Visualization Analysis for Global Water Resources Based on Digital Earth

Qu, S.; Lv, J., and Liu, J., 2020. Visualization analysis for global water resources based on digital earth. In: Hu, C. and Cai, M. (eds.), Geo-informatics and Oceanography. Journal of Coastal Research, Special Issue No. 105, pp. 47–50. Coconut Creek (Florida), ISSN 0749-0208.The rapid growth of population has placed continuous increasing pressure on water resources. It is of great significance for the sustainable development of water resources to make rational use of limited water resources and to give full play to the maximum use efficiency of water resources. To make rational use of water resources and to protect them, effective monitoring and management of water resources must be performed. To solve this problem, this paper proposes a new method of global water resources monitoring and management, that is, the visual analysis method of global water resources based on digital earth. Through the three-dimensional digital modeling of global water resources, the visual analysis of global water resources is realized, including the distribution of water resources, water area, water resources depth, pollution degree, and other visual analysis, which provides effective means and decision-making basis for water resources monitoring and management.
