Tracking Client API ConceptsAdam Mollenkopf

Tracking Client API Concepts

• The Tracking Client API allows you to enable applications with Real-Time data

• Developer libraries are available for use with Flex, Silverlight, Java, and .NET.

• Tracking Client APIs can be found on Esri Resources under ‘Solutions Products – Tracking Server’.

• http://resources.arcgis.com/

Tracking Client API Concepts

• The starting point for working with the Tracking Client API is the Connector class. Connector provides you with the ability to:

• Connect and Authenticate with a Tracking Server• Get a List of available Tracking Services• Subscribe to a Tracking Service

• The Tracking Client API uses an Asynchronous event model.

• Responses and Events are delivered on a subscription basis, so listeners need to be registered to handle them.

Other ConsiderationsAdam Mollenkopf

Other Considerations

• Using Historical Data• Time Aware Layers via Feature Services

• Data Augmentation• Joining static data into Tracks – Server vs. Client

• Client Side Rendering• Temporal Renderers, Aging• Strategies for Client side purging

• Data Volume Considerations• Feature Logging• Archival Strategies• Tracking Server history – Track vs. Time

Summary

• The Tracking Client API• enables ArcGIS with Real-Time data

• offers unified functionality across a variety of developer platforms including:

• Flex, Silverlight, .NET, and Java

• works in a variety of environments including:• Desktop, Web, and Mobile
