Web-based Geovisualization System of Oceanographic Information using Dynamic particles and HTML']HTML5

A web-based geovisualization system of oceanographic information using dynamic particles and HTML5 has been established to address the limitations of the existing Web-GIS based oceanographic information system. The limitations include systematic scalability, slow service speed, a non-standard intemet web environment, poor user accessibility and interactivity, and spatial and temporal variability visualization. Importantly, spatial observation data through remote sensing and 3D numerical modeling data are oceanographic data having spatial and temporal variability. Such data are heterogeneous, large capacity, and multidimensional and are based on geographic information. In order to understand intuitively and analyze effectively, dynamic particles were applied to visualize the spatial and temporal variability. This paper introduces the oceanographic information geovisualization system, in which the information inquiry and analysis functions are implemented using open libraries such as HTML5, WebGL, Canvas, D3, and Leaflet map, which are next generation Web platform standards for multimedia service and map with location service.
