Design and Development of Online Visualization Platform for Meteorological Grid Data
摘要
Abstract
Meteorological grid data is the mainstream format of meteorological numerical forecast, data fusion, reanalysis and other products. However, there are still some problems in reading and using visualization tools of this type of data, such as extreme specialization and complicated configuration of operation environment. Therefore, the grid data can only be used within the industry, and the application scope is greatly limited, it cannot meet the demand of industry, scientific research and social users using grid data. In this paper, B/S, Node. js development framework, WebGIS and D3. js technol-ogy is integrated to develop the functions of installation-free, on-line data interaction and fusion visual display. Besides the tradition spots figure, dynamic wind field is also superimposed to give the comprehensive visual display of the grid data. In this paper, T639 numerical forecast data are used to test the platform. The results show that this system can objectively reflect the data content, while the dynamic wind field display is better for users to understand the data. The platform improves the display efficiency of grid data and provides a practical, convenient and effective tool for relating visual anal- ysis to spatial region of grid data and multiple elements. At the same time, the structural development can also provide an open docking channel for visual integration with numerical prediction and re-analysis system.关键词
