01The context
Stakeholders needed to see real estate transactions, valuations, and market trends on a map, both as interactive dashboards and as PDF reports they could share.
02The challenges
Maps inside reports
Telerik Reporting had no native support for interactive maps, and iframe-based maps could not be exported to PDF.
Large datasets
Reports needed to plot 10,000+ points without slowing down or crashing the browser.
PDF exports with maps
Exports had to include map snapshots with every marker and overlay rendered, generated on the server.
03What we did
01
Hybrid map-report viewer
Interactive mode uses Mapbox GL JS next to Telerik report panels; export mode uses the Mapbox Static Images API to embed high-resolution maps in PDFs.
02
Clustering and heatmaps
Point clustering and heatmap layers, backed by server-side aggregation by map tile, reduced client-side rendering load by around 90%.
03
Server-side snapshots
A custom pipeline renders GeoJSON overlays on static map images so PDF exports match exactly what users see on screen.
