The application results show that the design is effective for real-time updating of multidimensional data. WebSocket-based platform greatly shortens the time for people to understand and analyze massive and complex multidimensional data. Secondly, for multidimensional data, we further validate the effectiveness of WebSocket in the application scenarios of frequent updating and multi-user concurrent requests. First, on the platform, we compare the network load and network latency above Ajax polling and WebSocket. Based on WebSocket, this paper proposes a multidimensional data service platform architecture that is scalable, real-time and versatile. Nevertheless, traditional real-time communication technology suffers from low efficiency and large bandwidth consumption. Thus, the highly variability of multidimensional data leads to the necessity of improving data management efficiency by updating data in real time. Technology of visualization is critical to analyze multidimensional data which is large-scale. Click any reservoir to view its pop-up.Multidimensional data in different fields (e.g., science and technology resources, medicine, finance and transportation) have emerged in the big data era. In a browser, open the Texas Reservoirs map in Map Viewer Classic.The Performing Overwrite… Success! Elapsed Time message at the end means that the script correctly updated the hosted feature layer. Python OverwriteFS.py learn_user 20af483d68e54ff5835753de0e90ce27 TX_reservoirs_recent_(yourname) c:\Temp\recent-conditions.geojson The command will resemble the following (the item ID will be different, and the path will be a local file path instead of a URL): Realtimes update download#If you download the snapshot of the recent-conditions.geojson file for December 26, 2019, save it to the C:\Temp\ folder that you are working in (replace the existing file). Python OverwriteFS.py learn_user 20af483d68e54ff5835753de0e90ce27 TX_reservoirs_recent_(yourname) If you run it with the URL to the live Texas water site, the command will resemble the following (the item ID will be different): Instead, you can temporarily use a file from, which contains a snapshot of the recent-conditions.geojson file for December 26, 2019. Note:Because you've already created the hosted feature layer using the most recent data, the script won’t make any changes. ![]()
