One system of data fusion for monitoring crop yield based on RS and GIS is developed. This system essentially plays two roles: implementing the information from RS and GIS associated with crop yield modeling, and increasing precision of crop yield modeling by the information representing physical and logical fusion objects subject to the crop yield monitoring.
Geographic information system (GIS) can deal with large quantity of data efficiently. Based on GIS, this paper researches the ambient air pollution and establishes dynamic databases of the atmospheric environment in Jiaozuo city. Through analyzing a plenty of spatial data systematically, this article establishes dynamic simulation models and the spatial analysis models on ambient air quality. The...
This paper proposes a research framework for studying urban air pollution. The framework generalizes the comprehensive thinking and process of urban air pollution research from a GIS-based perspective and pays more attention to the spatial distribution of air pollution. It includes three sections in sequence of data acquisition, model running and result applications. The authors utilize spatial data...
The snow-covered information, including snow-covered area, snow depth and snow water equivalent have been extracted from the remote sensing imagery of CBERS-02 satellite over the area of Jiaodong Peninsula in west Shandong Province, one of the snowiest regions in China. Based on the pre-processing of remote sensing data of CBERS-02 imagery, the statistical analysis of spectral characteristics has...
