The application showcases the construction of the current buildings of New York over time. The demo features a widget that displays information about the buildings currently built at a given time in in the view extent. The queries required to update the widget are executed client-side, avoiding round trips to the service. It uses web workers, spatial indexing and a SQL engine.

The longitude and latitude coordinates are projected client side in the view’s projection by the projection engine, the same available in ArcGIS Pro and Runtime. It’s compiled as a WebAssembly module and streamed to the web browser.
