, poplar trees, cauliflower, bell pepper, potatoes, endive sprout, orchard, watermelon, kidney bean, pear orchard, shadow, and non-vegetation, except for 14 others which are not classified.
Observation site: core experimental areas with 5*5 matrix structure in the middle reaches of the Heihe river basin
Date: From 25 June in 2012 (UTC+8) on.
