Abstract:

Acquiring the key information which reflects the growth of crops efficiently and normatively are important for crop yield estimation and growth forecast by remote sensing technology. In our research, the key information acquisition standard is constructed by the definition of acquired targets filtration, sampling point design, data collection methods, data processing and others. Taking rice-paddy fild?s environment system for example, the field data collection point selection and the acquisition path analysis of rice paddy are guided with this key information acquisition standard, and also the finish of obtaining the key data about ground observation and weather. These data provide an important support for the construction and validation of the rice yield estimation model with the combination of remote sensing data and field data. Finally, the paper presents a further recommendation for improvement when this standard used in a large-area crop field?s environment.
