In big data era, more and more contents and formats in geospatial science. With the development of spatial big data storage, management and analysis, visualization will be the last step for big data applications. Meanwhile, front-end technologies keep iterating, quick transmission for massive to client side is no longer a restriction, allowing users finding patterns in abstract data in a more detailed, more accurate and quicker way.
SuperMap Research Institute adds WebGL rendering mechanism into high-efficiency rendering layer (GraphicLayer), which greatly improves rendering performance. In addition, the version supports any point data with longitude and latitude, like GeoJSON, TopoJSON, chart, it also supports point style changing and interaction operations like attribute filtering and mouse clicking, etc.
Docking with ECharts to Render Million Level Data
In January, 2018, ECharts released version 4.0. The version supports million level data visualization rendering. SuperMap also made improvements, currently, Leaflet, OpenLayers, MapboxGL support ECharts 4.0 rendering.
