OpenLayers is a high-performance, feature-packed JavaScript library for creating interactive maps on the web. It can display map tiles, vector data, and markers from any source, supporting tiled layers, OGC services, and vector formats like GeoJSON, KML, and Mapbox vector tiles.
Use cases
- embed an interactive map in a web page
- display OpenStreetMap or Bing map tiles
- render GeoJSON or KML vector data on a map
- build a custom web GIS application
- show markers and vector overlays from any tile source
- create a slippy map with custom projections
- visualize Mapbox vector tiles in the browser
When to choose
- you need a full-featured, free, open-source mapping library for the web
- you must support many tile sources, OGC services, and vector formats
- you need fine-grained control over projections and map rendering
- you want a mobile-ready, high-performance map with Canvas/WebGL rendering
When to avoid
- you only need a simple embedded map with minimal code (Leaflet may suffice)
- you need native mobile or desktop mapping rather than web
- you want a hosted map service rather than a client-side library
