We will demonstrate a solution to utilize Esri +D65JS API 4.17, along with OpenGL Custom layer to show the Esri JS API's capability of consuming, analyzing, and visualizing BIG environmental telemetry monitoring DATA by displaying the data in a web map with animation for better user experience. The solution is based on custom solution we build on JS API 3.x, where we had to use a middle tier to convert regular live JSON data feed to GeoJSON and then to Esri JSON to add to a web map. This new approach converts data directly to feature layer. -------------------------------------------------------------------------------------------------------------------------- Follow us on Social Media!
