High-performance
PTV AJAX Maps

One of the primary use cases of the PTV AJAX Maps component is displaying objects on a map. This may be POIs or vehicles or anything else with a geographic location and a graphical representation. In addition to drawing these objects, you often want them to be interactive, e.g. by displaying a tooltip when the cursor is hovering over them.

If you only want to show a few dozen objects, there are two built-in approaches that don’t require any special code or architecture:
– You can add your objects completely via JavaScript in the browser, or
– you can let the PTV xMap Server draw them for you.

In the latter case, the PTV AJAX Maps component automatically requests the associated meta-data in order to create tooltips or clickable areas.

Things get a little trickier when you need to display hundreds, thousands, or even millions of objects. This requires a scalable architecture with an appropriate distribution of work between your application, the PTV xMap Server, and the PTV AJAX Maps client in the browser.

The upcoming advanced level session “High-performance PTV AJAX Maps” provides you with an approach for these scenarios that enables you to create responsive, scalable applications that are not limited by browser speed or network bandwidth. We’ll be touching topics like

  • stateful and stateless servers,
  • client-side and server-side drawing,
  • and – perhaps most importantly – clustering of objects so that neither the user nor the browser is overloaded with data.
