Feature layers provide a powerful and easily configurable way to serve features to a client. They are an easy way to build an application that accesses gigabytes of data and allow for rich interaction on the client while maintaining excellent performance.

Features to note:

• JS API Feature Layers
• Query hundreds of MBs of data, fetch results and display features in ~1s or less
• Custom scale dependencies for fine-grained control over which layer displays at a specific scale
• Interactive filtering via a slider
