Examples

Rooftop Solar Potential

This interactive application leverages the Tool API to enable users to draw custom geometries that retrieve filtered GeoJSON data from an ESRI FeatureService. The application creates a dynamically styled GeoJSON layer to visualize solar potential data, helping users identify optimal locations for solar installations. View the app and code here.

Sales Dashboard

Create powerful business intelligence tools by combining Felt's layer statistics with popular charting libraries. This example demonstrates how to build interactive visualizations that leverage layer filters. View the app and code here.

Custom legend with nested folders

Enhance map usability with a custom legend that extracts and uses FSL styling information to generate SVG icons. The code demonstrates how to build a nested folder structure with visibility toggles using layer filters, providing a pattern for organizing complex data layers. View the app and code here.

Inset maps

Build comprehensive multi-view dashboards by embedding multiple Felt maps on a single page. This example demonstrates how to create synchronized map views that communicate with each other, enabling users to simultaneously view different geographic contexts or zoom levels of the same data. View the app and code here.

Lens Map

Create engaging interactive experiences with customizable map lenses that reveal different data layers or styling as users explore. This technique allows for compelling before/after comparisons or the ability to highlight specific data attributes within a defined area. View the app and code here.

Isochrones

Provides a pattern for integrating third-party geospatial APIs with Felt maps. This example demonstrates how to make API requests based on element geometry and map interactions, process the returned data, and visualise isochrones as dynamic layers. View the app and code here.
